28、9:2006(E) ISO/IEC 2006 All rights reserved iiiForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the develop
29、ment of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmenta
30、l, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the
31、joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Att
32、ention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 6 to ISO/IEC 14496-4:2004 was prepared by Joint Technical Committee ISO/IEC JTC 1, Inf
33、ormation technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. ISO/IEC 14496-4:2004/Amd.9:2006(E) iv ISO/IEC 2006 All rights reservedIntroduction This Recommendation | International Standard establishes conformance test requirements for conformance to ITU-T
34、 Rec. H.264 | ISO/IEC 14496-10. In this document, the additional text to ITU-T Rec. H.264.1 | ISO/IEC 14496-4 is specified for the conformance test of ITU-T Rec. H.264 | ISO/IEC 14496-10 video decoders. This specification is specifically applied to ITU-T Rec. H.264 | ISO/IEC 14496-10, AVC Fidelity R
35、ange Extensions. The following subclauses specify the normative tests for verifying conformance of ITU-T Rec. H.264 | 14496-10 video bitstreams and video decoders. Those normative tests make use of test data (bitstream test suites) provided as an electronic annex to this document, and of the referen
36、ce software decoder specified in ITU-T Rec. H.264.2 | ISO/IEC 14496-5 with source code available in electronic format. The numbering in this fidelity range extensions conformance amendment text is relative to the text of ITU-T Rec. H.264.1 | ISO/IEC 14496-4. When a numbered item (i.e., a clause, sub
37、clause, figure, table, or equation) or associated content is being replaced or modified, the same number is used for the modified numbered item. When a numbered item is inserted between prior numbered items, the number of the corresponding numbered item immediately preceding it is used and the lette
38、r a is appended to this number. When, after this one such inserted numbered item, another numbered item is inserted, the letter a is replaced by the letter b to indicate their relative order, and so on, following ordinary English alphabetical order. If text integrating this amendment with ITU-T Rec.
39、 H.264.1 | ISO/IEC 14496-4 is produced, the inserted numbered items are to be assigned the corresponding number in their numerical order without any such letters, and any subsequent numbered items are to be assigned later numbers to avoid conflicts. The purpose of the numbering convention in this am
40、endment text is to avoid renumbering of numbered items in ITU-T Rec. H.264 | ISO/IEC 14496-4 while drafting this amendment. Therefore, if the addition of a numbered item does not require renumbering of numbered items in ITU-T Rec. H.264 | ISO/IEC 14496-4, the final number is assigned to the numbered
41、 item herein.

42、ance bitstreams are included in this specification as an electronic attachment. The following information is included in a single zipped file for each such bitstream. ITU-T Rec. H.264 | ISO/IEC 14496-10 video bitstream; Reconstructed pictures or hashes of decoded pictures (may not be present); Short
43、 description of the bitstream; Trace file (the bitstream in ASCII format). In cases where the reconstructed pictures or hashes of decoded pictures are not available, the reference software of ITU-T Rec. H.264.2 | ISO/IEC 14496-5 shall be used to generate the necessary reference reconstructed picture
44、s from the bitstream. Replace subclause 10.6.5.5 with: 10.6.5.5 Static tests for output order conformance Static tests of a video decoder require testing of the reconstructed samples. This subclause will explain how this test can be accomplished when the reconstructed samples at the output of the de
45、coding process are available. It may not be possible to perform this type of test with a production decoder (due to the lack of an appropriate accessible interface in the design at which to perform the test). In that case this test should be performed by the manufacturer during the design and develo
46、pment phase. Static tests are used for testing the decoding process. The test will check that the values of the samples reconstructed by the decoder under test shall be identical to the values of the samples reconstructed by the reference decoder. When a hash of the values of the samples of the deco
47、ded pictures is attached to the bitstream file, a corresponding hash operation performed on the values of the samples of the decoded pictures produced by the decoder under test shall produce the same results. Replace subclause 10.6.5.7 with: 10.6.5.7 Decoder conformance test of a particular profile-
48、and-level In order for a decoder of a particular profile-and-level to claim output order conformance to the standard as described by this Specification, the decoder shall successfully pass the static test defined in subclause 10.6.5.5 with all the bitstreams of the normative test suite specified for
49、 testing decoders of this particular profile-and-level. ISO/IEC 14496-4:2004/Amd.9:2006(E) 2 ISO/IEC 2006 All rights reservedIn order for a decoder of a particular profile and level to claim output timing conformance to the standard as described by this Specification, the decoder shall successfully pass both the static test defined in subclause 10.6.5.5 and the dynamic test defined in subclause 10.6
