Transport of MPEG-1 in TS was defined in the original version of
13818-1.
Support for carrying MPEG-4 streams in TS was added in an ammedment (#7,
I think). Streams can
be either Sync Layer-packetised elementary streams or FlexMux streams.
Both can be encapsulated as
PES or as private sections. In the 2000 edition of 13818-1, section 2.11
describes this in detail.
Proposed mappings for VC9 into TS (now called VC1, to avoid confusion)
have been published by ATSC
as part of their ATSC-E proposals. That can be found on their website. I
have seen references to, but
have not seen, a similar document from SMPTE to accompany the formal VC1
spec when it is released.
