'''MPEG-2''' (a.k.a. H.222/H.262 as was defined by the [[ITU]]) is a standard for "the generic [[video coding format|coding of moving pictures]] and associated audio information".<ref>{{cite web|url=http://www.iso.org/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=31537|title=ISO/IEC 13818-1:2000 - Information technology -- Generic coding of moving pictures and associated audio information: Systems|website=www.iso.org|access-date=4 May 2018|url-status=live|archive-url=https://web.archive.org/web/20070520030715/http://www.iso.org/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=31537|archive-date=20 May 2007}}</ref> It describes a combination of [[Lossy compression|lossy]] [[video compression]] and [[Lossy compression|lossy]] [[audio data compression]] methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as [[H.264/AVC]] and [[HEVC|H.265/HEVC]], backwards compatibility with existing hardware and software means it is still widely used, for example in over-the-air [[digital television]] broadcasting and in the [[DVD-Video]] standard.
