The MPEG systems coding specification

摘要

The MPEG Systems Committee has produced a specification for the syntax and semantics of system layer coding of combined MPEG compressed digital video and audio. The systems layer provides a framework and information required for these functions: a multiplex of various numbers of audio, video and private streams; synchronization of audio and video; management of buffers for coded information; random access and start-up conditions; and absolute time identification. In addition the specification allows for the later inclusion by ISO of other data streams.
