12、hrough 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-governmental, in liaison with ISO and IEC, a
13、lso 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 joint technical committee is to p

16、e SC 29, Coding of audio, picture, multimedia and hypermedia information. This Amendment establishes conformance test requirements for conformance to ITU-T Rec. H.264 ISO/IEC 14496-10. In this Amendment, additional text to ITU-T Rec. H.264ISO/IEC 14496-10 is specified for testing the conformance of
17、ITU-T Rec. H.264 | ISO/IEC 14496-10 video decoders including in particular the SVC Profiles, which consist of the Scalable Baseline, Scalable High, and Scalable High Intra profiles. The following subclauses specify the normative tests for verifying conformance of ITU-T Rec. H.264 ISO/IEC 14496-10 vi
18、deo bitstreams and decoders. These normative tests make use of test data (bitstream test suites) provided as an electronic annex to this document, and of the reference software decoder specified in ISO/IEC 14496-5 with source code available in electronic format. The numbering in this Amendment is re
19、lative to the text of ISO/IEC 14496-4. When a numbered item (i.e., a clause, subclause, 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 o
20、f the corresponding numbered item immediately preceding it is used and the letter 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 ord
21、inary English alphabetical order. If text integrating this Amendment with ISO/IEC 14496-4 is produced, the inserted numbered items with appended letters are to be assigned to corresponding numbers in their numerical order without any such letters, and any subsequent numbered items are to be assigned
22、 later numbers to avoid conflicts. The purpose of the numbering convention in this Amendment text is to avoid the renumbering of existing numbered items in ISO/IEC 14496-4 while drafting this Amendment. Therefore, if the addition of a numbered item does not require renumbering of numbered items in I
23、SO/IEC 14496-4, the final number is assigned to the numbered item herein.

28、6.5.5 and the dynamic test defined in subclause 10.6.5.6 with all the bitstreams of the normative test suite specified for testing decoders of this particular profile-and-level. Tables 1 and 2 define the normative test suites for each profile-and-level combination. The test suite for a particular pr
29、ofile-and-level combination is the list of bitstreams that are marked with an “X” in the column corresponding to that profile-and-level combination. “X” indicates that the bitstream is designed to test both the dynamic and static conformance of the decoder. The bitstream column specifies the bitstre
