Welcome to Vela’s Argus® family of professional MPEG-2 audio/video encoders. This manual is delivered to users of the Argus Spectrum, Argus 4:2:2, Argus 4:2:0, and Argus analog encoders (including Argus LC). Unless there is a note to the contrary, you should assume that the information and instructions in this document apply to all Argus encoding products. The generic name Argus is used throughout this manual to refer to all Argus encoding products. In the absence of a note to the contrary, you should assume that such “Argus” references apply universally to the Argus Spectrum, Argus 4:2:2, Argus 4:2:0, and Argus LC analog encoders. Individual product characteristics and/or operating functions that set one model apart from the others will be identified as necessary. Remember, too, that if you would like to have your own specialized user interface, Vela offers a Software Developer's Kit (SDK) that programmers can use to create customized applications. For more information about the Argus Encoder SDK, contact your Vela sales representative. Of course, if you have questions that this document doesn't answer, help is just a phone call away. Just dial or e-mail our customer support line at the number or address listed at the end of Chapter 1. Argus encoders share software among the various models. All use Vela's EDL (Encode Decision List) Editor to manage the encoding process. And the graphical user interface (GUI) allows for easy operation within a user-friendly Windows® environment. Note that there are some limitations to the feature sets provided with the various encoder models, as specified in the chart below:

Argus Spectrum Argus Spectrum, Vela’s flagship of the Argus fleet, reliably and efficiently transforms a wide variety of input signals into MPEG-2 digital streams that are unsurpassed in quality. At the same time that it's generating the high-bitrate, broadcast-quality MPEG-2 stream upon which Vela has built its reputation, Spectrum can produce up to three other low-bitrate digital streams, each in its own popular format. That's right, you can now generate high-bitrate and low- bitrate representations of the same source material simultaneously. We call this process multi-stream encoding. While the broadcast-quality stream will be in MPEG-2 format, the lower bitrate streams are available in Ligos® MPEG-1, Real® Media, and Microsoft® Windows® Media™ formats. Each of the formats is sold and licensed separately, allowing you to customize your encoder with one, two or all three low-bitrate encoding options. Argus Spectrum creates the primary digital stream at any of a number of video resolutions, including MPEG-2 D-1, MPEG-2 4:2:2 profile, MPEG-2 half-D1, and MPEG-1 SIF. When the primary stream is set up as a full-resolution MPEG-2 stream whose bit rate is greater than 6 Mbps, the Argus Spectrum also supports multi-stream encoding. The multi-stream encoding option allows you to create one to three secondary low-bitrate streams while you're encoding the primary MPEG-2 stream. The Spectrum encoder accepts composite video, as well as serial digital video (SMPTE 259M). It also supports up to four channels of analog or digital (AES/ EBU or S/PDIF) audio when the multi-stream encoding option is turned off.

Argus Spectrum Quick Start Guide 3

Furthermore, Spectrum supports closed captioning encoding for broadcast and cable applications. When it comes to archiving audio/video material, no other product fits the bill as well as Argus Spectrum. Because the low-bitrate streams are created in most popular formats, you can browse them readily on your personal computer with your favorite media viewer. And because the Spectrum is capable of generating them at very low bitrates, you can store them compactly on a disk drive. Mean- while, you can copy the high-bitrate MPEG-2 streams to a CD-ROM or to a remote server for later viewing or broadcasting. Best of all, the high- and low- bitrate streams are produced simultaneously in a one-pass encoding process! Of course, archiving is just one of the many ways that you can put the Argus Spectrum to use. Regardless of how you plan to use the Spectrum, Vela's user- friendly graphical user interface (GUI) makes it easy for you to configure the encoder to meet your own particular needs. And with the click of a button, you can reconfigure it quickly and easily as your needs change. Argus 4:2:2 Vela's Argus 4:2:2 encoder represents the latest in professional audio/video MPEG-2 digital encoding systems. The Argus 4:2:2 is designed to run smoothly under the Microsoft Windows 2000 and Windows NT™ operating systems, creating digital streams in a number of video resolutions, including MPEG-2 D-1, MPEG-2 (both 4:2:2 and 4:2:0 profiles) full-resolution, MPEG-2 half-resolution, and MPEG-1 SIF. For your convenience, the encoder accepts a wide variety of input signals. On the audio side, Argus 4:2:2 supports four channels of analog or digital (AES/EBU or S/PDIF) audio (see the Glossary in Appendix D for definitions of these terms), and supports closed captioning encoding for broadcast and cable applications. On the video side, it supports standard composite analog format, as well as serial digital interface (SDI) video. The encoder input accepts composite video, as well as component serial digital video (SMPTE 259M). Optional Argus Spectrum software is available that allows simultaneous real-time creation of Ligos MPEG-1, Real G2 and Windows Media-formatted streams. The Argus 4:2:2 uses the popular Vela CineView® Pro decoder for confidence monitoring and video clip playback. Argus 4:2:0 The analog only Argus 4:2:0 encoder supports creation of MPEG-1 SIF and MPEG-2 half- and full-resolution streams. Argus 4:2:0 accepts composite and

Argus 4:2:2 4 Argus Encoder Family Version 2.6 Installation and User Manual component serial digital (SMPTE 259M) video inputs, and supports four channels of analog or digital (AES/EBU) audio. The Argus 4:2:0 encoder supports closed caption encoding for broadcast and cable applications. Optional Argus Spectrum software is available that allows simultaneous real-time creation of Ligos MPEG-1, Real G2 and Windows Media-formatted streams. The Argus 4:2:0 uses a Vela CineView Pro LE decoder for confidence monitoring and video playback. Argus LC Vela’s Argus LC low-cost encoder board is designed for the professional creation of MPEG-1 and MPEG-2 audio and video streams in a cost-effective, economical manner. The LC encoder is derived from the Argus 4:2:0 Windows-based encoding system. Argus LC accepts composite video inputs and supports two channels of analog audio. The LC encodes in MPEG-1 SIF, MPEG-2 half-resolution and MPEG-2 full-resolution formats at MPEG-2 bit rates up to 15Mbps. It accepts composite video inputs and supports two channels of analog audio. The Argus LC encoder supports closed caption encoding for broadcast and cable applications. Argus LC ships as a board-level product, (standard length PCI form factor) allowing for full custom installation and configuration. The Argus LC board is upgradeable to Argus Spectrum multi-stream software, allowing the creation of MPEG-1, Real G2, and Windows Media-formatted streams. The Argus LC is designed for use with the Vela CineView Pro LE decoder (sold separately) for confidence monitoring and video playback. Argus Encoder Family Features

Common Features Features common to the entire Argus encoder family are described below. Model-specific features are listed in the respective sections to follow. • VBR Encoding: (Standard on Spectrum and Argus 4:2:2; optional on Argus 4:2:0 and Argus LC) To optimize the video quality at lower bit rates, use the RegCtrlPnl application to turn on VBR (variable bit rate) encoding and to set the average bit rate. During the course of the encoding process, Argus will adjust the video bit rate based on the difficulty of the scene that it is encoding. The maximum bit rate that it will use is the video bit rate (or mux rate) that you specify on the EDL Editor property page for each clip. Note that VBR encoding is not available with the three-chip (ME31) Argus encoder board.

Argus LC Quick Start Guide 5

• Multi-stream Encoding: Argus Spectrum software allows you to produce up to four encoded streams simultaneously: one high-bitrate MPEG-2 stream, combined with one or more low-bitrate Ligos, Real Media, or Windows Media-formatted streams.

Argus Encoder Family Features 8 Argus Encoder Family Version 2.6 Installation and User Manual

• Two-channel analog audio. • Uses available Argus cables, SDK, etc. Order separately. • Most inexpensive way to get started in MPEG-2 hardware encoding. • Great for systems integrators looking for economy systems. Installation For detailed instructions on installing or upgrading your Argus encoder hardware and/or software, please refer to Chapter 1. If you purchased the Spectrum multi-stream encoder, remember that, if you plan to use one of the multi-stream encode options, you must connect the programmed Aladdin HASP® software protection key (sometimes know as a “dongle”) to the parallel printer port of your encoder before starting the EDL Editor application. Once your Argus hardware and software are properly installed, follow the instructions in the next section to connect to the audio/video source and to a monitor. Connecting to the Outside World To use Argus MPEG-2 encoders, you will need a video source. Although the Argus accepts a wide variety of video and audio inputs, both analog and digital, it does require that the video source be of professional quality or better.Because of time-base errors that are found in the video, a consumer-grade VTR will not work satisfactorily. For this example, let's assume that you have access to a professional-quality VTR like the Sony® Betacam® SP™ deck. • Connect the video using a 75-ohm BNC-to-BNC cable from the VTR output to the encoder's video input. • Audio requires two to four XLR cables, one each for the left and right audio output channels from the deck, or one for each of four channels, should the source deck support multiple channels. Use the XLR connectors found on the supplied six-connector audio input cable for this purpose. This cable is not supplied with the Argus LC and can be ordered separately. • If you'd like, you can connect a serial cable from the remote control connection on the source VTR to the RS-232/RS-422 protocol (level) converter supplied with your encoder. Then connect the level converter output to the encoder communications port (COM1 or COM2). This allows the Argus to pre-roll the tape, to start the encode precisely on the requested mark-in, and to stop the tape deck when the encode is finished.

Installation Quick Start Guide 9

After connecting your Argus to an audio/video source, you'll probably want to connect it to a video monitor, which you'll use as a confidence monitor during the encoding process. Just use a BNC-to-BNC cable to connect the video output of the CineView Pro family decoder to the video input connection of the monitor. You'll also need cabling to connect the audio output of the CineView Pro decoder to the audio inputs of the monitor or other audio system. The decoder requires a 15-pin high-density D-sub male connector attached to two audio cables (left and right), each of which, in turn, connects to the monitor. Refer to the end of Chapter 1 for pin-out drawings and other cabling information. These audio cables can be ordered from Vela if desired. Using the Argus Encoder Now for a quick introduction to encoding and playback of the MPEG streams that Argus encoders generate. For more detailed information on the encoding process, please refer to Chapter 2, “Using the Argus Encoder.” Boot the Encoder The first step is to start the computer that plays host to the encoding system. Argus software is normally configured with two user names: ADMINISTRATOR and ARGUS. ADMINISTRATOR can perform some functions that are not available to the ARGUS user. As delivered, the password for both user names is “mpeg-2” (lower case, no quotes). You can change these as you like, but don't forget them! NOTE: It is important not to use a screen saver. If a screen saver should activate during an encode, it is likely that the encode process will halt and fail. Start the RegCtrlPnl Program Let's start by opening the Vela Registry Control Panel application (RegCtrlPnl), which allows us to set a few advanced settings for the encoder as well as to set up parameters for a multi-stream encode. There should be a RegCtrlPnl icon on your desktop. If so, double-click it to activate the application. If not, click the Start menu, then Programs, then Vela Research, then RegCtrlPnl. In either case, you'll see the Registry Control Panel screen pop up, with the tab (or property sheet) labeled “Argus” in full view. If for some reason the “Argus” tab does not appear on your Registry Control Panel screen, just right-click on the toolbar at the top of the screen, then make certain that the “EDL Mode” selection on the bottom of the menu is checked. If not, check it now. On the Argus property sheet, just accept the default settings. These are advanced encoder settings that apply to the MPEG-2 stream (or “primary” stream in the

