标准简介：This Recommendation | International Standard specifies the system layer of the coding. It was developed principally to
support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system
layer supports six basic functions:
1) the synchronization of multiple compressed streams on decoding;
2) the interleaving of multiple compressed streams into a single stream;
3) the initialization of buffering for decoding start up;
4) continuous buffer management;
5) time identification;
6) multiplexing and signalling of various components in a system stream.
An ITU-T Rec. H.222.0 | ISO/IEC 13818-1 multiplexed bit stream is either a Transport Stream or a Program
Stream. Both streams are constructed from PES packets and packets containing other necessary information. Both
stream types support multiplexing of video and audio compressed streams from one program with a common time base.
The Transport Stream additionally supports the multiplexing of video and audio compressed streams from multiple
programs with independent time bases. For almost error-free environments the Program Stream is generally more
appropriate, supporting software processing of program information. The Transport Stream is more suitable for use in
environments where errors are likely.
An ITU-T Rec. H.222.0 | ISO/IEC 13818-1 multiplexed bit stream, whether a Transport Stream or a Program Stream, is
constructed in two layers: the outermost layer is the system layer, and the innermost is the compression layer. The
system layer provides the functions necessary for using one or more compressed data streams in a system. The video
and audio parts of this Specification define the compression coding layer for audio and video data. Coding of other
types of data is not defined by this Specification, but is supported by the system layer provided that the other types of
data adhere to the constraints defined in 2.7.
