Draft International Standard ISO/IEC 13818-2
Foreword
The ITU-T (the ITU Telecommunication Standardisation Sector) is a permanent organ of the
International Telecommunications Union (ITU). The ITU-T is responsible for studying technical,
operating and tariff questions and issuing Recommendations on them with a view to developing
telecommunication standards on a world-wide basis.
The World Telecommunication Standardisation Conference, which meets every four years,
establishes the program of work arising from the review of existing questions and new questions
among other things. The approval of new or revised Recommendations by members of the ITU-T is
covered by the procedure laid down in the ITU-T Resolution No. 1 (Helsinki 1993). The proposal
for Recommendation is accepted if 70% or more of the replies from members indicate approval.
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 specification is a committee draft that is being submitted for approval to the ITU-T,
ISO-IEC/JTC1 SC29. It was prepared jointly by SC29/WG11, also known as MPEG (Moving
Pictures Expert Group), and the Experts Group for ATM Video Coding in the ITU-T SG15. 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. The Experts
Group for ATM Video Coding was formed in 1990 to develop video coding standard(s) appropriate
for B-ISDN using ATM transport.
In this specification Annex A, Annex B and Annex C contain normative requirements and are an
integral part of this specification. Annex D, Annex E, Annex F and Annex G are informative and
contain no normative requirements.
ISO/IEC
This International Standard is published in four Parts.
13818-1 systems — specifies the system coding of the specification. It defines a multiplexed
structure for combining audio and video data and means of representing
the timing information needed to replay synchronised sequences in real-
time.
13818-2 video — specifies the coded representation of video data and the decoding process
required to reconstruct pictures.
13818-3 audio — specifies the coded representation of audio data.
13818-4 conformance— specifies the procedures for determining the characteristics of coded
bitstreams and for testing compliance with the requirements stated in
13818-1, 13818-2 and 13818-3.

Ziven_Zhou_Onslow2013-11-08为什么我下载下来才301K，文件大小和资源大小：1.1MB 不匹配，且下载后用word 2007打不开！
Arnold-FY-Chen2013-05-16明显是pdf转换过来的，还夹杂了很多word修订格式在里面，版面有点乱，还是94版本的
sjsj072013-08-20唯一的缺点就是有点乱，谢谢分享