Using the Argus Encoder 10 Argus Encoder Family Version 2.6 Installation and User Manual case of Spectrum). For a full explanation of each setting, see Chapter 2. Note that clicking Apply causes RegCtrlPnl to save your property settings to the Windows Registry. When EDL Editor begins to encode a clip, it uses whatever multi-streaming parameters are currently saved in the Registry. It re-reads these properties before starting each encode. On Spectrum models, behind the “Argus” tab, you'll see at other tabs on the Registry Control Panel screen. The properties on each of these remaining tabs (or property sheets) apply to the secondary low-bitrate streams. Specifically, there will be a Multi-Encode tab plus one tab corresponding to each of the multi-stream low-bitrate format packages installed on your Argus Spectrum. Since the three different formats (Ligos MPEG-1, Real Media, and Windows Media) are sold separately, your installed version of Registry Control Panel may show only one or two of these format-specific tabs. Each of the three multi-streaming property sheets has a checkbox at the top, allowing you to turn on or off the multi-streaming option for that particular format. When you run an encoding session, the Argus Spectrum will create (by default) an MPEG-2 primary stream; additionally, it will create a “secondary” low-bitrate stream corresponding to each of the property sheets for which the “enabled” checkbox is checked. For this first encode, check one of the checkboxes (either the one on the Ligos tab, the one on the Real tab, or the one or the Windows Media Video tab). On the Multi-Encode property sheet, select either SIF or QSIF resolutions. Then click Apply to accept the remaining default parameters for the multi-stream encode. Don't enter a file name on the Ligos, Real, or Windows Media property sheet, since EDL Editor will supply a file name for you, based on the full path name of the MPEG-2 file that you're encoding. Start the EDL Editor Now let's open the EDL (Encode Decision List) Editor. If there is not already an EDL Editor icon on your desktop, you will find the application by clicking the Start menu, then Programs, then Vela Research, then EDL Editor. Otherwise, just select the EDL Editor icon and watch the welcome screen pop up. After waiting a few seconds as the software initializes, you'll see the EDL window with an empty list. Create a new encode list by clicking on File menu > New. Name the list you will build by selecting the File menu > Save As option. When prompted, enter the name you would like to use for the list of encode settings. For example, you may group various sports clips together into a list called “Sports.”

Using the Argus Encoder Quick Start Guide 11

Create a Template EDL Editor sets the properties for the MPEG-2 (or Spectrum “primary”) stream by using a template. So, before you create a clip to encode, there must be at least one template in your template list. Note that if you allow the software installation application to create a new database for you, that database will already have two default templates, one named “NTSC,” and the other named “PAL.” In selecting a template for your first encode, you may choose to do any one of the following: • Select an existing template, unmodified (either “NTSC” or “PAL,” depending on the video standard that you'll be using). • Create and add a totally new template to the template list. • Modify and save an existing template. Let's assume that you've decided to create a new template. Just follow these steps: 1. Click on the Clip Template button on the toolbar to activate the Template Management window. 2. Click on the Add Template button of the Template Management window. You'll see a screen asking for Name and Description. Fill in these fields and press OK. The MPEG Settings screen will pop up. 3. On the MPEG Settings screen, enter the encode property settings for the template. If, for example, you plan to encode a list of basketball games, you might name the template “Basketball” and set the template to an average MPEG-2 bitrate, for example 10 Mbps. Set the file storage type to Mux Only. 4. Then set up the remaining properties according to the following table:

Property Setting

Video Input Composite (assuming an analog composite source is connected). Video Format Select 4:2:2 if that option is available on your encoder model. Horizontal Res 720 Bit Rate 10.00 Audio Input Analog Audio Mode Stereo Audio Bit Rate 192000

Using the Argus Encoder 12 Argus Encoder Family Version 2.6 Installation and User Manual

Property Setting

Multiplex Format Transport Stream Mux File D:\mpegfiles\test.mpg (Check the box.) Audio Elementary Leave unchecked. Video Elementary Leave unchecked. Clip Name Test Clip Desc Test clip

Clicking OK will save the template settings in the database. Once you've saved the template, you can use it to create clips. Note, though, that the template settings apply only to newly created clips for which that template is selected. There is no way retroactively to apply template settings to an already-created clip. (Of course, you can always edit the property sheet for the already-created clip. The “Modify a Clip” section, below, tells you how). Create a List of Clips Now you are ready to create a list of clips. Click on the New Clip button. This brings up the Clip Settings window, which allows you to select a template and enter some specific parameters for the clip (particularly for the Spectrum MPEG-2 primary stream). Select the template that you just created. Give the clip a name. Notice that the editor assigns a default file name based on the clip name and the list name. Change the file name, if you wish. Spectrum users should note that the path and file name that you assign to the primary stream will also be used for each of the secondary streams that you generate simultaneously; just the file extension will be changed. Now click on the VTR Control button to access the VTR Control window. On this window, you may set a mark-in as well as a mark-out or a duration for the clip, based on the time-code settings of the tape that you're encoding. (If you are using a “live feed,” make sure that the Enable VTR button is not selected, entering just the duration or length of the clip that you'll be encoding). If you are encoding from a tape, you can control the deck with the buttons shown in the windows. First, make sure Enable VTR is selected. Mark-in and mark-out points can then be set from the VTR Control window. Be sure to assign a positive, non-zero pre-roll value (2 is good). Click Finish to return to the Clip Settings window.

Using the Argus Encoder Quick Start Guide 13

Now that you have created a clip, click OK. The clip should appear in the Encoder Decision List on the main screen. Check the settings of the clip as they are displayed on the list. They should match the parameters that you've saved. Create several more clips, just as you did the first, adding each to the list. Be sure to give each a different clip name and file name. When you're finished, save the list by clicking Save on the File menu or by clicking the Save button on the toolbar. On the Save dialog box, name the list (if you haven't already done so). Finally, click OK to store the clip parameters in the database. Modify a Clip Now you have both a clip list stored in the database and a group of Windows Registry settings identifying the parameters for encoding your secondary streams. Note that EDL Editor gives you the tools to modify any of these settings at any time prior to starting an encode. To modify the MPEG-2 stream (or Spectrum “primary” stream) settings of a specific clip, just open the clip list so that it is displayed on the main EDL Editor screen. Next, double-click on the entry in the EDL that represents that clip that you'd like to modify. The Clip Settings dialog will pop up. You'll recognize it as the same dialog that you visited when creating the clip template. Now change any of the properties on the screen (or on the VTR window) that you'd like to modify. Remember that these changes apply only to the specific clip that you have selected, not to any other clips or templates in the database. When you're finished, click OK. Encode a Clip Now it is time to encode a clip. Select one of the clips in the list and click on the Encode Selected icon on the toolbar. If you entered mark-in and mark-out time codes on the VTR Control window, the tape deck should now begin to pre-roll. Shortly the deck will begin to play, and the encoding session will begin. After a short delay, you'll see the MPEG-2 stream playing back on the monitor that you connected to the CineView Pro decoder board. Below the EDL, you will see a progress bar filling left-to-right, indicating the percentage of the encode that has been completed so far. Once the encode is finished, the deck will stop and a progress bar will appear at the bottom of the EDL window indicating the progress of the indexing task. Next, all of the icons will return to their normal state and a message will appear at the bottom of the EDL indicating that the encode is finished. If a problem occurred

Using the Argus Encoder 14 Argus Encoder Family Version 2.6 Installation and User Manual during the encode, a message box will pop up listing a specific error code. In most cases, you'll be able to identify the encoding error by looking up the error code in the table in Appendix B. Play Back a Clip Now let's play back the files that we just created. Select the View menu from the EDL menu bar and click on Playback Mode (or click the Vela sails playback icon on the toolbar). The CineView Pro application will pop up. Now click on the Play icon of the pop-up window and watch the encoded clip play back. For detailed instructions using the CineView Pro playback application, please refer to the CineView Pro Decoder Family User Manual and API Guide. For Spectrum users: To play back the primary MPEG-2 stream, click on the Vela sails playback icon on the toolbar. The CineView Pro application will pop up. Assuming that the clip that you just encoded is still highlighted on the EDL, all that you need do is click the Play icon on the pop-up window, then watch the encoded MPEG-2 stream play back. To play back an Argus Spectrum secondary stream, use Windows Explorer to navigate to the folder where the clip is stored. Note that the secondary stream will have the same base name as the MPEG-2 clip, but its file extension will be different. The extensions that apply to the secondary stream are: *.mpe Ligos MPEG-1 *.rm Real Media (G-2) *.wmv Windows Media Video Once you've located the stream that you'd like to play back, just double-click on it to activate the Windows Media Player or the Real Player application. (You may need to install these applications if they are not already installed on your system.) Note that you may view the Ligos MPEG-1 secondary stream by using either the Windows Media Player or the CineView Pro playback application. If you use the CineView Pro application to play back the stream, just enter *.mpe in the file name field to see your clip in the files list. That’s all there is to it. You’ve just joined the growing ranks of Argus users!

Using the Argus Encoder

Chapter 1 Getting Started Overview The Vela Argus family of MPEG-2 encoders consist of high-quality audio/ video encoding systems or boards hosted on a Microsoft Windows 2000 or Windows NT PC operating system. Argus encoders use hardware and software developed by Vela to convert traditional audio and video signals into studio- quality MPEG-2 digital and/or analog streams. The resulting MPEG-2 compressed video can then be stored on a hard drive and/or transferred via a network, ultimately to be decoded with an MPEG-2 compliant decoder for broadcast or personal viewing. An easy-to-use graphical user interface (GUI) offers a wide range of encoding options and allows for fast, efficient operation within a user-friendly Windows environment. Vela manufactures the single-board PCI encoder used in the Argus. The board features an IBM® MPEG-2 encoder chipset to compress and encode video data received from composite or digital sources. In addition, two digital signal processors compress and encode up to four channels of digital or analog audio. The encoder includes two high-performance Intel® Pentium® III processors. Argus Spectrum, 4:2:2 and 4:2:0 encoding systems are packaged in rack-mountable enclosures, four rack units in height. The Argus LC comes as a board-only product. Other Argus systems can be ordered in board-only configurations or as encoder/decoder board sets. Ask your Vela representative for details. System Requirements

Power and Environmental Requirements • Commercial 115/230 VAC 50/60 Hz. We recommend the use of an uninter- ruptible power supply (UPS) with a minimum capacity of 175 watts. • Operating temperature not to exceed 95° F (35° C). • Relative humidity between 20% and 80%. Please refer to Appendix A for complete specifications. Other Requirements • Program Source: The input video source must provide a stable video signal. Suitable sources include professional video tape recorders (VTRs), laser disc players, and tuners receiving off-air or satellite broadcast signals.

