This Recommendation defines the procedures for use of advanced video codecs@ including those based on [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. 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 ITU-T H.300-series multimedia terminals. Annex A specifies ITU-T H.264 transport for ITU-T H.323 systems@ including Annex G of [ITU-T H.264] (Scalable Video Coding). Annex B specifies a reduced-complexity decoding process to be applied to ITU-T H.264 Baseline profile bitstreams when such use has been negotiated using [ITU-T H.241].
