This Recommendation 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 JVT and has been submitted to the ISO/IEC JTC 1/SC 29/WG 11 (MPEG) as ISO/IEC 14496-4:2002 / Amendment 6 (2005 E) and ISO/IEC 14496-4:2004 / Amendment 9.Corrigendum 1 to 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.For the pre-published version of H.264.1, the bitstreams associated to this Recommendation can be found at http://ftp3.itu.int/av-arch/jvt-site/draft_conformance |
