9、Recommendations. Rec. ITU-T H.264.1 (02/2016) i Recommendation ITU-T H.264.1 Conformance specification for ITU-T H.264 advanced video coding Summary Recommendation ITU-T H.264.1 | International Standard ISO/IEC 14496-4 specifies tests designed to verify whether bitstreams and decoders meet the norma
10、tive requirements specified in Rec. ITU-T H.264 | ISO/IEC 14496-10: An encoder can claim conformance to Rec. ITU-T 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 Rec. ITU-T H.264 if it can pr
11、operly decode all bitstreams obeying constraints specified in Rec. ITU-T 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
12、in the context of the ITU-T/ISO/IEC 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, ISO/IEC 14496-4:2004/Amendment 30, ISO/IEC 14496-4:2004/Amendment 31, ISO/IEC 14496-4:2004/Amendment 3

The first approved version of Recommendation ITU-T H.264.1 (03/2005) included the specification of bitstreams for the testing of decoders for conformance
14、to the Baseline, Extended, Main, High, High 10, and High 4:2:2 profiles specified in Rec. ITU-T H.264 | ISO/IEC 14496-10. Corrigendum 1 to Recommendation H.264.1 (09/2005), which was integrated into the first published edition of Rec. ITU-T H.264.1, provided improved synchronization with the technic
15、ally-aligned twin text in ISO/IEC, removed some errors, and added tests for some required features that were not tested in the previous version. The second edition of Recommendation ITU-T H.264.1 (06/2008) provided corrections relative to the previous version of Rec. ITU-T H.264.1 and added addition
16、al bitstreams for the testing of 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 Rec. ITU-T H.264 | ISO/IEC 14496-10. The third edition of Recommendation ITU-T H.264.1 (04/2010) adds additional bits
17、treams for the testing of decoders for conformance to the Constrained Baseline, Scalable Baseline, Scalable High, Scalable High Intra, Multiview High, and Stereo High profiles specified in Rec. ITU-T H.264 | ISO/IEC 14496-10. Some of these added bitstreams are also specified for the testing of decod
18、ers for conformance to the previously-existing profiles. The fourth edition of Recommendation ITU-T H.264.1 (01/2012) corrects minor errors in the bitstreams and associated text specification. The fifth edition of Recommendation ITU-T H.264.1 (10/2014) adds additional bitstreams for the testing of d
19、ecoders for conformance to the Multiview Depth High and MFC (Multi-resolution Frame Compatible) High profiles specified in Rec. ITU-T H.264 | ISO/IEC 14496-10). The sixth edition of Recommendation ITU-T H.264.1 (02/2016) adds additional bitstreams for the testing of decoders for conformance to the E
20、nhanced Multiview Depth High and MFC (Multi-resolution Frame Compatible) Depth High profiles specified in Rec. ITU-T H.264 | ISO/IEC 14496-10).

ITU-T H.264.1 (02/2016) iii FOREWORD The International Telecommunication Union (ITU) is the United Nations specializ
24、ed agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with
25、a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recomm
26、endations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for con
27、ciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommen
28、dation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party
29、. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Righ
30、ts, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

ITU-T H.264.1 (02/2016) v Introduction This introduction does not form an integral part of this Recommendation | International Standard. This Recommendation
35、 | International Standard has been jointly developed by ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). It is published as technically-aligned twin text in both organizations (ITU-T and ISO/IEC). This Recommendation | International Standard specifies a se
36、t of tests designed to indicate whether bitstreams and decoders meet the normative requirements specified in ITU-T H.264 | ISO/IEC 14496-10. An encoder can claim conformance to ITU-T H.264 | ISO/IEC 14496-10 if the bitstreams that it generates are conforming bitstreams. Characteristics of coded bits
37、treams and decoders are specified for ITU-T H.264 | ISO/IEC 14496-10. The characteristics of a bitstream specify the subset of the standard that is exploited in the bitstream. Examples are the applied values or range of the picture size and bit rate parameters. Decoder characteristics specify the pr
38、operties and capabilities of the applied decoding process. The capabilities of a decoder specify which bitstreams the decoder can decode by specifying the subset of ITU-T H.264 | ISO/IEC 14496-10 that may be exploited in the bitstreams that it will decode. A bitstream can be decoded by a conforming
39、decoder if the characteristics of the bitstream are within the subset of the standard specified by the decoder capabilities. Procedures are specified for testing conformance of bitstreams and decoders to the requirements specified in ITU-T H.264 | ISO/IEC 14496-10. Given the set of characteristics c
40、laimed, the requirements that shall be met are fully determined by ITU-T H.264 | ISO/IEC 14496-10. This Recommendation | International Standard summarizes the requirements, cross references them to characteristics, and specifies how conformance with them can be tested. Guidelines are given on constr
41、ucting tests to verify bitstream and decoder conformance. This Recommendation | International Standard gives guidelines on how to construct bitstream test suites to check or verify decoder conformance. In addition, the test bitstreams implemented according to those guidelines are provided as an elec
42、tronic attachment to this Recommendation | International Standard. When the decoder under test does not satisfy the requirements of the tests, the decoder is not conforming to ITU-T H.264 | ISO/IEC 14496-10. These conformance tests make use of test data (bitstream test suites) provided as an electro
43、nic attachment to this Recommendation | International Standard, and the reference software decoder specified in ITU-T H.264.2 | ISO/IEC 14496-5 with source code available in electronic format. The bitstream files accompanying this Recommendation | International Standard, which require a substantial
44、amount of disk space, can be purchased in physical medium (DVD) from the ITU-T bookshop, or can be directly downloaded from the ITU-T Test Signal Database at http:/itu.int/net/ITU-T/sigdb/spevideo/Hseries-s.htm#H.264.1.