Overview 18 Argus Encoder Family Version 2.6 Installation and User Manual

Consumer-grade VCRs do not, in general, provide a suitable source unless a time base corrector is used. A poor input video source will be reflected in the resulting output video stream(s). • Video Output: Argus encoders encode and output video in either PAL or NTSC format, as desired. The output of the encoder, through a Vela CineView Pro decoder board, may be fed to standard video devices, such as distribution amps, routers, switchers, and VTRs that accept composite or SMPTE 259M video in the desired format(s). BNC connectors are used on the decoder board for video handling purposes. For monitoring the output of the encoder, there are many suitable video display devices. The display must accept either composite baseband video or serial digital (SMPTE 259M) video. Although a television receiver with a video input is acceptable, for many applications you may prefer a professional video monitor. • Audio Output: The CineView Pro family decoders, supplied with all Argus models except for the LC, supplies a “line-level” (+4 dBm) audio output signal, which works directly with professional broadcast audio equipment. Argus encoders are supplied with audio output cables specific to the model ordered. All are populated with professional or broadcast-grade signals in analog and/or digital formats, with which professional audio equipment may be connected. Argus Encoder Installation Your Vela Argus encoder model, except for board and board set versions, arrives in two shipping boxes. Box one contains a 17-inch color monitor with related hardware and installation instructions. The second box contains the Argus encoding unit, an AC power cord, a 9-pin RS- 232/RS-422 protocol (level) converter, audio cables, a keyboard, and a mouse. Box two also contains a Microsoft Windows operating system CD-ROM, a Vela system software CD-ROM, and a CD containing sample MPEG files. Spectrum users are furnished a pre-programmed Aladdin HASP® software protection key (sometimes know as a “dongle”), that grants or denies permission to use each of the multi-stream encoding components.

Unpacking, Mounting, and Connecting the Argus Encoder Follow these steps to install your rack-mount Argus encoding system. 1. Carefully unpack the encoder from its shipping container, checking for damage to the container or its contents. 2. Attach the supplied rack ears to the encoder and install the encoder into the desired equipment rack. NOTE: If rack slides are not used to support the encoder, attach a suitable rear support (e.g., a blank panel) to the rear of the rack to relieve pressure on the rack mounting ears. 3. (Figure 1-20) Attach the power cable from an approved AC power source to the AC power connector on the rear panel of the Argus. 4. If the power supply on your Argus encoder has a voltage selector switch posi- tioned next to the AC power connector, set the proper voltage for your country. If there is no such selector switch, the power supply is an auto-sensing model and will automatically select the proper voltage.

Argus Encoder Installation Chapter 1 — Getting Started 21

5. (Spectrum users only) Plug the supplied, pre-programmed Aladdin HASP® software protection key (“dongle”) into the parallel (printer) port of your Argus encoder. If a printer is to be used, plug its cable into the back of the HASP device, so that the HASP device is between the parallel port and the printer cable. Soft- ware for the device will be automatically installed during software installation. 6. Connect the audio input and output cables to the respective encoder and decoder connectors. The encoder input cable has a male 26-pin D-Sub connector at one end and six female XLR connectors at the other. The decoder board output cable has a 15-pin D-Sub connector and three male XLR connectors. Both cables are labeled for ease of connection. 7. Connect the audio source to the encoder input cable and the video source to the appropriate BNC connector found on the Argus single-slot encoder board (Figure 1-20). 8. Go to “Hardware Installation Completion,” page 22, for final instructions. Rear Panel Connections (Figure 1-20) Your Argus rack-mount encoder comes complete with rear-panel connectors and audio umbilical cables through which input and outputs are routed. The following connectors are available on the rear panel: SDI (Serial Digital Interface) — This input, found on the encoder board, refers to the SMPTE 259M component serial digital video format, an interface standard for high-end component digital video systems used in broadcast and production environments. (Spectrum and 4:2:2 models only.) COMPOSITE VIDEO IN — This input is for standard NTSC or PAL analog composite video. It is found on the encoder board. DIGITAL VIDEO OUT — Provides digital video output in 4:2:2 serial format (SMPTE 259M). Located on the CineView Pro decoder board. The CineView Pro LE decoder supplied with the Argus 4:2:0 does not have this connector. COMPOSITE VIDEO OUT — Provides analog video output. Located on the CineView Pro/Pro LE decoder boards. GENLOCK — Input port for connecting an external video source with which to lock the output video. Located on the decoder board. AUDIO INPUT — The following connections are found on the audio input cable supplied with the Argus. The cable plugs into the 26-pin D-Sub connector located on the encoder board. See Figure 1-21. • Analog Audio: Female XLR connectors are provided for four channels of

CineViewPro Sub-Folder Contains within it a folder titled “Windows 2000,” which contains Saa7146.inf and Saa7146WDM.sys. Optional SDK Vela offers a Software Developer's Kit (SDK) for the Argus encoder family. You'll sometimes hear this kit referred to as the Argus API (Application Programming Interface). The API is an important component of the SDK. The SDK is a tool kit that allows computer programmers to design and implement specialized functionality for the encoder. For example, if your operation requires a customized user-interface with a different look and feel than that of the EDL Editor, a computer programmer could create such an interface using the SDK. You've probably noticed that one of the selections on the Argus CD-ROM Autorun interface is Install SDK. Available only to customers who purchased the Argus SDK, this installation option is password-protected. See page 39 for installation information. Contact Vela directly or call your area sales representative for pricing and availabil- ity of the Argus SDK. If you have already purchased the SDK, refer to the Argus API Developer's Guide for complete instructions on using the kit. Uninstalling Argus Software If you must uninstall Argus encoder software, always use the Windows Control Panel > Add/Remove Programs application. Never manually remove any files installed by the Argus installation process, as doing so may prevent proper removal of some or all of the files installed. Note that complete removal of the product with Add/Remove Programs is possible only if the product was originally installed in the default target folder created by the installation process. In most cases, when you upgrade to version 2.6, you'll be removing a previous version of Argus software from the encoder. To uninstall that previous version of software, consult the user's manual that you received when you installed it.

Uninstalling Argus Software Chapter 1 — Getting Started 29

Uninstalling Software Version 2.6 At some point, you may need to uninstall Argus version 2.6 from your system. To do so, just follow the steps below. 1. On the software list that is displayed when you select “Add/Remove Programs” from the Control Panel, click on the entry that begins with the phrase “Vela Research, Software Version ….” Then click the “Change/Remove” button. 2. In some cases you may see a message similar to: “The system indicates that the following shared file is no longer used by any program and may be deleted….” If you see this message, click on “Yes to All.” 3. After uninstalling and removing the software, the system will reboot automatically. 4. When the machine has finished rebooting, there should be no file entries in the C:\Program Files\Vela Research folder. If you find files or folders remaining in the C:\Program Files\Vela Research folder, delete them manually. Uninstalling Hardware Drivers The procedure for uninstalling hardware drivers in preparation for removing the Argus encoder board from the system is outlined below. 1.

If it is important to you to keep your existing database (clip lists) after you upgrade to Release 2.6.5, be sure to save the file C:\vela_db\BArgus.mdb on a floppy disk or in a folder other than C:\vela_db. When you have finished installing the new Argus software, you can copy your saved version of BArgus.mdb back into the C:\vela_db folder. Argus 2.6 Installation Scenarios

Be sure to review the “readme” files on the system software CD-ROM for the very latest information on installation and performance issues. If you purchased a new Argus encoder, it is likely that all of the software that you need to run the system is already installed and “burned in.” On the other hand, if you are upgrading an existing system to version 2.6 or to run on Windows 2000, you'll need to install the software using the CD-ROM disc that is supplied with the Release 2.6.5 upgrade. All of the software that you need to install Argus system software, Release 2.6.5, along with the latest versions of CineView Pro and CineCast, is located on the CD. Just follow the instructions to install Release 2.6.5, noting that a number of system reboots may be required during the installation process. Be sure to leave the CD- ROM disc in the drive until the entire installation procedure is complete. See the following situations below for your particular Argus encoder installation. Case 1 — New Argus Encoder with Pre-installed Windows 2000 and Version 2.6 Go to “Logging On and Starting Up,” page 46, for startup instructions.

Logging On and Starting Up

The following steps will power up the Argus encoder and prepare it for operation. NOTE: Screen savers should be deactivated. If a screen saver should activate during an encode, it is likely that the encode process will halt and ultimately fail. 1. Apply power to the Argus encoder by depressing the power switch on the front panel. As the encoder is booting, various data appear on the screen. Soon, the Windows splash screen followed by the Begin Logon window will appear. 2. To log in, press the Control, Alternate, and Delete keys together (Ctrl/Alt/Del) in the typical “warm boot” sequence. When the Argus “Logon Information” dialog box appears, type as shown: Username: ADMINISTRATOR Password: mpeg-2 NOTE: Letters in the Username are not case sensitive; however, letters in the Password must be typed in lower case. 3. Click the OK button in the Logon dialog box, or press Enter. 4. The “Welcome to Windows 2000” (or “Welcome to Windows NT”) message will appear. There are four selections in the window: What’s New, Help Contents, Next Tip, and Close. When finished using the features of this window, click the Close button. 5. Be sure to set the correct date and time for your location. This makes overall operation more efficient and will allow the operating system to stay in sync with any networks that be may be connected to the Argus. Set the date and time through the Control Panel or double-click the clock icon on the Task Bar. For more information, consult your operating system manual or click Start > Help. 6. To open the EDL Editor, click Start > Programs >Vela Research > EDL Editor. You may want to create a desktop shortcut to it. Details on Startup folder shortcuts are contained in the following section. Changing the Startup Menu Placing shortcuts in a special Windows Taskbar folder called “Startup” causes any applications or shortcuts that reside in that folder to be launched when the user logs on. Two such folders exist. One is owned and maintained by Adminis- trative users. The other is user-specific and may be maintained at the user level by the current user.

