INTERNATIONAL ORGANISATION FOR STANDARDISATION

CODING OF MOVING PICTURES AND AUDIO

The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of
telecommunications. The ITU Telecommunication Standardisation Sector (ITU-T) is a permanent organ of ITU. ITU-T
is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to
standardising telecommunications on a world-wide basis. The World Telecommunication Standardisation Assembly
(WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups that, in turn, produce
Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in
WTSA Resolution 1. In some areas of information technology that fall within ITU-T's purview, the necessary standards
are prepared on a collaborative basis with ISO and IEC.
ISO (the International Organisation for Standardisation) and IEC (the International Electrotechnical Commission) form
the specialised system for world-wide standardisation. National Bodies that are members of ISO and IEC participate in
the development of International Standards through technical committees established by the respective organisation to
deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest.
Other international organisations, 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 JTC1.
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.
This Recommendation | International Standard was prepared jointly by ITU-T SG16 Q.6, also known as VCEG (Video
Coding Experts Group), and by ISO/IEC JTC1/SC29/WG11, also known as MPEG (Moving Picture Experts Group).
VCEG was formed in 1997 to maintain prior ITU-T video coding standards and develop new video coding standard(s)
appropriate for a wide range of conversational and non-conversational services. MPEG was formed in 1988 to establish
standards for coding of moving pictures and associated audio for various applications such as digital storage media,
distribution and communication.
In this Recommendation | International Standard Annexes A through E contain normative requirements and are an
integral part of this Recommendation | International Standard.
