Abstract

MPEG is the video compression technique created by the Moving Picture Expert Group, a working committee which developed a technique for encoding video and audio streams into a digital format capable of playback by CD-ROM drive (video CD). The technique overcomes the problem inherent in CD-ROM technology, of the massive storage requirement of video signals and the high information transfer speeds necessary. Describes how MPEG coding works and reports video and audio rates for MPEG, compared with other standards
