Foreword
ISO (the International Organization for Standardization) and 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 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.
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 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.
ISO/IEC 14496-14 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
ISO/IEC 14496 consists of the following parts, under the general title Information technology — Coding of
audio-visual objects:
Part 1: Systems
Part 2: Visual
Part 3: Audio
Part 4: Conformance testing
Part 5: Reference software
Part 6: Delivery Multimedia Integration Framework (DMIF)
Part 7: Optimized reference software for coding of audio-visual objects
Part 8: Carriage of ISO/IEC 14496 contents over IP networks
Part 9: Reference hardware description
Part 10: Advanced Video Coding (AVC)
Part 11: Scene description and application engine
Part 12: ISO base media file format
Part 13: Intellectual Property Management and Protection (IPMP) extensions
Part 14: MP4 file format
Part 15: Advanced Video Coding (AVC) file format
Part 16: Animation Framework eXtension (AFX)
