System Layer
The system layer is the transport stream with program data and associated metadata
that describes the composition and organization of the transport stream. MPEG-2
system layer information includes synchronization bytes, PID numbers, scrambling
information, and other indicators, including the start of the transport packet payload.
Transport packets can be PES packet, a PSI table, or other private data. ATSC and
DVB transport streams are MPEG-2 compatible because the required ATSC and
DVB system layer data are MPEG-2 private data structures.
See the appropriate MPEG-2, DVB, or ATSC standards for more information.
