The '''Moving Picture Experts Group''' ('''MPEG''') is an alliance of [[working group]]s established jointly by [[International Organization for Standardization|ISO]] and [[International Electrotechnical Commission|IEC]] that sets standards for media coding, including compression coding of [[audio compression (data)|audio]], [[video compression|video]], graphics, and [[Compression of Genomic Sequencing Data|genomic]] data; and transmission and [[Container format (digital)|file formats]] for various applications.<ref name="TMH-2">John Watkinson, ''The MPEG Handbook'', p. 1</ref> Together with [[Joint Photographic Experts Group|JPEG]], MPEG is organized under [[ISO/IEC JTC 1]]/[[ISO/IEC JTC 1/SC 29|SC 29]] – ''Coding of audio, picture, multimedia and hypermedia information'' (ISO/IEC Joint Technical Committee 1, Subcommittee 29).<ref name=SC29atJTC1/><ref name=FutureSC29/><ref name="wg11-structure">{{cite web|author=ISO, IEC|date=2009-11-05|title=ISO/IEC JTC 1/SC 29, SC 29/WG 11 Structure (ISO/IEC JTC 1/SC 29/WG 11 – Coding of Moving Pictures and Audio)|url=http://kikaku.itscj.ipsj.or.jp/sc29/29w12911.htm|url-status=dead|archive-url=https://web.archive.org/web/20010128180300/http://www.itscj.ipsj.or.jp/sc29/29w12911.htm|archive-date=2001-01-28|access-date=2009-11-07}}</ref><ref>{{cite web|author=MPEG Committee|title=MPEG – Moving Picture Experts Group|url=http://wg11.sc29.org/index.xalter|url-status=dead|archive-url=https://web.archive.org/web/20080110041626/http://wg11.sc29.org/index.xalter|archive-date=2008-01-10|access-date=2009-11-07}}</ref><ref>{{cite web|author=ISO|title=MPEG Standards – Coded representation of video and audio|url=http://www.iso.org/iso/prods-services/popstds/mpeg.html|url-status=dead|archive-url=https://web.archive.org/web/20110514060335/http://www.iso.org/iso/prods-services/popstds/mpeg.html|archive-date=2011-05-14|access-date=2009-11-07}}</ref><ref>{{cite web|author=ISO|title=JTC 1/SC 29 – Coding of audio, picture, multimedia and hypermedia information|url=http://www.iso.org/iso/standards_development/technical_committees/list_of_iso_technical_committees/iso_technical_committee.htm?commid=45316|access-date=2009-11-11}}</ref>

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 [[MPEG transport stream|transport streams]] and [[MPEG program stream|program streams]]. Newer systems typically use the MPEG [[ISO/IEC base media file format|base media file format]] and [[Dynamic Adaptive Streaming over HTTP|dynamic streaming]] (a.k.a. [[MPEG-DASH]]).
