Moving Picture Experts Group - Wikipedia. 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 authorities that was formed by ISO and IEC to set standards for audio and video compression and transmission.[1] It was established in 1. Hiroshi Yasuda (Nippon Telegraph and Telephone) and Leonardo Chiariglione,[2] group Chair since its inception. The first MPEG meeting was in May 1.

Ottawa, Canada.[3][4][5] As of late 2. MPEG has grown to include approximately 3. MPEG's official designation is ISO/IEC JTC 1/SC 2. WG 1. 1 – Coding of moving pictures and audio (ISO/IEC Joint Technical Committee 1, Subcommittee 2. Working Group 1. 1).[6][7][8][9]Sub Groups[edit]ISO/IEC JTC1/SC2. WG1. 1 – Coding of moving pictures and audio has following Sub Groups (SG): [6]Requirements. Systems. Video. Audio.

Question 6) – VCEG (Video Coding Experts Group) and ISO/IEC JTC1/SC2. WG1. 1 – MPEG for the development of new video coding recommendation and international standard.[6][1.

It was formed in 2. H. 2. 64/MPEG- 4 AVC (MPEG- 4 Part 1. 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 1. VCEG) and ISO/IEC JTC 1/SC 2.

WG 1. 1 (MPEG). It was created in 2. High Efficiency Video Coding, a new generation video coding standard that further reduces (by 5. ITU- T H. 2. 64 / ISO/IEC 1. 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.[1. 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.[1. 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- 1 (1. Coding of moving pictures and associated audio for digital storage media at up to about 1. Mbit/s (ISO/IEC 1. This initial version is known as a lossy fileformat and is the first MPEG compression standard for audio and video. It is commonly limited to about 1.

Mbit/s although the specification is capable of much higher bit rates. It was basically designed to allow moving pictures and sound to be encoded into the bitrate of a Compact Disc. It is used on Video CD and can be used for low- quality video on DVD Video. It was used in digital satellite/cable TV services before MPEG- 2 became widespread. To meet the low bit requirement, MPEG- 1 downsamples the images, as well as uses picture rates of only 2. Hz, resulting in a moderate quality.[1.

As many readers will know, Duxford played a major role in filming the motion picture The Battle of Britain during 1968 which once again saw Spitfires and Hurricanes.

It includes the popular MPEG- 1 Audio Layer III (MP3) audio compression format. MPEG- 2 (1. 99. 5): Generic coding of moving pictures and associated audio information (ISO/IEC 1.

Transport, video and audio standards for broadcast- quality television. MPEG- 2 standard was considerably broader in scope and of wider appeal – supporting interlacing and high definition.

MPEG- 2 is considered important because it has been chosen as the compression scheme for over- the- air digital television. ATSC, DVB and ISDB, digital satellite TV services like Dish Network, digital cable television signals, SVCD and DVD Video.[1. It is also used on Blu- ray Discs, but these normally use MPEG- 4 Part 1. SMPTE VC- 1 for high- definition content. MPEG- 3: MPEG- 3 dealt with standardizing scalable and multi- resolution compression[1.

HDTV compression but was found to be redundant and was merged with MPEG- 2; as a result there is no MPEG- 3 standard.[1. MPEG- 3 is not to be confused with MP3, which is MPEG- 1 or MPEG- 2 Audio Layer III.

MPEG- 4 (1. 99. 8): Coding of audio- visual objects. ISO/IEC 1. 44. 96) MPEG- 4 uses further coding tools with additional complexity to achieve higher compression factors than MPEG- 2.[1. In addition to more efficient coding of video, MPEG- 4 moves closer to computer graphics applications. In more complex profiles, the MPEG- 4 decoder effectively becomes a rendering processor and the compressed bitstream describes three- dimensional shapes and surface texture.[1. MPEG- 4 supports Intellectual Property Management and Protection (IPMP), which provides the facility to use proprietary technologies to manage and protect content like digital rights management.[1. It also supports MPEG- J, a fully programmatic solution for creation of custom interactive multimedia applications (Java application environment with a Java API) and many other features.[2.

Several new higher- efficiency video standards (newer than MPEG- 2 Video) are included, notably. 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).[2. 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: MPEG- 7 (2.

Multimedia framework (MPEG- 2. ISO/IEC 2. 10. 00) MPEG describes this standard as a multimedia framework and provides for intellectual property management and protection. 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.[2.
