Packet ID for transport stream packets
containing video data; for TS only.
Packet ID for transport stream packets
containing audio data; for TS only.
There are 5 different tables followed by an array
of up to 188 bytes.The tables must be sent one
by one; the size of the tables is not defined but
limited to 188 bytes.

A discontinuity information table is inserted at
the beginning of the stream (after a stop of
recording).
At constant TS bit rate mode null packets are
delivered at the multiplexer output to achieve
the constant TS bit rate.
At variable TS bit rate mode no null packets are
inserted at the multiplexer output. This mode
can be used in combination with variable video
bit rate.
Packet ID for transport stream packets
containing PCR values; for TS only.
