The MPEG-1 Codec
The MPEG-1 codec is still used for some legacy applications but the capabilities of MPEG-2 and MPEG-4 provide better compression ratios and more sophisticated coding techniques. New projects are unlikely to be based on MPEG-1. This was a popular codec when deploying video on CD-ROMs and is also used in games design.
10.2 How It Is Done in MPEG-1
The simplest of the MPEG video-compression formats is the best place to start. The others are all based on this model and just add some enhancements. The inventors of the MPEG coding schemes considered concepts of frames and luma plus chroma representation and worked out some techniques for compressing video that provide the most flexible but compact system.
