Information technology — Coding of audio-visual objects — Part 1: Systems
ISO/IEC 14496-1:2004 specifies system-level functionalities for the communication of interactive audio-visual scenes. It specifies the following tools: a terminal model for time and buffer management; a coded representation of metadata for the identification, description and logical dependencies of the elementary streams; a coded representation object content information, a descriptive audio-visual content information; an interface to intellectual property management and protection systems; a coded representation of synchronization information; and a multiplexed representation of individual elementary streams in a single stream.

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.
The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC)
draw attention to the fact that it is claimed that compliance with this document may involve the use of a patent.
The ISO and IEC take no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the ISO and IEC that he is willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect,
the statement of the holder of this patent right is registered with the ISO and IEC. Information may be obtained
from the companies listed in Annex J.
ISO/IEC 14496-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
This third edition cancels and replaces the second edition (ISO/IEC 14496-1:2001). It also
incorporates the Amendments ISO/IEC 14496-1:2001/Amd.1:2001, ISO/IEC 14496-1:2001/Amd.3:2004,
ISO/IEC 14496-1:2001/Amd.4:2003 and ISO/IEC 14496-1:2001/Amd.7:2004, which have been technically
revised.
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
