MPEG-3
Sign in to saveMPEG-3 was the designation for an abandoned plan to create a group of audio and video coding standards agreed upon by the Moving Picture Experts Group (MPEG) designed to handle HDTV signals at 1080p in the range of 20 to 40 megabits per second. MPEG-3 was launched as an effort to address the need of an HDTV standard while work on MPEG-2 was underway, but it was soon discovered that MPEG-2, at high data rates, would accommodate HDTV. Thus, in 1992 HDTV was included as a separate profile in the MPEG-2 standard and MPEG-3 was rolled into MPEG-2.

MPEG-3 è il nome in codice dato dal gruppo MPEG (Motion Pictures Coding Experts Group) a uno standard di compressione video nato per gestire lo standard HDTV manipolando il flusso audio e video. Lo standard era progettato per gestire flussi di dati in un intervallo compreso tra i 20 e i 40 Mbps. Successivamente si è scoperto che simili risultati potevano essere ottenuti apportando delle modifiche marginali allo standard MPEG-2 e quindi si è deciso di dismettere lo standard MPEG-3. MPEG-3 non va confuso con l'MPEG-1 Layer 3 comunemente conosciuto come MP3.
