sr1500-1250_sales_guide.qxd 10.1.27 7:40 PM Page 1 Glossary Blu-ray Disc™ HDD Recorder G1080i GHDMI (High-definition Multimedia Interface) (500GB HDD) In a single high-definition image, 1080 (1125) alternating scan lines pass every 1/60th (NTSC) Established in Dec. 2002, HDMI is an interface for digital electronic equipment that acts as the SR-HD1500 or 1/50th (PAL) of a second to create an interlace image. And because 1080i (1125i) more than connection standard between PCs and displays. It transmits uncompressed HD digital audio doubles the current scan lines of 480i (525i) found on television broadcasts, it helps to ensure and video signals on a single cable without distortion. The DVI interface was its predecessor, (250GB HDD) that details are much clearer, enabling the creation of more realistic and richer images. and HDMI has been enhanced for AV equipment by adding functions such as audio SR-HD1250 transmission capability, copy protection of digital content and other intellectual properties, as well as the ability to transfer color-variation information. GAVCHD (Advanced Video Codec High Definition) AVCHD is an acronym for Advanced Video Codec High Definition, and it is the format for HD GMPEG-2 (Moving Picture Experts Group 2) camcorders used to record and playback high-definition video images. AVCHD uses the MPEG-2 is a standard for efficient data compression and color video expansion that is widely H.264/MPEG-4 AVC compression format for video to enable highly efficient encoding, the Dolby used for media such as DVDs and satellite-based digital broadcastings.

Digital Video Quality Handbook (May 2013
Digital Video Quality Handbook May 2013 This page intentionally left blank. Executive Summary Under the direction of the Department of Homeland Security (DHS) Science and Technology Directorate (S&T), First Responders Group (FRG), Office for Interoperability and Compatibility (OIC), the Johns Hopkins University Applied Physics Laboratory (JHU/APL), worked with the Security Industry Association (including Steve Surfaro) and members of the Video Quality in Public Safety (VQiPS) Working Group to develop the May 2013 Video Quality Handbook. This document provides voluntary guidance for providing levels of video quality in public safety applications for network video surveillance. Several video surveillance use cases are presented to help illustrate how to relate video component and system performance to the intended application of video surveillance, while meeting the basic requirements of federal, state, tribal and local government authorities. Characteristics of video surveillance equipment are described in terms of how they may influence the design of video surveillance systems. In order for the video surveillance system to meet the needs of the user, the technology provider must consider the following factors that impact video quality: 1) Device categories; 2) Component and system performance level; 3) Verification of intended use; 4) Component and system performance specification; and 5) Best fit and link to use case(s). An appendix is also provided that presents content related to topics not covered in the original document (especially information related to video standards) and to update the material as needed to reflect innovation and changes in the video environment. The emphasis is on the implications of digital video data being exchanged across networks with large numbers of components or participants. -
Digital Video Recording
Digital Video Recording Five general principles for better video: Always use a tripod — always. Use good microphones and check your audio levels. Be aware of lighting and seek more light. Use the “rule of thirds” to frame your subject. Make pan/tilt movements slowly and deliberately. Don’t shoot directly against a wall. Label your recordings. Tripods An inexpensive tripod is markedly better than shooting by hand. Use a tripod that is easy to level (look for ones with a leveling bubble) and use it for every shot. Audio Remember that this is an audiovisual medium! Use an external microphone when you are recording, not the built-in video recorder microphone. Studies have shown that viewers who watch video with poor audio quality will actually perceive the image as more inferior than it actually is, so good sound is crucial. The camera will automatically disable built-in microphones when you plug in an external. There are several choices for microphones. Microphones There are several types of microphones to choose from: Omnidirectional Unidirectional Lavalier Shotgun Handheld In choosing microphones you will need to make a decision to use a wired or a wireless system. Hardwired systems are inexpensive and dependable. Just plug one end of the cord into the microphone and the other into the recording device. Limitations of wired systems: . Dragging the cord around on the floor causes it to accumulate dirt, which could result in equipment damage or signal distortion. Hiding the wiring when recording can be problematic. You may pick up a low hum if you inadvertently run audio wiring in a parallel path with electrical wiring. -

Video Terminology Video Standards Progressive Vs
VIDEO TERMINOLOGY VIDEO STANDARDS 1. NTSC - 525 Scanlines/frame rate - 30fps North & Central America, Phillipines & Taiwan . NTSC J - Japan has a darker black 2. PAL - 625 scanlines 25 fps Europe, Scandinavia parts of Asia, Pacific & South Africa. PAL in Brazil is 30fps and PAL colours 3. SECAM France Russia Middle East and North Africa PROGRESSIVE VS INTERLACED VIDEO All computer monitors use a progressive scan - each scan line in sequence. Interlacing is only for CRT monitors. LCD monitors work totally differently - no need to worry about. Interlacing is for broadcast TV. Every other line displayed alternatively. FRAME RATES As we transition from analogue video to digitla video. Film is 24 fps, PAL video 25 fps. NTSC 30fps. Actually film and NTSC are slightly different but we don't need to worry about that for now. IMAGE SIZE All video is shot at 72 px/inch - DV NTSC - 720 x 480 (SD is 720 x 486) DV PAL - 720 x 576 (SD PAL is 720 x 576) HD comes in both progressive and interlaced. HD480i is usual broadcast TV 480p is 480 progressive. 720i is 720 interlaced 720p is progressive. 720 means 720 vertical lines 1080 is 1080 vertical lines. 1080i is most popular. 720p is 1280 x 720, HD 1080 is 1920x1080px. All HD formats are 16:9 aspect ratio. Traditional TV is 4:3 aspect ratio. HDV is 1440 x 1080. New format - is it the new HD version of DV? Cameras like the Sony and JVC make minor alterations to this format when shooting In summary HD 1080i = 1920 x 1080 HD 720p = 1280 x 720 Traditional = 720 x 480 (NTSC) 720 x 576 (PAL) VIDEO OUTPUTS Analog Composite, S-Video, Component in increasing quality. -
