Conformance specification for H.264 advanced video coding |
|
ITU-T Recommendation H.264.1 specifies tests designed to verify whether bitstreams and decoders meet the normative requirements specified in ITU-T Rec. H.264 | ISO/IEC 14496-10: • An encoder can claim conformance to ITU-T Rec. H.264 | ISO/IEC 14496-10 if the bitstreams that it generates are conforming bitstreams. • A decoder can claim conformance to a specified profile and level of ITU-T Rec. H.264 if it can properly decode all bitstreams obeying constraints specified in ITU-T Rec. H.264 | ISO/IEC 14496-10.The tests specified in this Recommendation provide methods for (non-exhaustive) testing of whether encoders and decoders meet these requirements. This twin text with ISO/IEC has been jointly developed in the context of the Joint Video Team (JVT) and has been submitted to ISO/IEC JTC 1/SC 29/WG 11 (MPEG) as ISO/IEC 14496-4:2002/Amendment 6 (2005 E), ISO/IEC 14496-4:2004/Amendment 9 and ISO/IEC 14496-4:2004/Amendment 30.Corrigendum 1 to H.264.1 (09/2005), which has been integrated into this edition of ITU-T Rec. H.264.1, provides improved synchronization with the technically-aligned twin text in ISO/IEC, removes some errors, and adds tests for some required features that were not tested in the previous version.This revised conformance specification provides corrections relative to the previous version of H.264.1 and adds additional bitstreams for the testing decoders for conformance to the High 4:4:4 Predictive, High 10 Intra, High 4:2:2 Intra, High 4:4:4 Intra, and CAVLC 4:4:4 Intra profiles specified in ITU-T Rec. H.264 | ISO/IEC 14496-10.The conformance bitstreams identified in H.264.1 are available as an electronic attachment to this Recommendation. |
