MPEG Format is used on several media. This picture relates some of the most known media to the MPEG Format version and container format (TS and PS) used.

The Moving Picture Experts Group (MPEG) is a working group of experts that was formed by ISO and IEC to set standards for audio and video compression and transmission.[1] It was established in 1988 by the initiative of Hiroshi Yasuda (Nippon Telegraph and Telephone) and Leonardo Chiariglione,[2] group Chair since its inception. The first MPEG meeting was in May 1988 in Ottawa, Canada.[3][4][5] As of late 2005, MPEG has grown to include approximately 350 members per meeting from various industries, universities, and research institutions. MPEG's official designation is ISO/IEC JTC1/SC29 WG11 – Coding of moving pictures and audio (ISO/IEC Joint Technical Committee 1, Subcommittee 29, Working Group 11).[6][7][8][9]

Sub Groups[edit]

ISO/IEC JTC1/SC29/WG11 – Coding of moving pictures and audio has following Sub Groups (SG):[6]

Cooperation with other groups[edit]

Joint Video Team[edit]

Joint Video Team (JVT) is joint project between ITU-T SG16/Q.6 (Study Group 16 / Question 6) – VCEG (Video Coding Experts Group) and ISO/IEC JTC1/SC29/WG11 – MPEG for the development of new video coding recommendation and international standard.[6][10] It was formed in 2001 and its main result has been H.264/MPEG-4 AVC (MPEG-4 Part 10).[11]

Joint Collaborative Team on Video Coding[edit]

Joint Collaborative Team on Video Coding (JCT-VC) is a group of video coding experts from ITU-T Study Group 16 (VCEG) and ISO/IEC JTC 1/SC 29/WG 11 (MPEG). It was created in 2010 to develop High Efficiency Video Coding, a new generation video coding standard that further reduces (by 50%) the data rate required for high quality video coding, as compared to the current ITU-T H.264 / ISO/IEC 14496-10 standard.[12][13] JCT-VC is co-chaired by Jens-Rainer Ohm and Gary Sullivan.

Standards[edit]

The MPEG standards consist of different Parts. Each part covers a certain aspect of the whole specification.[14] The standards also specify Profiles and Levels. Profiles are intended to define a set of tools that are available, and Levels define the range of appropriate values for the properties associated with them.[15] Some of the approved MPEG standards were revised by later amendments and/or new editions. MPEG has standardized the following compression formats and ancillary standards:

MPEG-4 has been chosen as the compression scheme for over-the-air in Brazil (ISDB-TB), based on original digital television from Japan (ISDB-T).[23]

In addition, the following standards, while not sequential advances to the video encoding standard as with MPEG-1 through MPEG-4, are referred to by similar notation:

Moreover, more recently than other standards above, MPEG has started following international standards; each of the standards holds multiple MPEG technologies for a way of application.[24][25][26][27][28] (For example, MPEG-A includes a number of technologies on multimedia application format.)

Standardization process[edit]

A standard published by ISO/IEC is the last stage of a long process that starts with the proposal of new work within a committee. Here are some abbreviations used for marking a standard with its status:[3][49][50][51][52][53]

Other abbreviations:

A proposal of work (New Proposal) is approved at Subcommittee and then at the Technical Committee level (SC29 and JTC1 respectively – in the case of MPEG). When the scope of new work is sufficiently clarified, MPEG usually makes open requests for proposals – known as "Call for proposals". The first document that is produced for audio and video coding standards is called a Verification Model (VM). In the case of MPEG-1 and MPEG-2 this was called Simulation and Test Model, respectively. When a sufficient confidence in the stability of the standard under development is reached, a Working Draft (WD) is produced. This is in the form of a standard but is kept internal to MPEG for revision. When a WD is sufficiently solid, becomes Committee Draft (CD) (usually at the planned time). It is then sent to National Bodies (NB) for ballot. The CD becomes Final Committee Draft (FCD) if the number of positive votes is above the quorum. After a review and comments issued by NBs, FCD is again submitted to NBs for the second ballot. If the FCD is approved, it becomes Final Draft International Standard (FDIS). ISO then holds a ballot with National Bodies, where no technical changes are allowed (yes/no ballot). If approved, the document becomes International Standard (IS).[3]

ISO/IEC Directives allow also the so-called "Fast-track procedure". In this procedure a document is submitted directly for approval as a draft International Standard (DIS) to the ISO member bodies or as a final draft International Standard (FDIS) if the document was developed by an international standardizing body recognized by the ISO Council.[50]
