11、ional 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 with particular field
12、s 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 have established a jo
13、int 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 joint technical committ
14、ee 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. ISO and IEC shall
15、not be held responsible for identifying any or all such patent rights. Amendment 5 to ISO/IEC 14496-2:2004 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 tw
16、o new Levels for the ISO/IEC 14496-2 Simple Studio Profile: Levels 5 and 6. These levels define increased capabilities of VMV size, VCV buffer size, VCV decoder rate, VBV buffer size, and bit rate for the Simple Studio Profile. In particular, Level 5 provides support for typical visual session sizes
17、 of 4Kx2K24p/30p in rectangular-VOP luminance sample units. Level 6 provides support for typical visual session sizes of 4Kx2K60p in rectangular-VOP luminance sample units.
