MPEG

Computer

1. (Moving Picture Experts Group) The committee—a joint CCITT and ISO/IEC group—that works on the storage and transmission of moving images, especially video images, and developed the ISO 11172 standard (see def. 2).
2. The ISO/IEC 11172 standard, Compression of Moving Images with Audio and Timing Data. It is designed to reduce the amount of information needed to describe a video sequence, so reducing either the bandwidth required to transmit the sequence or the amount of memory needed to store it. The MPEG-1 standard is for digital storage media such as CD-ROM; the MPEG-2 standard is for high-quality video transmission such as digital broadcasting.
The MPEG video-compression algorithm relies on two basic techniques: block-based motion compensation for the reduction of temporal redundancy (effectively recognizing the similarity between adjacent frames in the video) and DCT (discrete cosine transform) compression for the reduction of spatial redundancy (see JPEG).

1. The committee charged with the development of standards for coded representation of digital audio and video signal transmission. The standards as they are developed are accepted as ISO/IEC standards. These include: MPEG-1, the standard used for the coding of information on video CDs and in MP3 audio files; MPEG-2, the standard upon which digital television set top boxes and DVDs are based; MPEG-4, the standard for fixed and mobile web multimedia information transfer; and MPEG-7, the standard for the description and searching of audio and visual content of files, films, and audio tracks. The group has also developed MPEG-J, the framework for MPEG Java-based application programming interfaces, and is currently working on MPEG-21, a multimedia framework.
2. A family of video compression algorithms widely used in digital broadcasting and storage.
