MPEG Full Form - 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 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
