10、 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 with particular fields of technical activity. ISO and IEC technical committees coll

In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standard

12、s 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 joint technical committee are circulated to national bodies for voting. Publication a

Amendment 10 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. This amendment specifies conformance tests for Levels 4a and 5 of the ISO/IEC 14496-2 Si

15、mple Profile. The bitstreams to be used for conformance testing of these levels accompany this document.
