scope:
This Recommendation defines the procedures for use of advanced video codecs, including ITU-T Rec. H.264, with H.300-series terminals, including H.310, H.320, H.321, H.322, H.323 and H.324. Such procedures include control, indication, capability exchange, and transport mechanisms.
Additionally, this Recommendation defines generic extended video control, indication, and capability signalling, applicable for use with all video codecs used in H.300-series multimedia terminals.
This revision adds clarifications regarding H.264 VCL HRD (Type I HRD) versus NAL HRD (Type II HRD) bit rate usage, sample aspect ratio capabilities for H.264, signalling for Reduced Complexity Decoding Operation (RCDO) for H.264 bitstreams, and a new Annex B, "RCDO for H.264 Baseline Profile bitstreams". Annex B specifies a reduced-complexity decoding process to be applied to H.264 Baseline profile bitstreams when such use has been negotiated using ITU-T Rec. H.241.
