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.
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 not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO/IEC 14496-1:2004 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 specifies a system for the communication of interactive audio-visual scenes. The specification
includes the following elements:
1. the coded representation of natural or synthetic, two-dimensional (2D) or three-dimensional (3D) objects
that can be manifested audibly and/or visually (audio-visual objects) (specified in part 1, 2 and 3 of
ISO/IEC 14496);
2. the coded representation of the spatio-temporal positioning of audio-visual objects as well as their
behaviour in response to interaction (scene description, specified in parts 11 and 20 of ISO/IEC 14496);
3. the coded representation of information related to the management of data streams (synchronization,
identification, description and association of stream content, specified in parts 11 and 20 of
ISO/IEC 14496);
4. a generic interface to the data stream delivery layer functionality (specified in part 6 of ISO/IEC 14496);
5. an application engine for programmatic control of the player: format, delivery of downloadable Java byte
code as well as its execution lifecycle and behaviour through APIs (specified in part 11 of
ISO/IEC 14496); and
6. a file format to contain the media information of an ISO/IEC 14496 presentation in a flexible, extensible
format to facilitate interchange, management, editing, and presentation of the media.
The information representation, specified in ISO/IEC 14496-1, ISO/IEC 14496-11 and in ISO/IEC 14496-20,
describes the means to create a
