Moving Picture Experts Group         
<compression, standard, algorithm, file format, body> (MPEG, ISO/IEC JTC1/SC29 WG11) An ISO committee that generates standards for digital video compression and audio. Also the name of their algorithms. MPEG-1 is optimised for CD-ROM and is the basis for MP3. MPEG-2 is aimed at broadcast quality video for applications such as digital television set-top boxes and DVD. MPEG-4 is a standard for low bandwidth {video telephony} and multimedia on the World-Wide Web. MPEG-3 was merged into MPEG-2. mpeg/">http://cselt.it/mpeg/. {MPEG.org (http://mpeg.org/)}. {mpeg/">MPEG decoder (ftp://toe.cs.berkeley.edu/pub/multimedia/mpeg/)}. {mpeg/">MPEG routines (ftp://ftp.mni.mcgill.ca/pub/mpeg/)}.

Moving Picture Experts Group         
The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications.John Watkinson, The MPEG Handbook, p.

<compression, standard, algorithm, file format> The first MPEG format for compressed video, optimised for CD-ROM. MPEG-1 was designed for the transmission rates of about 1.5 Mbps achievable with Video-CD and CD-i. It uses discrete cosine transform (DCT) and Huffman coding to remove spatially redundant data within a frame and block-based motion compensated prediction (MCP) to remove data which is temporally redundant between frames. Audio is compressed using subband encoding. These algorithms allow better than VHS quality video and almost CD quality audio to be compressed onto and streamed off a single speed (1x) CD-ROM drive. MPEG encoding can introduce blockiness, colour bleed and shimmering effects on video and lack of detail and quantisation effects on audio. The official name of MPEG-1 is International Standard IS-11172. (1999-01-06)

Moving Picture Experts Group

The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications. Together with JPEG, MPEG is organized under ISO/IEC JTC 1/SC 29 – Coding of audio, picture, multimedia and hypermedia information (ISO/IEC Joint Technical Committee 1, Subcommittee 29).

MPEG formats are used in various multimedia systems. The most well known older MPEG media formats typically use MPEG-1, MPEG-2, and MPEG-4 AVC media coding and MPEG-2 systems transport streams and program streams. Newer systems typically use the MPEG base media file format and dynamic streaming (a.k.a. MPEG-DASH).
