Extended video procedures and control signals for ITU-T H.300-series terminals |
|
Recommendation ITU-T H.241 defines the use of advanced video codecs, including those based on Recommendation ITU-T H.264, in ITU-T H.300-series terminals, including ITU-T H.310, ITU T H.320, ITU-T H.321, ITU-T H.322, ITU-T H.323 and ITU-T H.324 terminals. It also defines generic extended signalling for use with all video codecs in the ITU-T H.300 series terminals.
This revised version introduces a number of enhancements and clarifications to the previous version. Clarification concerns primarily the description on the signalling for ITU-T H.264 Annex G Scalable Baseline and Scalable High Profiles, a procedure for selecting the operating point of a scalable video coding (SVC) video stream, and the Capability Class of ITU-T H.241 capabilities. This version incorporates clause 6.2.5 introduced in ITU-T H.241 (2006) Amd. 1 (2008), allowing for the negotiation of particular video submodes of ITU-T H.264 encoding. It also incorporates clause 8.3.2.14, defining a new optional ITU-T H.264 capability parameter (MaxFPS), and Appendix II which contains non-normative examples describing the use of clause 6.2.5. Clause 8.3.2.14 and Appendix II were both introduced in ITU-T H.241 (2006) Amd. 2 (2009).
