Questions tagged [mpeg-2]

Questions related to MPEG-2, an ISO/IEC standard for video/audio compression and systems. MPEG-2 standard was successor to MPEG-1 standards. MPEG-2 is at the core of most digital television and DVD formats.

MPEG-2 is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods which permit storage and transmission of movies using currently available storage media and transmission bandwidth.

MPEG-2 is widely used as the format of digital television signals that are broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV systems. It also specifies the format of movies and other programs that are distributed on DVD and similar discs.

MPEG-2 systems specification, encompasses MPEG transport stream (used in ATSC/DVB/ISDB/SBTVD broadcasting, and HDV recording on tape) and MPEG program stream (used as container format in file-based media such as hard disk drives, optical discs and flash memory)
