Widely adopted for filemaking, DVD disks, and other applications. See list of ISO documents in Format specifications below. Part 2 concerns the coding and specifies profiles and levels.
Ten parts have been published parts 1, 2, 3, and 7 are central. Developed in joint partnership with ITU-T, who published the "common text" as H. Developed by ISO technical program called the Moving Picture Experts Group (MPEG), Coding of audio, picture, multimedia and hypermedia information. Matroska File Format with MPEG-2 Video Encoding (H.262) MPEG-1 and MPEG-2 Layer II Audio Encoding MPEG-2 File with 422 Video and Layer II Audio Encoding MPEG-2 File with Main Profile Video and Layer II Audio Encoding Not described at this Web site at this time. MPEG-2 program stream or file with MPEG-2 video and AES3 Digital Audio Interface, SMPTE Extensions (Dolby and surround audio encoding). Other MPEG-2 profiles not documented at this time: SNR Scalable, Spatially Scalable, and High. Generally a final-state (end-user delivery) format MPEG-2_MP, Main Profile, or MPEG-2_422, 4:2:2 Profile, may be used as middle-state (broadcast production) formats. Picture and sound elementary streams are combined to produce single-program program streams, which may be further combined with other programs in a multi-program transport stream. An elementary stream is broken up into packets of variable length, forming a packetized elementary stream (PES). All MPEG-2 streams (picture, sound or data) are based on elementary streams in the case of picture (video), the elementary stream contains compressed frame images, plus sequence headers, group-of-picture (GOP) headers, and other data needed to decode the stream. The key techniques employed in the MPEG-2 codec include intra-frame Discrete Cosine Transform (DCT) coding and motion-compensated inter-frame prediction See Notes for more detail.
This description pertains to the video or picture encoding defined by the MPEG-2 family of specifications.
