(A/V Codecs) REDCODE RAW (.R3D) ARRIRAW
What is a Codec? Codec is a portmanteau of either "Compressor-Decompressor" or "Coder-Decoder," which describes a device or program capable of performing transformations on a data stream or signal. Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing. Codecs are often used in videoconferencing and streaming media solutions. A video codec converts analog video signals from a video camera into digital signals for transmission. It then converts the digital signals back to analog for display. An audio codec converts analog audio signals from a microphone into digital signals for transmission. It then converts the digital signals back to analog for playing. The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream. Most codecs are lossy, in order to get a reasonably small file size. There are lossless codecs as well, but for most purposes the almost imperceptible increase in quality is not worth the considerable increase in data size. The main exception is if the data will undergo more processing in the future, in which case the repeated lossy encoding would damage the eventual quality too much. Many multimedia data streams need to contain both audio and video data, and often some form of metadata that permits synchronization of the audio and video. Each of these three streams may be handled by different programs, processes, or hardware; but for the multimedia data stream to be useful in stored or transmitted form, they must be encapsulated together in a container format. -

DIGITAL Media Players Have MEDIA Evolved to Provide PLAYERS a Wide Range of Applications and Uses
2011-2012 Texas 4-H Study Guide - Additional Resources DigitalDIGITAL media players have MEDIA evolved to provide PLAYERS a wide range of applications and uses. They come in a range of shapes and sizes, use different types of memory, and support a variety of file formats. In addition, digital media players interface differently with computers as well as the user. Consideration of these variables is the key in selecting the best digital media player. In this case, one size does not fit all. This guide is intended to provide you, the consumer, with information that will assist you in making the best choice. Key Terms • Digital Media Player – a portable consumer electronic device that is capable of storing and playing digital media. The data is typically stored on a hard drive, microdrive, or flash memory. • Data – information that may take the form of audio, music, images, video, photos, and other types of computer files that are stored electronically in order to be recalled by a digital media player or computer • Flash Memory – a memory chip that stores data and is solid-state (no moving parts) which makes it much less likely to fail. It is generally very small (postage stamp) making it lightweight and requires very little power. • Hard Drive – a type of data storage consisting of a collection of spinning platters and a roving head that reads data that is magnetically imprinted on the platters. They hold large amounts of data useful in storing large quantities of music, video, audio, photos, files, and other data. • Audio Format – the file format in which music or audio is available for use on the digital media player. -

Getting Started Guide Windows Media Player 11
Getting Started Guide Windows Media Player 11 Version 2.1 Transfering songs to your WALKMAN using Windows Media Player 11 About this tutorial You can use Windows Media Player 11 to rip songs from your CDs to your computer so that they become files on your computer. After that, you can sync the ripped songs with your WALKMAN; burn a customized music CD for enjoying at a party or in your car; or play the songs anytime from your computer without the hassle of having to find the original CD. Getting Started There are three main tasks you need to learn before you can play your music on your Walkman. First learn how to rip (copy) music from a CD on to your computer that you want to sync (copy) to your Walkman. Second, learn how to connect to your Walkman, and third, sync (copy) the songs on your computer that you want to listen to on the Walkman. Step 1: Ripping (copying) songs from a CD to your computer 1. Start Windows Media Player. On the taskbar at the bottom of your screen, click Start, and then click All Programs. Next, click on Windows Media Player from the list of programs that appears. 2. Insert an audio CD into the CD drive, and then click the Rip tab, as shown in the following screen shot. Note : When you are connected to the Internet, Windows Media Player attempts to retrieve media information such as the album and artist name about the tracks being ripped from a Windows Media database that is maintained by Microsoft.
