National bodies that are members of ISOorIECparticipateinthedevelopmentofInternationalStandardsthroughtechnicalcommitteesestablished 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, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint 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 avote. International Standard ISO/IEC 13818-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. This second edition cancels and replaces the first edition (ISO/IEC 13818-3:1995), which has been technically revised. ISO/IEC 13818 consists of the following parts, under the general title Information technology - Generic coding of moving pictures and associated audio information: -Part 1: Systems -Part2:Video - Part 3: Audio - Part 4: Compliance testing -Part 5: Software simulation - Part 6: Extensions for DSM-CC - Part 7: Advanced Audio Coding (AAC) -Part 9: Extension for real time interface for systems decoders - Part 10: Conformance extensions for DSM-CC Annexes A and B form an integral part of this part of ISO/IEC 13818.
