SS 461-1:1999
Information technology – Coding of moving pictures and associated audio for digital storage media at up to about 1.5 Mbit/s - Systems (Refer to ISO/IEC 11172-1:1993)
OVERVIEW
Specifies the system layer of the coding and is developed to support the combination of video and audio coding methods defined in Parts 2 and 3. The system layer supports five basic functions:
- The synchronisation of multiple compressed streams on playback
- The interleaving of multiple compressed streams into a single stream
- The initialisation of buffering for playback start up
- Continuous buffer management, and
- Time identification
The multiplexed bit stream is constructed in 2 layers: the outermost 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 the specifications, but is supported by the system layer provided that the other types of data adhere to the constraints defined in clause 2.4.