Logging On and Starting Up Chapter 1 — Getting Started 47

A shortcut to the Argus EDL Editor is installed in the Startup folder for user “ARGUS” when the software is installed at Vela. Thus, when user ARGUS logs on to the system, the EDL Editor application will launch automatically. System Configuration Settings There are two special Windows Registry settings that inform Argus applications that the encoder is configured in a unique way: without the decoder board installed or without a VTR installed. If Spectrum software is installed on your system, you will NOT be able to use the encoder without a CineViewPro decoder board. How- ever, you may elect to turn off the VTR-installed option if you will not be using a VTR as a source. Just follow these steps: 1. From the Windows start-up menu, select the “Run” option. 2. In the “Open” edit box of the “Run” window, type regedit, then click OK. 3. On the “Registry Editor” window, click the “+” symbol next to the HKEY_CURRENT_USER option. The list of settings for HKEY_CURRENT_USER will drop down. 4. Click on the “+” symbol to the left of the “Software” list entry 5. Click on the “+” symbol to the left of the “Vela Research” list entry. 6. Click on the “+” symbol to the left of the “Broadcast Argus” list entry. 7. Click on the “EncoderConfig” entry. In the list to the right of the window, you'll see “DecoderInstalled.” 8. Double-click on the “VtrInstalled” entry. The “Value” window will pop up. 9. Change the value in the pop-up window from a “1” to a “0.” Then click OK. NOTE: While exploring the EncoderConfig table, it would be wise to make certain that the “DecoderInstalled” option is set to “1,” not to “0.” Customer Support In the event of problems with your Argus encoder, refer to Appendix B for a listing of troubleshooting procedures and error codes for commonly encountered user problems. If the problem cannot be resolved through the troubleshooting guide, please contact Vela Customer Support as follows: • Phone: (727) 507-5301 • E-mail: [email protected] • World Wide Web — http://www.vela.com

Warranty Notice Before attempting to add any hardware or software to your encoder (extra hard drives, desktop utilities, etc.), please contact Vela Training and Support. Some devices and applications are not compatible with Argus encoders and their use could cause equipment damage. In such cases, the warranty could be invalidated. Returning Items to Vela In the event you need to return all or part of your Argus encoding system to Vela for repair or replacement, please try to use the original packing boxes and material. Secure all loose circuit boards, drives, and anything else that could become loose during shipment. Be especially careful to tie-wrap the extender handle of the encoder board to its nylon guide bracket, if not already done so, as shown in Figure 1-19, to prevent the board from dislodging and becoming damaged. This is important even though both the front and back ends of the encoder board are secured to the chassis with a bracket and screw. If you wish, you may remove the encoder board from the chassis and return it to Vela in an anti-static bag within a separate shipping container, well-protected from physical shock. Contact Vela Training and Support for more information and to obtain a Return Merchandise Authorization (RMA) number. An RMA is necessary before Vela can accept any returned goods.

MPEG Overview

The Moving Pictures Expert Group (MPEG) sets MPEG compression standards of the International Standards Organization and the International Telecommuni- cations Union/CCITT. Virtually all developers and manufacturers of video encoder/decoder equipment and software, including Vela, follow these standards. The MPEG-1 format is generally used for such non-broadcast applications as video delivery on a CD-ROM. MPEG-1 features a low bit rate of 1.15 to 3.0 Mbps, SIF resolution (352x240 pixels NTSC, 352x288 pixels PAL), a 4:2:0 profile, and frame-oriented syntax. MPEG-2 Main Profile is designed for use with high-performance broadcast and telecommunications applications. MPEG-2 features CCIR-601 (ITU-R-601) resolution (704x480 or 720x480 pixels NTSC, 704x576 or 720x576 pixels PAL), a bit rate of 3–15 Mbps and the concept of scalability. It also provides support for the interlaced format, a 16:9 video aspect ratio, and multiple video and audio channels within the same stream. MPEG-2 is backward compatible with MPEG-1. The MPEG committee also defined a high-end format specifically for handling studio quality video. This is the 4:2:2 profile of MPEG-2. While the MPEG-2 main profile subsamples the color space to 4:2:0 format prior to encoding, the 4:2:2 profile maintains the full color resolution carried in the CCIR-601 video. This makes the 4:2:2 profile more applicable for studio use in which a picture may be encoded and decoded several times before it is finally transmitted to the home. 4:2:2 profile includes the vertical blanking interval in the encoded stream as well, carrying closed captioning, teletext, and other data services transparently through the encoding/decoding process. The MPEG-1 System stream consists of variable length audio/video packets, known as Elementary stream (ES) packets, multiplexed together. Each ES packet has a header and a payload. The payload contains contiguous bytes of Access Units (AUs), coded representations of audio/video frames. ES packets are arranged as packs, with pack headers and occasional system headers. The principal function of decoders is to decode AUs from bitstreams. The semantics of the MPEG stream and constraints on those semantics require the exact definition of decoding events and their times. To help synchronize the decoding process, time stamps propagate with the coded data. This information is used to calculate exactly the time a particular byte enters the decoder, is buffered and is presented.

MPEG Overview 56 Argus Encoder Family Version 2.6 Installation and User Manual

The compressed data consists of video or audio sequences. Each video sequence, in turn, comprises one or more Group of Pictures (GOP) units. Each GOP is made up of pictures, which is the AU for video. As is generally true in the world of digital encoding, there is a trade-off between random accessibility and compression. MPEG algorithms exploit spatial and temporal redundancies in the data and capitalize on the natural non-linearity of human vision. The MPEG-2 Program stream is analogous to the MPEG-1 System stream with certain differences. Program streams contain Packetized Elementary Stream (PES) packets, as opposed to MPEG-1 packets. Program streams are meant primarily for error-free environments such as multimedia applications. PES packets can be any length, and program definitions are encoded with this stream. The MPEG-2 Transport stream is a combination of one or more programs, with the packet size fixed at 188 bytes. Transport streams are meant primarily for broadcast applications and error-prone environments. Transport stream packets feature a header and payload. The header has a unique ID and can identify the contents. Transport stream packets can contain ES or Program Specific Infor- mation (PSI) tables that contain demultiplexing information. MPEG-1 and MPEG-2 audio bitstreams have three layers, with layer two commonly used. MPEG-2 provides three additional audio sampling frequencies and features multichannel, multilingual capability. Uses for MPEG-2 compression technology include CD-ROM, CD authoring systems, CD karaoke systems, Digital Video Disk (DVD) applications, and video telecommunications. Broadcast applications include video-on-demand (VOD), near-video-on-demand (NVOD), video archiving, ad insertion, Direct Broadcast Satellite (DBS), and Video on ATM (Asynchronous Transfer Mode).

MPEG Overview Chapter 2 Using the Argus Encoder

Introduction This chapter provides screen-by-screen descriptions of the steps involved in encoding, saving, and playing back video clips on your Argus encoder. If you want a faster overview of the process, refer to the Quick Start Guide located at the front of this manual. Starting Up Start the computer that plays host to the encoding system. Argus software is normally configured with two user names: ADMINISTRATOR and ARGUS. ADMINISTRATOR can perform some functions that are not available to the ARGUS user. As delivered, the password for both user names is “mpeg-2” (lower-case, without the quotes). You can change them, but don’t forget them! NOTE: Any screen saver currently in use should be deactivated. If a screen saver should activate during an encode, it is likely that the encode process will halt and ultimately fail. RegCtrlPnl One of the icons that will appear on your desktop when you've finished installing version 2.6 of the software is RegCtrlPnl, a tool that can be used to save encoding parameters in the Windows Registry. Before each encode, the EDL Editor reconfigures its encoding environment by rereading all Argus-related Windows Registry settings. Before starting the EDL Editor application, it's a good idea to visit and save all of the RegCtrlPnl property sheets. There are two general types of encoding parameters that are exposed through the RegCtrlPnl application: • There is one property page (labeled “Argus”) of advanced encoding parameters that apply to the primary MPEG-2 high-bitrate stream • For the Argus Spectrum, there are two to four additional property pages that allow you to configure the encoder for multi-stream encoding. For a detailed description of all of the settings exposed through RegCtrlPnl, please see Chapter 3.

Introduction 58 Argus Encoder Family Version 2.6 Installation and User Manual

The EDL Editor (Figure 2-1) The EDL (Encode Decision List) Editor screen is the main Graphical User Interface (GUI) window of the Argus encoder. The window contains a title bar, a menu bar, a toolbar, the encode list, and status displays. The name of the active EDL appears in the EDL List Editor title bar. The list displays some of the more important characteristics of the clips that appear in the currently opened encode list. The fields can be expanded or shrunk by clicking on the right-hand edge of the field name, holding down the left mouse button, and dragging the edge. The EDL Editor is opened by clicking the Windows Start menu, then Programs, then Vela Research, then EDLEditor. (You might want to create on your desktop a shortcut to the application.)

Template List – A list of available templates is displayed. Highlight the one to be used to form the new clip. Clip Title – Click and enter the title to be used for this clip. The title will be used to form a unique file name for the compressed video file. Clip Desc – Click here and type in a description of the clip. This is not used by the software system, but rather allows a description that may be useful to operating personnel working with the clip. Template Desc – Description of the template that will be used to create this clip (the template highlighted in the template list). Multiplexed File – This is the file name that will be used to store the compressed video file associated with this clip. A unique file name is automatically generated

Clip Management Chapter 2 — Using the Argus Encoder 67

when the clip title is filled in. This file name uses the file path that was provided by the template. The file name itself is the list name and the clip title placed together. The file extension is always .mpg. The file name and path can be changed at any time after the clip title is first filled in. VTR Control – Click here to bring up the VTR Control window (described below and shown in Figure 2-7). Finish – Click to complete the clip creation process. Cancel – Click to cancel the operation. No new clip will be created. Help – Online help is currently under development. Click on the Help > About drop down menu to reveal the current software version. VTR Control (Figure 2-7) The VTR Control window provides full control of a professional VTR. The VTR can be connected directly to the Argus using an RS-422 serial interface. VTR – This specifies the type of connection that is to be used for the VTR deck. Currently, the only supported selection is for Sony 9-pin. COM Port – Select the COM1 or COM2 port for device control. Note that if you change COM ports, you may need to exit, then re-enter this window. Preroll Seconds – Specifies the amount of time (in seconds) the VTR should play out prior to the desired frame. This gives the VTR time to come up to proper operating speed. For most VTRs, a value of two to five seconds is adequate. When “Enable VTR Control” is selected, the Preroll Seconds value should never be less than 1. Adjustment Frames – Since not all VTRs behave the same, it may be necessary to use an offset to achieve inpoint frame accurate operation of the VTR. Entering a number will cause the actual encode to be delayed by that number of frames. A negative number will cause the encode to start earlier. This will not affect the number of frames that are actually encoded. It only affects the starting point for the encoding process. NOTE: If inpoint frame accuracy is not properly set, the first encoded frame will not be correct. In addition, if inpoint frame accuracy is not properly set and the GOP time code adjustment box is selected (checked) in the Registry Control Panel (Chapter 3, Figure 3-2), time code insertion will not match the VTR source. Enable VTR Control – Check this box to allow the EDL Editor application to control (start and stop) the tape deck during the encoding process.

VTR Control 68 Argus Encoder Family Version 2.6 Installation and User Manual

Figure 2-7. VTR Control Window

DF (Drop Frame) – This box is checked when a drop frame VTR source is used. The DF box is unchecked when a non-drop frame VTR source is used. This process is automatic when the “Enable VTR Control” box is checked and a VTR is properly connected to the encoder. The encoder will sense if a drop frame source VTR is in use, and will check or clear the box accordingly. When a non-VTR source is used (or when the Enable VTR Control checkbox is cleared), the box can be manually checked or unchecked to insert DF or non-DF time code, respectively, into the MPEG stream GOP header. NOTE: A GOP time code adjustment flag can be set in the RegCtrlPnl application. See “Adjust Time Code (for Spectrum Users),” page 84 for a discussion of the setting.

