Moving Picture Experts Group (MPEG) a working group of ISO/IEC in charge of the development of standards for coded representation of digital audio and video. Established in 1988, the group has produced MPEG-1, the standard on which such products as Video CD and MP3 are based, MPEG-2, the standard on which such products as Digital Television set top boxes and DVD are based, MPEG-4, the standard for multimedia for the fixed and mobile web, MPEG-7, the standard for description and search of audio and visual content and MPEG-21, the Multimedia Framework.


MPEG standards can be purchased directly from ISO by email, from their website or from a National Body. Some MPEG standards are publicly available (including reference software of all MPEG standards).

the reference software can download from:

中文简单解释:

【什么是MPEG1,2,4以及他们和ISO/IEC 11172 ,13813,14496的关系】

MPEG是一个组织,是ISO旗下的,专门分管开发音视频标准的组织。

而我们通常所说的MPEG-1,MPEG-2,MPEG-4等,指的是其对应的音视频标准的总称。

ISO/IEC 组织制定的N多的标准,一般以数字表示。而其中的ISO/IEC 11172,ISO/IEC 13813,ISO/IEC 14496就分别对应MPEG-1,MPEG-2,MPEG-4。

而MPEG-1,MPEG-2,MPEG-4是其制定的那些对应的标准的大家所常说的普通名称,。

其中每个标准具体还有子部分,包括系统,音频,视频,兼容性等等。

多说一句:其中有些标准后的AMD stands for Amendment, and is issued whenever new functionality is added to the standard, such as the streaming video profiles

每个标准包含哪些部分的具体解释如下:

MPEG-1 (即ISO/IEC 11172)


MPEG-1 is a standard in 5 parts:

This standard is published in four parts.

Part 1 – systems – specifies the system coding layer of the standard. It defines a multiplexed structure for combining audio and video data and means of representing the timing information needed to replay synchronized sequences in real-time.

Part 2 – video – specifies the
coded representation of video data and the decoding process required to reconstruct pictures. Part 3 – audio – specifies the coded representation of audio data.

Part 4 – conformance testing – is still in preparation.(注:这个是当时1991年的版本,其实现在早就制定好了,最新的已经有MPEG-7和MPEG-21了) It will specify the procedures for determining the characteristics of coded bit streams and for testing compliance with the requirements stated in Parts 1, 2 and 3.

MPEG-2(即ISO/IEC 13813)


MPEG-2 is a standard currently in 9 parts. The first three parts of of MPEG-2 have reached International Standard status, other parts are at different levels of completion. One has been withdrawn

  • ISO/IEC 13818-1:2000 Information technology — Generic coding of moving pictures and associated audio information: Systems (available in English only)

  • ISO/IEC 13818-6:1998/Amd 2:2000 Additions to support synchronized download services, opportunistic data services and resource announcement in broadcast and interactive services (available in English only)
  • ISO/IEC 13818-7:1997 Information technology — Generic coding of moving pictures and associated audio information — Part 7: Advanced Audio Coding (AAC) (available in English only)
  • ISO/IEC 13818-7:1997/Cor 1:1998 (available in English only)
  • ISO/IEC 13818-9:1996 Information technology — Generic coding of moving pictures and associated audio information — Part 9: Extension for real time interface for systems decoders (available in English only)
  • ISO/IEC 13818-10:1999 Information technology — Generic coding of moving pictures and associated audio information — Part 10: Conformance extensions for Digital Storage Media Command and Control (DSM-CC) (available in English only)

ISO/IEC 13818 consists of the following parts, under the general title Information technology — Generic coding of moving pictures and associated audio information:
Part 1: Systems
Part 2: Video
Part 3: Audio
Part 4: Conformance testing
Part 5: Software simulation
Part 6: Extensions for DSM-CC
Part 7: Advanced Audio Coding (ACC)
Part 9: Extension for real time interface for systems decoders
Part 10: Conformance extensions for Digital Storage Media Command and Control (DSM-CC)

注:这个是第二个版本的,2000年的,第一个版本的是1996年的。


MPEG-4(即ISO/IEC 14496)

What are the different parts of the MPEG-4 Standard?

Currently MPEG-4 is broken down into 8 Separate parts, some of which are still under development and are not available for purchase from ISO.

  • ISO/IEC 14496-1 (Systems)
    Contains tools such as BiFS, Object Descriptors, FlexMux, MP4 File Format, etc.
  • ISO/IEC 14496-2 (Visual)
    Includes natural and synthetic coding as well as Facial and Body Animation.
  • ISO/IEC 14496-3 (Audio)
    Including Speech coding, General Audio Coding, Structured Audio, Text to Speech interface, Parameteric Audio.
  • ISO/IEC 14496-4 (Conformance)
    Specifies tests to be performed to verify whether bitstreams and decoders meet the requirements of parts 1, 2, 3, and 6.
  • ISO/IEC 14496-5 (Reference Software)
    Unoptimized software implementation of the MPEG-4 specification.
  • ISO/IEC 14496-6 (Delivery Multimedia Integration Framework
    Provides a means for transparent access and delivery of content irrespective of delivery technologies.
  • ISO/IEC 14496-7 (Optimised software for MPEG-4 tools) — Under development
  • ISO/IEC 14496-8 (4 on IP framework) — Under developement
    A framework for transmitting MPEG-4 over IP neworks
