Hello everyone, I have the following question regarding RFC 4629. I would
really appreciate your feedback. Thank you in advance, Regis J. Crinon Fact 1: H.263+ includes a set of new Annexes: Annex I through T. Fact 2: RFC 4629 account for ONLY a subset of these annexes. See
excerpts from the RFC below: A list of optional
annexes specifies which annexes of H.263 are
supported. The optional annexes are defined as part of H263-1998,
H263-2000. H.263 annex X [H263] defines profiles that group
annexes for specific applications. A system that supports a
specific annex SHALL specify its support using the optional
parameters. If no annex is specified, then the stream is Baseline
H.263.
The allowed optional parameters for the annexes are "F",
"I", "J",
"T", "K", "N", and "P". Question How are the other annexes signaled? Example: How can I
signal that an H.263+ bistream uses Annex L or Annex M or Annex O or Annex Q or
Annex R or Annex S? It seems that I cannot use SDP to tell a video bitstream
that uses one or more of these annexes from one that does not. Hence the
question. |
