MPEG is a working group of ISO, the International Organization for Standardization. Its formal name is ISO/IEC JTC 1/SC 29/WG 11. The title is: Coding of moving pictures and audio. The work assigned to it is: Development of international standards for compression, decompression, processing, and coded representation of moving pictures, audio, and their combination, in order to satisfy a wide variety of applications. The standards So far MPEG has produced can be found here.

MPEG has attracted a large number of researchers from both industry and academia because it has succeeded to respond to the needs for standards coming from the industry with the enthusiasm and dedication of MPEG delegates.
MPEG usually holds four meetings a year. These comprise plenary meetings and subgroup meetings on Requirements, Systems, Video, Audio and 3D Graphics. Participation is open to experts duly accredited by an appropriate National Standards Body. On average a meeting is attended by more than 300 experts from some 20 countries representing more than 200 companies spanning all industry domains with a stake in digital audio, video and multimedia.
Attendance at MPEG meetings requires accreditation by a National Standards Body or standards committee in liaison. Experts attending MPEG not representing a committee in liaison must be members of a National Delegation under the responsibility of a Head of Delegation appointed by the National Body.