VTR Control Chapter 2 — Using the Argus Encoder 69

Time Code Display – Displays the current time code presented by the VTR. Display is in hours:minutes:seconds:frames format. VTR Control Keys – Control buttons and sliders are as follows: Eject: Allows removal of the tape cassette from the VTR deck. Play: Begins playback of the tape. Stop: Halts playback of the tape. Pause: Pauses on the current frame. Playback can be restored by clicking again on Pause, or by clicking on Play. This feature allows tapes to be changed or repositioned in the midst of an encode. Multiple tapes can now be used in a single encode; simple “on-the-fly” cuts-only editing is also possible. Rev: Rewinds the tape until another control key is pressed or until the tape is rewound completely. Fwd: Fast-forwards the tape until another control key is pressed or until the tape reaches the end of its travel.

Figure 2-8. VTR Goto Button Dialog Window

Goto: Clicking the Goto button allows the user to cue the tape to a specific time code. A window (shown in Figure 2-8) will appear with three options: • Goto Time Code will instruct the VTR to seek the time code shown in the time code display. Direct entry of a desired time code is allowed. • Goto Mark In will instruct the VTR to cue at the time code shown in the Mark In field on the VTR Control window • Goto Mark Out will instruct the VTR to cue at the time code shown in the Mark Out field on the VTR Control window. Click the “X” (Close button) at the far right of this windows’s title bar to return to the VTR Control window. Note that this will not stop the VTR. To stop the VTR, click on the Stop button.

VTR Control 70 Argus Encoder Family Version 2.6 Installation and User Manual

Jog: Steps the VTR forward (+) or reverse (-) by single frames. Shuttle: Allows control of the VTR using an on-screen slider. Place the cursor on the slider button. By pressing and holding the left mouse button, the slider can be moved left and right. Left of center causes the VTR to move in reverse, while right of center moves the machine forward. The farther from center the slider moves, the greater the transport speed. Return the slider to center or click on the Stop button to stop the transport. Alternatively, by releasing the mouse button, the slider will return automatically to the center position and the VTR will stop. Mark In Capture Button – Click on the button to the right of the mark-in edit window (the button whose arrow points to the left) to capture the current time code from the tape deck and to place that time code in the mark-in edit window. Mark In (Edit window entry) – When the Enable VTR Control checkbox is checked, you may enter a value in the mark-in edit window to specify on what frame the encoded stream should start. The mark-in value is also used with the GOP-time-code adjustment feature. If you check the Adjust GOP Time Code field on the Argus tab of the RegCtrlPnl application (see Chapter 3), the mark-in field is used to time-stamp the first GOP header and to adjust all subsequent GOP headers. Starting with version 2.3 of the Argus software, the Adjust GOP Time Code feature may be selected in combination with the Mark-In field regardless of whether the Enable VTR Control checkbox is checked. Mark Out Capture Button – Click on the button to the right of the mark-out edit window (the button whose arrow points to the right) to capture the current time code from the tape deck and to place that time code in the mark-out edit window. Mark Out (Edit window entry) – When the Enable VTR Control checkbox is checked, you may enter a value in the mark-out edit window to specify where the encode should end. If you select a GOP structure that does not include B-frames, the encode will stop precisely on the mark-out that you select. If the GOP structure includes B-frames, the encode will end on or after the specified mark-out, possibly exceeding the mark-out by up to one frame (if the GOP structure is IBP…) or two frames (if the GOP structure is IBBP…). The mark-out value has no meaning at all if the Enable VTR Control checkbox is not checked. Duration (Edit window entry) – Enter a value in this edit window to specify the duration of the encode in hours:minutes:seconds:frames. If the Enable VTR Con- trol checkbox is not checked, entering the duration is the only method of controlling the stopping point of the encode. If VTR Control is enabled, though, you may enter either the duration or the mark-out. The Duration button is always inactive. Note that a duration of zero frames will instruct the Argus to encode indefinitely — until it receives a Stop command.

VTR Control Chapter 2 — Using the Argus Encoder 71

Time Code Grid – At the bottom of the VTR Control window is a matrix that displays the mark-in/mark-out/duration for each segment of a multi-segment (or scheduled pause/resume) encode. The top line displays the first segment. Note that when you highlight a filled line of the grid, its time codes appear in the time code edit fields in the upper right of the VTR Control window. Use the Tape ID field to indicate whether or not consecutive segments are encoded from the same tape. For example, if the first two segments both have a Tape ID of 1, the application assumes that the tape does not need to be changed between segments; therefore, it rolls to the next mark-in and resumes encoding without prompting the user. On the other hand, if the Tape ID of the first segment is 1, while the Tape ID of the second segment is 2, the application displays a message box between segments, prompting the user to click “OK” before resuming the encode. In an earlier software release (2.6.2), the scheduled pause/resume process was modified to support Dolby/AC-3 encoding. If you are planning to pause/resume while encoding AC-3 audio data, you must check the “Seamless Pause” option on the main page of the Registry-control panel (RegCtrlPnl) application in order to guarantee audio-video synchronization. In fact, even if you are NOT performing an AC-3 encode, you may enable the seamless pause/resume option to improve A/V synchronization. Refer to Chapter 3 for complete details on setting up the Registry Control Panel. NOTE: Do not set up a multi-segment or scheduled pause/resume encode if the multi-stream encode option is turned on. Finish – Click to apply changes and return to the EDL Editor window. Cancel – Click to dismiss the VTR Control window and discard all changes.

Encode Properties (Figure 2-9) The Encode Properties window is where settings are made and changed that control video, audio, and multiple, and file properties, among others. Video Properties Section Video Input – Selects the video source used by the encoder. Digital: SMPTE 2595M serial digital video. The CCIR-601 digital video format, an interface standard and tape format for high-end component digital video systems used in broadcast and production environments. Also referred to as SDI (Serial Digital Interface) video. Composite: Standard composite analog video format.

Encode Properties 72 Argus Encoder Family Version 2.6 Installation and User Manual

Figure 2-9. Encode Properties Window

Resolution – Selects the resolution of the picture to be encoded. Note that the first three full-resolution types run best at bit rates between 6 and 50 Mbps. You should use 720/VBI, 720, or 704 for the primary stream if you are creating secondary streams, too. 720/VBI: The vertical blanking interval (VBI) will be encoded, starting with line seven, as well as the viewable picture. The horizontal resolution is fixed at 720 pixels. The vertical resolution will be 512 lines (NTSC) or 608 lines (PAL).

Encode Properties Chapter 2 — Using the Argus Encoder 73

720: The picture resolution is 720 pixels by 480 lines (NTSC) or 576 lines (PAL). The VBI is not encoded. 704: The picture resolution is 704 pixels by 480 lines (NTSC) or 576 lines (PAL). The VBI is not encoded.

352 (half-res): The picture resolution is 352 pixels by 480 lines (NTSC) or 576 lines (PAL). Half-res generally runs best at video bit rates between 3 Mbps and 6 Mbps. Do not use this resolution if you are performing a multi-stream encode. 352 (SIF): The picture resolution is 352 pixels by 240 lines (NTSC) or 288 lines (PAL). The VBI is not encoded. SIF generally runs best at video bit rates between 0.5 Mbps and 3.0 Mbps. As the bit rate is decreased, the picture may become grainier or more blocky, especially for active scenes. Do not use this resolution if you are performing a multi-stream encode. Video Stream PID – Sets the PID number to be used for the video service when transport streams are specified. This value can be changed as needed. The default value of 512 (decimal) assures that the stream created does not use a PID that reserved by DVB for other uses. Frame Structure – Selects the number of B-frames used in the encoding process. IP: No B-frames are used. A group of pictures (GOP) will consist of an initial I-frame followed by P-frames. To encode all I-frames select IP-frame structure and an I-frame distance of one. Use I-frame only if it is important to end the encode precisely on the specified mark-out. IBP: A single B-frame is inserted between reference (I or P) frames. IBBP: Two B-frames are inserted. Use IBBP when the video quality of the stream is more important to you than is the frame-accuracy of the stopping point. I-Frame Distance – Selects the Group-of-Pictures (GOP) size to use, measured by number of pictures or frames included in the GOP. The options available vary with the frame structure selection. The recommended I-Frame distance is 12 or 15 when two B-frames are selected. Note that allowable I-Frame Distance settings vary with the setting of the Closed GOP Registry setting, as displayed on the top page of the RegCtrlPnl application. If you change the Closed GOP setting, you’ll note that the list of choices for I-Frame Distance changes the next time that you enter the Encode Properties Window.

Encode Properties 74 Argus Encoder Family Version 2.6 Installation and User Manual

Video Bit Rate – (In Mbps). Enter the desired bit rate for the video portion of the multiplexed stream. This is inactive when encoding transport streams, where the video bit rate is calculated from the Overall Mux Rate. The video bit rate must be between 0.5 Mbps and 15 Mbps for 4:2:0 mode encoding and between 3 Mbps and 50 Mbps for 4:2:2 mode. The ability to run at the full 50 Mbps depends on the system configuration. If multi-stream encoding is turned on, we recommend that you use a maximum video bit rate of 25 Mbps, perhaps less if all three low-bitrate streams are selected for creation. When variable bit rate encoding (VBR) is activated, the value in the video bit rate field represents the maximum video bit rate that the encoder will use. The maximum video bit rate must exceed the average video bit rate (set using RegCtrlPnl), but not by more than 2 or 3 Mbps. As with constant bit rate encoding, the video bit rate value is ignored for transport streams; the “overall mux rate” setting is used instead. Video Standard – NTSC or PAL. 4:2:2 / 4:2:0 – Only one of these buttons will be active. When 4:2:2 is selected, the Argus will encode the complete 4:2:2 color space. When 4:2:0 is selected, the color will be subsampled. This is the mode required for MPEG-2 Main Profile@Main Level (MP@ML) encoding.

Audio Properties Section Unless you have chosen the Spectrum multi-stream encoding option, the Argus encoder supports four channels (two stereo pairs) of audio. Except where noted, both channels use the same settings. Note that the Argus LC encoder board supports two channels of audio. Audio Input – Select analog or digital audio input. When two audio streams are enabled, they must both be of the same input type, e.g., both analog or both digital. Make certain to provide digital audio input if you select “digital” as the audio input source. Otherwise, the application will fail. Note that, if you have purchased the required hardware, you may also select embedded audio. If you do so, make certain to supply a digital audio source. Audio Mode – Select the type of audio encoding desired. Stereo: The left and right channels are processed independently of each other and delivered as a stereo signal. Joint Stereo: The left and right channels are processed together. The en-

Encode Properties Chapter 2 — Using the Argus Encoder 75

coding process takes advantage of the information that is common to both channels, providing high-quality audio at the lowest possible bit rates. Dual Mono: Two mono channels are processed independently. Mono (Left Ch.): A single mono channel is encoded and delivered to both outputs (left and right) by the decoder. Audio Bit Rate – Specify the compressed bit rate in bits per second. Valid bit rates are 32,000 to 192,000 for mono mode encoding. Valid bit rates for all other modes are 64,000 to 384,000 (80,000 is not valid). Free format is not supported. Some values are valid only with certain audio mode settings. In general, audio that is near-CD quality is achieved in joint stereo mode at an audio bit rate of 192,000 (the Vela default). See the following table for valid ISO/IEC MPEG audio bit rates. The application will allow some illegal combinations to be used. This should be avoided since many decoders will not accept these combinations.

