19、reword IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technica
20、l committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part i
21、n the work. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3. In the field of information technology, IS0 and IEC have established a joint technical committee, ISOAEC JTC 1. Draft International Standards adopted by the joint technical committee
22、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 part of ISOAEC 14495 may be the subject of patent rights other than
23、 those identified in annex J. IS0 and IEC shall not be held responsible for identifying any and all such patent rights. International Standard ISOAEC 14495-1 was prepared by Joint Technical Committee ISOAEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and h
