8、d IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal wi
9、th 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, also take part in the work. In the field of information technology, ISO and IEC ha
10、ve 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 prepare International Standards. Draft International Standards adopted by the join
11、t 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

Amendment 28 to ISO/IEC 14496-4:2004 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. It spec
13、ifies conformance tests for Level 6 of the ISO/IEC 14496-2 Simple Profile. The bitstreams to be used for conformance testing of this level accompany this document. -,-,- -,-,- ISO/IEC 14496-4:2004/Amd.28:2008(E) ISO/IEC 2008 All rights reserved 1 Information technology Coding of audio-visual objects

15、 coded at frame rate 30 frames per second without data partitioning and with bit rate 12000 Kbps. The number of MB/s, packet size and bit rate are the maximum allowed for the profile-and-level combination. To achieve the maximum bit rate, several MBs are INTRA coded for each frame. The VBV approache
16、s the maximum, then approaches the minimum after removal of a frame that is nearly as large as the vbv_buffer_size. Functional stage: VBV Purpose: Check that the decoder has sufficient buffering and I/O bandwidth for Simple Profile Level 6. In 5.5.8, add the following table after Table 11: Table AMD