Reference ISO/IEC 11172-3 MPEG-1 Audio Section 2.4.2.3 and 3-Annex B, Table 3-B.2, “Layer II Bit Allocation Tables.”

Sample Rate – Select the sample rate used to convert analog audio input to digital. The available options are 32,000, 44,100, and 48,000. The most common setting is 48,000. When digital audio is selected, this setting must match the actual sample rate of the source. When you turn on multi-stream encoding and select Ligos MPEG-1 as one of the secondary streams, the MPEG-1 stream will use the audio sample rate that you set for the primary MPEG-2 stream. Note that the Ligos MPEG-1 encoder plug-in does not support a sample rate of 32,000. Language – Sets a language indicator for transport streams. Default is English. Audio Stream PID – Sets the PID number to be used for the audio service when transport streams are specified. This value can be changed as needed. The default

Encode Properties Chapter 2 — Using the Argus Encoder 77

decimal values of 640 and 641 insure that the stream created does not use a PID that is reserved by DVB for other uses. Multiplex Properties Section Stream Format – Selects the methods to be used to combine the video and audio information into a single bitstream. System: This is the multiplex used for MPEG-1 and would normally be used only for SIF resolution. Program: The MPEG-2 multiplex format intended for storage applications. Transport: The MPEG-2 multiplex format intended for distribution of content over transmission networks. Overall Mux Rate – Sets the total value for the multiplexed stream when Trans- port is selected as the stream format. When Program or System is selected, the overall mux rate will be the sum of the video and audio components (plus over- head and padding). The overall mux rate must be between 3 Mbps and 15 Mbps for 4:2:0 mode encoding, and between 3 Mbps and 50 Mbps for 4:2:2 mode. The ability to run at the full 50 Mbps will depend on the system configuration and the encoding options you select. When the multi-stream encoding option is selected, the maximum guaranteed mux rate for the MPEG-2 stream is about 25 Mbps, less if more than one secondary stream is activated or if high resolutions or bit rates are applied to the secondary stream. When variable bit rate encoding (VBR) is activated, the maximum video bit rate for transport streams is derived from the overall mux rate setting. In such cases, the overall mux rate must be set in such a way that the derived maximum video bit rate exceeds the average bit rate that is set on RegCtrlPnl. File Properties Section Elem – Check this radio button to create an elementary file. Do not check this button if you are planning to do a multi-stream encode. The Video Elemen- tary and Audio Elementary checkboxes below it will become active: Video Elementary: Check this box to create a video elementary stream file during the encode process. Enter the desired file name in the file name box. Click the button to the right to browse the disk for existing files. Audio Elem (Chan 1): Check this box to create an audio elementary stream file for Channel 1 during the encode process. Enter the desired file name in the file name box. Click the button to the right to browse the disk for existing files. If this box is checked, the Video Elementary box must also be checked.

Audio Elem (Chan 2): Check this box to create an audio elementary stream file for Channel 2 during the encode process. Enter the desired file name in the file name box. Click the button to the right to browse the disk. If this box is checked, the Video Elementary box must also be checked. Mux – Check this radio button to create a multiplexed file. Note that you must create a multiplexed file if you are performing a multi-stream encode. The file name will be automatically created during the clip creation process. The name can be changed by typing in the file name box. Click the button to the right to browse the disk to find existing files. Do not check the Mux box if the Video Elementary box is checked. Other Properties The following miscellaneous properties can also be found on the Argus Encode Properties Window: Export – This is only used to provide backward compatibility with some older Argus systems and is not needed in recent versions of Argus encoders. Playback – Check this box to enable real-time decoding of the stream during the encoding process. This box must be checked if you are performing a multi- stream encode. Closed Captioning – Check this box to enable closed caption processing. When enabled, the closed caption data in line 21 is extracted from the video and carried as user data. Argus supports both the method defined by C-Cube Microsystems® for closed caption data, and the ATSC method for inserting closed caption data into an MPEG stream. The format that will be used is determined by a setting in the RegCtrlPnl application, which writes to the Windows Registry. See “Closed Caption Format,” page 83. Note that when you are encoding with 720/VBI resolution, the closed caption data on line 21 will be contained in the video stream; all other modes of closed caption processing are disabled with this resolution setting. ATSC closed captioning is not supported with SIF encodes. Note also that the closed caption data is not inserted into the secondary streams when multi-stream encoding in turned on. Inverse 3/2 – Not currently supported. Clip Name – Displays the name assigned to the clip. This is normally entered during the clip creation process, but can be changed by the user at any time. Note that changing the Clip Name from this window does not affect the file name. Clip Desc – Displays the description given to the clip. This is normally entered during the clip creation process, but can be changed by the user at any time.

VTR Control – Click this button to activate the VTR Control window (Figure 2-7). This allows the user to set the starting and ending points for an encode when a VTR is used. It also allows on-screen control of the VTR. See “VTR Control,” page 67. Finish – Click this to return to the EDL Editor window. All entries currently on screen will be saved. Cancel – Click this to return without changing the previous settings. Status Indicators Two status indicators are provided during the encoding process. A status bar is displayed on the bottom of the EDL screen, along with the percentage of the current encode that is complete. Also, an Event History window is displayed over the EDL window. Event History displays the sequence of events that occurs as the encoder is initialized. If desired, data shown in the Event History window can be saved as a text file. The resultant file may serve as a useful troubleshooting tool. If it displays an error or status code, that code can be found in the table in Appendix B. To save the file, use the File > Save As menu that appears at the top left corner of the window. Enter an appropriate file name and append a file extension of .txt. Configuring EDL Editor for a Multi-Stream Encode (This section is for Argus Spectrum users.) In order to generate two or more streams simultaneously (multi-stream encoding), you'll need to follow a few basic procedures before clicking the Start Encode button. First of all, make certain that a programmed Aladdin HASP® software protection key (“dongle”) hardware device is connected to the printer port of your encoder. You should have received the programmed HASP device with the delivery of your Argus Spectrum encoder (or with the upgrade software, version 2.6). Note that the HASP device is programmed to grant you permission to use only the secondary-stream encoding options that you purchased. For example, if you purchased only the Ligos MPEG-1 multi-stream option, the HASP device will allow you to configure and generate a Ligos GoMotion MPEG-1 secondary stream, but not a Real Media or Windows Media-formatted secondary stream. When you are configuring your primary stream for a multi-stream encoding session, there are several clip properties that you must set using the Encode Properties window of EDL Editor. In fact, if you'll be using your Argus Spectrum regularly to

Status Indicators 80 Argus Encoder Family Version 2.6 Installation and User Manual perform multi-stream encoding, it would be advisable to set up one or more templates configured specifically for multi-stream encoding. You might want to consult the “Quick Start” chapter and the “Template Management” section of this chapter for instructions on creating and loading templates. If you're configuring the primary clip for a multi-stream encoding session, be sure to follow these few rules: • Before starting the encode, first visit the RegCtrlPnl application, setting it up for the kind of multi-stream encode that you'd like to perform. Be sure to click the Apply button on RegCtrlPnl to save your settings to the Windows Registry before starting the encode. • In the video properties section, set the resolution to 720/VBI, to 720, or to 704. Do not use 352 (half-res) or 352 (SIF). • If you're creating a program stream, set the video bit rate at or below 25 Mbps. You may need to lower the bit rate of the primary stream even further if you are generating more than one secondary stream, if you are using full-SIF (as opposed to QSIF) resolution for your secondary stream, or if you are using a high bit rate or frame rate for your secondary stream. • In the audio properties section, disable the second audio stream, except when using the CineView Pro XL decoder. With any decoder other than the Pro XL, four-channel audio encoding is not supported when multi- stream encoding is enabled. • Set the audio sample rate of the audio streams to either 48,000 or 44,100 (without the commas) if your secondary stream will be in Ligos MPEG-1 format, as the Ligos MPEG-1 encoder will not accept a setting of 32,000. • If you are creating a transport stream, set the overall mux rate in the Multi- plex Properties section no higher than 25 Mbps. You may need to lower the mux rate of the primary stream even further if you are generating more than one secondary stream, if you are using full-SIF (as opposed to QSIF) resolution for your secondary stream, or if you are using a high bit rate or frame rate for your secondary stream. • In the File Properties section, click the Mux radio button (not the one marked Elem), then enter the full path name of the primary stream that you would like to create. Note that the names of all the secondary streams will be derived from the file name of the primary stream. • Always check the playback checkbox. Multi-stream encoding will not work if playback is turned off.

Configuring EDL Editor for a Multi-Stream Encode Chapter 3 The Argus Registry Control Panel Application (RegCtrlPnl)

Introduction The Argus Registry Control Panel Application (RegCtrlPnl), shown in Figures 3-1 through 3-6, serves two important purposes. First, it allows you to set advanced encoding stream parameters that do not appear on the EDL Editor property window. Secondly, but more importantly, for Spectrum users, it offers you a convenient way to configure the Argus Spectrum for multi-stream encoding. It performs both of these functions by storing encoding parameters in the Windows Registry. If you've used previous versions of Argus software, you'll notice that the RegCtrlPnl application replaces the CFInterface application as the management tool for advanced encoder settings. In fact, the RegCtrlPnl “Argus” property page holds most of the settings that were previously listed on CF Interface. When you click the Apply button, RegCtrlPnl stores its values in an Argus-specific table in the Windows Registry, eliminating the need for a configuration file. Before cueing for each encode, EDL Editor reads the current encoder settings from the Windows Registry, then applies them when it sets up for the next encode. All of the other settings for the clip are read from the database. To activate RegCtrlPnl, double-click the desktop icon labeled “RegCtrlPnl.” If for some reason that icon does not appear on your desktop, look for it in the folder C:\Program Files\Vela Research\Argus. Once the interface is activated, the window appears. Each of the features on the Argus tab represents an advanced MPEG property, defined and described below. Once you are satisfied with all of the field settings, click on the Apply button. Your modifications will take effect the next time that a clip is cued. You need not exit and restart the EDL Editor. Argus 422/420/LC Encoding Parameters The Registry Control Panel Application (RegCtrlPnl), shown in Figure 3-1, provides for the setting of advanced MPEG encoding features through a simple Windows interface. Generally, there are a few parameters that are rarely changed from one encoding session to another. These settings are found on the Argus property page, which appears in full view when the RegCtrlPnl pops up. Each of the features on the Argus property page (shown in Figure 3-1) is defined below. The Spectrum RegCtrlPnl property page is similar and appears in Figure 3-2.

