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:
| Standard | ISO/IEC No. | Reference software |
| MPEG-1 | ISO/IEC 11172-5:1998 | Software |

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 is a standard in 5 parts:
- ISO/IEC 11172-1:1993 Information technology — Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s — Part 1: Systems
- ISO/IEC 11172-1:1993/Cor 1:1996 (available in English only)
- ISO/IEC 11172-1:1993/Cor 2:1999 (available in English only)
- ISO/IEC 11172-2:1993 Information technology — Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s — Part 2: Video
- ISO/IEC 11172-2:1993/Cor 1:1996 (available in English only)
- ISO/IEC 11172-2:1993/Cor 2:1999 (available in English only)
- ISO/IEC 11172-3:1993 Information technology — Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s — Part 3: Audio
- ISO/IEC 11172-3:1993/Cor 1:1996 (available in English only)
- ISO/IEC 11172-4:1995 Information technology — Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s — Part 4: Compliance testing (available in English only)
- ISO/IEC TR 11172-5:1998 Information technology — Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s — Part 5: Software simulation (available in English only)
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 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
