 Moving Picture Experts Group

Moving Picture Experts Group

  • MPEG stands for Moving Picture Experts Group.
  • It’s a working party of authorities which is established to line standards for audio and video compression and transmission.
  • It develops audio video file formats which are referred to as MPEG.
  • This group is made by International organization for Standardization ( ISO ) and International Electrotechnical Commission (IEC).
  • It’s released various versions of file (standards) namely MPEG-1, MPEG-2, MPEG-3, MPEG-4, MPEG-7, MPEG-21 etc.
  • The MPEG standard may be a set of specification for compressed audio and video file.
  • It’s designed for storing video on Digital Audio Tapes (DAT) and audio files on standard audio compact disk ( CD ).
  • The MPEG file has ".mpeg" as a file extension. In the past, the MPEG files required hardware decoder for storing and playback but today, it requires software-only codecs.
  • MPEG was established in January 1988 by the initiative and help of Leonardo Chiariglione and Hiroshi Yasuda.
  • Its first meeting was held in Ottawa, Canada in May 1988.
  • Since, 1988, it's produced various standards that helped industry offer users more enjoyable digital media experience.
  • Over the years, since its inception, it's grown to an outsized ISO working party.
  • Today, around 350 experts from some 200 companies from more than 20 countries participate in MPEG meetings. Its meetings are held four times during a year within the months of January, April, July and October.

How Does MPEG WORK ?

  • The MPEG algorithm compresses the data to small bits.
  • These bits are often easily transmitted and decompressed then the video is encoded through a way called Discrete Cosine Transform (DCT).
  • The compression rate of MPEG is extremely high because it stores only the changes that occur from one frame to a different frame.
  • It doesn't store the entire frame that permits it reduce the dimensions of overall file.
 Step to Develop

Step to develop MPEG

  • MPEG generally follows the following steps to develop a standard:
    • Identify the need of a standard
    • Collect the requirements
    • Call for proposals
    • Evaluate the proposals
    • Technical development