Introduction 82 Argus Encoder Family Version 2.6 Installation and User Manual

Figure 3-1. Argus Registry Control Panel Application Window

Video Stream ID (Vid Strm ID) – (Default: 0) The video stream ID is used in the MPEG PES header to identify the video stream. The number, which may range in value from 0 to 15, is unique among the IDs of all of the video streams included in the muxed file. Since we generate only one video stream per encode, this setting should, in most cases, be left at 0. Audio Stream ID 1 (Aud Strm ID 1) – (Default: 0) This audio stream ID is used in the MPEG PES header to identify the audio stream. This number, which may range in value from 0 to 31, is unique among the IDs of all of the audio streams included in the muxed file. Normally you should leave this setting at 0. Audio Stream ID 2 (Aud Strm ID 2) – (Default: 1) The Argus encoder offers the opportunity to encode up to two audio streams at once. In such cases, Aud Strm ID 1 should be set to 0, and Aud Strm ID 2 should be set to 1. If only one audio stream is being encoded, this setting is ignored. Spectrum users should note that the second audio stream must be set to inactive if you are performing a multi- stream encode, except when using the CineView Pro XL decoder.

Argus 422/420/LC Encoding Parameters Chapter 3 — The Argus Registry Control Panel Application (RegCtrlPnl) 83

Headroom – (Default: 18) The audio headroom may be set to 18 or 20. Reference Level – (Default: +4 dB) Adjust the volume of the audio by setting the reference level to +4 dB, 0 dB, or -10 db. DC Precision – This setting selects the number of bits used to represent the DC coefficients for intra-coded portions of pictures. The MPEG specifications allow settings of 8, 9, and 10 bits. The IBM encoder allows an additional non-standard setting of 11. If (and only if) the encode is a SIF encode, the DC Precision setting must be 8; in fact, for SIF encodes, the Argus encoder ignores the Registry setting of DC Precision and forces the setting to 8. Aspect Ratio – (Default: 4x3) This setting sets a field in the encoded stream indicating the aspect ratio of the source material. Possible values are square, 4x3, 16x9, and 2.21x1. Closed Caption Format – (Default: C-Cube) This setting determines the format in which the closed caption data will be stored in the stream (only if the closed caption flag is turned on for the clip). Possible values: Standard C-Cube: C-Cube-specified format for field-1 closed captioning. Frame-order of closed caption data is not reordered when there are B- frames present in the GOP. Custom C-Cube: A custom version of the C-Cube format for field-1 closed captioning. Frame-order of closed caption data is reordered when there are B-frames present in the GOP. Standard ATSC: Standard ATSC format for field 1 and field 2 closed captioning. Frame-order of closed caption data is reordered when there are B-frames present in the GOP. Custom ATSC: A modified, non-standard version of ATSC closed captioning in which the frame-order of closed caption data is not reordered when there are B-frames present. Average VBR Bit Rate – This value represents the average video bit rate that the encoder will attempt to achieve when variable bit rate encoding is turned on. The average bit rate must be less than the maximum bit rate, which is specified (for all stream types other than transport) in the “Video bit rate” field of the Encode Properties window of EDL Editor. For transport streams, the maximum video bit rate is derived from the “Overall mux rate” setting, also located on the EDL Editor Encode Properties window. The difference between the average and the maximum VBR bit rates should not exceed 25% of the maximum video bit rate.

Argus 422/420/LC Encoding Parameters 84 Argus Encoder Family Version 2.6 Installation and User Manual

First Video Line – This field determines which line of video will be the starting line of each encoded picture when VBI-mode encoding is not selected. Normally the first video line is set to 22. Only under special conditions should you change this value to anything other than 22. For example, if you must include closed captioning but cannot use the VBI-mode option and cannot allow the encoder to place the closed-caption data in the user-data field, then you may set the first video line to 21; doing so includes line 21, with its closed caption data, among the 480 encoded lines. Non-Linear Quantization – (Default: ON) If this flag is checked, the non-linear quantizer table is loaded. This value is normally turned on, especially for low-bit rate streams. Concealment Vectors – (Default: OFF) Allowed settings are ON (checked) and OFF (unchecked). ON instructs the encoder to include in the stream concealment vectors that the decoder can use if the transmission is noisy. Never use this setting for SIF encodes, or the encoded stream will break up. Intra Tables – (Default: OFF) Checking this field selects the alternate coefficient table (appropriate for MPEG-2 compression). In practice, this setting is usually ignored by the encoder, which sets the value appropriately based on the MPEG compression-level specified. Closed GOP – (Default: OFF) This setting indicates the nature of the predictions used in the B-pictures (if any) immediately following the first I-frame in the GOP. If the checkbox is checked (ON), the B-pictures will use only backward prediction. Setting the flag ON is useful if post-encode editing is anticipated. Note that if you change this setting AFTER a clip with B-frames is saved or encoded, you must revisit and save the clip's EDL Editor property sheet to readjust the GOP size of the clip. Otherwise, the result could be a corrupted encoded stream. Adjust Time Code – (Default: OFF) If this check box is checked, the GOP time code will reflect the mark-in. Normally the time code in the first GOP header is set to 0. If this flag is turned on, the GOP time code stored in the first GOP header will be equal to the mark-in specified in the VTR window, and the time code in each subsequent GOP header will be adjusted by the value of the mark-in. Adjust Time Code (for Spectrum Users) – (Default: OFF) If this checkbox is checked (ON), the GOP time code of the primary stream will reflect the mark- in. Normally the time code in the first GOP header is set to 0. If this parameter is turned ON, the GOP time code stored in the first GOP header will be equal to the mark-in specified in the VTR window, and the time code in each subsequent GOP header will be adjusted by the value of the mark-in. If you are creating a Ligos secondary stream. the time code in the Ligos GOP headers can

Argus 422/420/LC Encoding Parameters Chapter 3 — The Argus Registry Control Panel Application (RegCtrlPnl) 85

be similarly adjusted by checking the Adjust GOP Time Code checkbox on the Ligos property page. Drop Frame – (Default: 1) This value is only a suggestion to EDL Editor that the source material is recorded as drop-frame NTSC. If VTR control is turned on, EDL Editor reads the drop-frame value from the tape deck, overriding the value set in the Registry by RegCtrlPnl. Original – Check this box to set the “original” bit in the audio stream, indicating that the bitstream is an original (not a copy). Copyright – Check this box to set the “copyright” bit in the audio stream, indicating that there is a copyright on the audio bitstream. Optimize File Writes – Check this box if you want to use the most efficient method of writing the encoded stream to file (especially useful for high-bitrate encodes). If optimized writes fail on your system (which may happen if you are writing to a mapped drive), uncheck this checkbox to use standard file-writes. Note that one side-effect of optimized writes is that the stored file appears to be of size 0 until the encode is finished and the file is closed. If your application requires that the file size increase as the encode progresses, uncheck the Optimize File Writes check box. VBR Mode – (Default: OFF) Check this box to turn on variable bit rate encoding. When VBR is activated, the encoder adjusts the bit rate during the course of the encoding process, increasing the bit rate with difficult-to-encode scenes to achieve better quality. If you check the VBR Mode checkbox, you must also enter an average bit rate in the “Avg VBR BR” edit box on the same property page. To specify the maximum bit rate that should be used for elementary, system or program streams., enter that value in the “Video bit rate” field of the Encode Proper- ties window of EDL Editor. For transport streams, set the overall mux rate (also found on the Encode Properties window of EDL Editor) to a value slightly greater than the maximum video bit rate that you'd like to achieve. Seamless Pause – Check this box if you are planning to pause/resume while encoding Dolby/AC-3 audio data to guarantee audio/video synchronization. In fact, even if you are not performing an AC-3 encode, you may enable this option to gain improved A/V synchronization. AC-3 PID – Not used unless the Vela Dolby Digital/AC-3 Encoder hardware/software accessory package is purchased and installed. Complete instructions for its use are included with the product. OK – Click to save your settings to the Windows Registry and dismiss the window. Do this before starting the encode.

Argus 422/420/LC Encoding Parameters 86 Argus Encoder Family Version 2.6 Installation and User Manual

Cancel – Click this to dismiss the window without changing the previous settings. Apply – Click to save your settings to the Windows Registry. Do this before starting the encode. Argus Spectrum Encoding Parameters

The Argus Spectrum Property Page The Spectrum property page differs from that of other Argus encoders in that tabs are provided for various secondary streams the user may desire to create. Tabs for each secondary stream plug-in that was purchased will show up along the top of the window. If you have not purchased a particular plug-in, its tab will not appear. However, the basic “Argus” tab property page parameters are similar to those of the Argus 4:2:2/4:2:0 / LC property page shown in Figure 3-1 (and defined on page 81), and can be set similarly, except where noted.

Figure 3-2. Spectrum Registry Control Panel Application Window

Argus Spectrum Encoding Parameters Chapter 3 — The Argus Registry Control Panel Application (RegCtrlPnl) 87

Setting Multi-Stream Encoding Parameters In order to perform a multi-stream encode of any kind, you'll need to follow a few basic procedures before clicking the Start Encode button on EDL Editor. First of all, make certain that you use EDL Editor to configure the clip (primary stream) according to the rules for multi-stream encoding listed at the very end of Chapter 2. To configure the secondary stream(s), you will need to visit the remaining property sheets on RegCtrlPnl, clicking Apply to save the settings to the Windows Registry before starting the multi-stream encode. The remainder of this chapter is dedicated to describing fully the RegCtrlPnl property pages related to multi-stream encoding. Note that the version of RegCtr- lPnl that pops up on your encoder may look different than the figures shown on the next few pages. The RegCtrlPnl application configures itself to display only the property pages that apply to the multi-stream encoding software that is installed on the system where it is running. The Multi-Stream Encode Property Page Click the Multi-Encode tab to display the property page that holds settings that are common to all of the secondary streams, whether they are in Ligos MPEG-1, Real Media, or Windows Media format. See Figure 3-3 for an example of the Multi-Encode property page.

Argus Spectrum Encoding Parameters 88 Argus Encoder Family Version 2.6 Installation and User Manual

Figure 3-3. Spectrum Multi-Encode Property Page

Actually, there is only one secondary-stream property exposed on this page: the resolution type. Currently, the Argus Spectrum allows you to set the secondary streams to use only SIF or QSIF resolutions. Those resolutions are listed in the following table.

Vertical Resolution Vertical Resolution Resolution Type Horizontal Resolution (NTSC) (PAL)

QSIF 176 120 144 SIF 352 240 288

Table 3-1. Secondary Stream Resolution Table Note that generating a secondary stream with SIF resolutions takes more processing power than generating a stream with QSIF resolutions. If you use SIF resolutions, you may need to decrease the video bit rate or mux rate of your primary stream.

Argus Spectrum Encoding Parameters Chapter 3 — The Argus Registry Control Panel Application (RegCtrlPnl) 89

The Ligos (MPEG-1) Property Page If you'd like to create an MPEG-1 secondary stream during your multi-encoding session, click on the Ligos tab to bring up its property page (Figure 3-4). The Ligos MPEG-1 secondary stream will match the MPEG-2 primary stream frame- by-frame until one frame before the end (the Ligos stream ends one frame before the primary stream does). As mentioned earlier, this tab will appear on your RegCtrlPnl application only if the proprietary Ligos GoMotion® MPEG-1 software is installed on your system.

