MPEG-4

Allikas: Vikipeedia

MPEG-4 on MPEG-standard (ISO/IEC-14496 [1]), mis kirjeldab muuhulgas video- ja audioandmete kadudega pakkimist. Tegemist on konteinerformaadiga (tähis MP4), mis koosneb 31 osast (standardid ISO/IEC 14496-1 kuni ISO/IEC 14496-31). Neis kirjeldatakse ka mitmesuguseid koodekeid, nagu nt audiokoodekid AAC ja HE-AAC ning videokoodekid DivX ja Xvid. Selle standardi järgi vormindatakse kõrgekvaliteedilisi audio- ja videofaile.

Konteineris on standarditud ka intellektuaalomandi kaitse süsteem DRM ( Digital Right Management).