Figure 3-4. Ligos Stream Property Page These are the fields that appear on the Ligos Property Page: Ligos Enabled – Check this box to instruct the encoder to generate a Ligos MPEG-1 secondary stream as well as an MPEG-2 primary stream. The Ligos MPEG-1 stream can be enabled in combination with other secondary-stream formats, but enabling more than one secondary stream at a time will increase the CPU usage and may necessitate lowering the bit rate of the primary stream. Audio Bit Rate – Select an audio bit rate that one that you would like to use for your MPEG-1 stream. “Audio Properties Section,” page 74, for more information about audio bit rates, including a list of valid audio bit rate settings.

Argus Spectrum Encoding Parameters 90 Argus Encoder Family Version 2.6 Installation and User Manual

Video Bit Rate – Set the video bit rate to a value between 512,000 and 3,000,000 (don't include the commas). Note that the lower bit rate will demand less CPU usage and less storage, but the higher bit rate will deliver better video quality. Adjust GOP Time Code – Check this box to adjust the GOP header time code of the MPEG-1 Ligos stream to reflect the Mark-In set on the VTR Control window of EDL Editor. When you select this option, the time codes displayed on the CineViewPro GUI as the clip is playing back match the time code on the source tape. This feature is available only if VTR Control is enabled for the clip being encoded (“VTR Control,” page 67). To similarly adjust the GOP header time codes of the primary stream, you'll need to set the Adjust GOP Time Code checkbox on the Argus property page of this application. File Name – Do not fill in this field. When you encode using EDL Editor, the EDL Editor application creates the file name of the Ligos MPEG-1 stream by replacing the “.mpg” extension of the mux file name (of the primary stream) with the “.mpe” extension. For example, if your primary stream is stored in D:\MPEG- FILES\test.mpg, the Ligos stream will be stored in D:\MPEGFILES\test.mpe. Default – Click this button to restore the fields to their default settings. The Real Media Property Page If you'd like to create a secondary stream in Real Media format during your multi- encoding session, click on the Real tab and fill in the settings described below. Note that the Real tab will appear on your RegCtrlPnl only if the proprietary Real (G2) software is installed on your system. See Figure 3-5. Real Encode Enabled – Check this box to instruct the encoder to generate Real Media secondary stream as well as an MPEG-2 primary stream. The Real Media stream can be enabled in combination with other secondary-stream formats, but enabling more than one secondary stream at a time will increase the CPU usage and may necessitate lowering the bit rate of the primary stream. Title – Enter a title for the Real Media secondary stream. This title is informational only, used by the Real Media player to describe the stream. Author – Enter the author of the Real Media secondary stream. This optional field is informational only. Audio Format – Select Voice, Voice Background, Music, or Music Stereo to identify the type of audio that you are encoding. Video Quality – Select Normal Motion, Smooth Motion, Sharp Video, or Slide Show to identify the quality of video that you would like to achieve. Of course,

Argus Spectrum Encoding Parameters Chapter 3 — The Argus Registry Control Panel Application (RegCtrlPnl) 91

Figure 3-5. Real Media Stream Property Page as you increase the video quality, you also increase the CPU usage, perhaps necessitating a reduction in the bit rate of the primary stream. Target Audience – From among the six checkboxes, select the one that best describes the data transmission rate that you typically use. You may want to sample each of the six settings, reviewing the resulting Real streams to determine which one best meets your needs. Real Preview Window – Select this checkbox to pop up a Real Media playback window on your screen while you are encoding. This allows for confidence monitoring of the Real Media encoding process. However, it does consume extra CPU cycles. File – Check this box to store the Real Media stream in a file on your encoder's local disk drive. Do not fill in the name of the locally stored file, since EDL Editor will create this file name for you. If just substitutes the “.rm” file extension for the “.mpg” extension of the file name of your primary stream. For example, if your primary stream is stored in D:\MPEGFILES\test.mpg, the Real Media file will be stored in D:\MPEGFILES\test.rm. Server – Click this box to instruct the Real Media encoding application to stream the encoded secondary stream to a remote server. Fill in the name of the

Argus Spectrum Encoding Parameters 92 Argus Encoder Family Version 2.6 Installation and User Manual server in the adjacent edit box. Provide the name of the remotely stored file in the File Name text edit field. Note that the remote machine receiving the file must be configured as a Real server. Default – Click this button to restore the fields to their default settings. The Windows Media Format Property Page If you want at least one of your secondary streams to be in Windows Media Format (WMF, previously known as ASF) click the Windows Media Video tab, then check the Windows Media Video Enabled checkbox. When this feature is activated, your encoding session will result in a primary MPEG-2 stream and a secondary stream in WMV format. Note that the Windows Media Video tab will appear on your RegCtrlPnl only if the proprietary Windows Media encoding software is installed on your system.

Figure 3-6. Windows Media Stream Property Page

Windows Media Video Enabled – Check this box to instruct the encoder to generate a Windows Media-formatted secondary stream as well as an MPEG-2

Argus Spectrum Encoding Parameters Chapter 3 — The Argus Registry Control Panel Application (RegCtrlPnl) 93 primary stream. The Windows Media stream can be enabled in combination with other secondary-stream formats, but enabling more than one secondary stream at a time will increase the CPU usage and may necessitate lowering the bit rate of the primary stream. Video Bit Rate – Select a video bit rate setting from one of the 10 selections on the Video Bit Rate slider bar. Video Codec – Select the video codec desired, choosing one of the following: ISO MPEG-4, version 1; Microsoft MPEG-4, version 3; Windows Media Video, version 7, 8, or 9; or Windows Media Screen version 9. Use the Windows Media Video version 9 codec for best quality at the lowest bandwidth. Choose the Windows Media Screen version 7 codec for creating streams that have little or no motion, such as slide presentations. Mute – Check the mute button to disable audio in the WMF-formatted stream. Audio Codec – Windows Media Audio version 9, Windows Media Audio 9 Voice, or Spiro Labs ACECP (voice only). Choose the Spiro lab codec if the clip you are encoding contains mostly voice and you wish to conserve bandwidth. Audio Codec Format – String represents the audio codec format string to use for the corresponding audio codec. See the following table for valid string values.

NOTE: The creation of secondary streams is a CPU-intensive process. The maximum achievable audio / video quality and data rate for each of the secondary streams (Ligos, RealNetworks, or Windows Media Format) are directly affected by the CPU bandwidth and by the number of tasks that the encoder is being asked to perform.

Appendix B Troubleshooting the Argus

Troubleshooting Procedures Use this guide to help determine and resolve installation or operational problems with your Vela Argus encoder. Password is unknown — To login, press the Control (Ctrl), Alternate (Alt), and Delete (Del) keys together. When the “Logon Information” dialog box appears, type: Username: ARGUS Password: mpeg-2 Click the OK button in the Login dialog box, or press Enter. Digital serial audio is not working — Assure that the digital audio input is connected to the AES/EBU input. If both audio channels are connected, digital audio must be connected to both AES/EBU inputs. Be sure the sample rate selected for the audio processing matches the audio sample rate of the source. Professional video equipment will normally use a sample rate of 48 kHz. Digital video is not working — It is critical when encoding a clip that specifies a digital video input that the a digital video signal be connected to the digital video BNC connector of the encoder board. If the encoder hardware does not detect a signal the clip will fail. Real-time playback not working — Be sure the real-time output cable is connected to the video out connector on the decoder board, and be sure the Playback checkbox on Encode Properties is selected. Check the HKEY_CURRENT_USER\ Software\Vela Research\Broadcast Argus\EncoderConfig Registry table to make sure that the “Decoder Installed” key is set to 1. Cannot open file — Make sure a filename has been entered in the “filename” box and that the specified directory exists. Also make certain that your hard drive has sufficient room to hold the stream. VTR Control is not working — The protocol (level) converter and cable might not be connected to the proper COM port. Make sure that the VTR deck is switched to “Remote.” Ensure that the VTR Enabled checkbox is checked. Ensure that the proper COM port is indicated in the VTR control. If the VTR control cannot establish a connection over the indicated COM port, the time code display will blink “Error” or will display “ – – : – – : – – : – – ”.

Troubleshooting Procedures 106 Argus Encoder Family Version 2.6 Installation and User Manual

VTR Control is not enabled; the Start Encode dialog box does not get displayed on top if another window is active. — The dialog box gets displayed in front of EDL Editor, but not in front of the Encoder window, if the user has moved the Encoder window (or any other window) in front of the EDL Editor. By keeping the EDL Editor completely visible, there should be no problem. Mark-in/Mark-out/Duration fields don’t work as expected. — The easiest way to change the values in the time code fields is in overwrite mode. EDL Editor is open and a “Data source not found” error message appears. — The ODBC driver may need to be replaced or reinstalled. Go to the Start menu, select Settings > Control Panel. If you are running Windows 2000, do the following step: 1. In the Control Panel, double-click on Administrative Tools > Data Source (ODBC) icon. If you are running Windows NT, do this step: 1. In the Control Panel, double-click on the ODBC icon. Steps 2–6 that follow apply to both operating systems. 2. You should see a System DSN tab on the dialog box. Select this tab, then click the Add button. “Microsoft Access Driver” should be highlighted. Click OK. 3. Type in “BroadcastArgus” (without the quotes and with no space between the two words) in the Data Source name field. 4. Click on the Database: Select button. 5. Select the C:\ VELA_DB\ BArgus.mdb file and press OK. 6. Click OK and then click Close. Your EDL Editor should now launch without problems. The following error message is displayed when starting EDL Editor: “The ODBC Resource DLL (C:\WINNT\System32\odbccint.dll) is a different version than the ODBC driver manager …” — This indicates that some system files are not correct, possibly due to system updates other than the Argus software. Click on the Cancel button. You will probably receive additional error messages. Click OK for each. Exit the EDL by clicking on the “X” on the top right corner. To correct this error, the proper ODBC (data base) files must be installed. The installation for these is provided in the System folder of the Argus distribution CD-ROM. Open that folder and double-click on the file mdac_typ.exe. This will launch the installation program for these files. You will see the following dialog boxes during this process:

Troubleshooting Procedures Appendix B — Troubleshooting the Argus 107

• End User License Agreement: click OK • Microsoft Data Access Components Setup: click continue • Type of Installation: click Complete When the installation is complete: click OK. The system will be rebooted. You can now run the EDL without the error messages. Filter Manager Error/Status Codes If your Argus encoder fails, check the Event History window for negative error codes. If you find one, you can look it up in the following table. NOTE 1: There are six error codes that are reported by the video encoder chip and passed unaltered through Filter Manager. Unfortunately, these six error codes conflict with identically numbered errors generated by Filter Manager itself. Although it is true that these six error codes do not uniquely identify a single specific Argus error condition, in most cases the error condition can be identified by the context in which it is reported. The error codes reported by the encoder chip are identified as such in the Comments section of the Error/Status Codes table that follows. NOTE 2: If you abort an encode or shut down your application without cleanly ending an encode, you must make certain that CVProServer and MemMgrServer have both been terminated before you restart the application. You can terminate these services using Task Manager.
