The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications. Together with JPEG, MPEG is organized under ISO/IEC JTC 1/SC 29 – Coding of audio, picture, multimedia and hypermedia information (ISO/IEC Joint Technical Committee 1, Subcommittee 29).
MPEG formats are used in various multimedia systems. The most well known older MPEG media formats typically use MPEG-1, MPEG-2, and MPEG-4 AVC media coding and MPEG-2 systems transport streams and program streams. Newer systems typically use the MPEG and dynamic streaming (a.k.a. MPEG-DASH).
MPEG was established in 1988 by the initiative of Dr. Hiroshi Yasuda (NTT) and Dr. Leonardo Chiariglione (CSELT). Chiariglione was the group's chair (called Convenor in ISO/IEC terminology) from its inception until June 6, 2020. The first MPEG meeting was in May 1988 in Ottawa, Canada.
Starting around the time of the MPEG-4 project in the late 1990s and continuing to the present, MPEG had grown to include approximately 300–500 members per meeting from various industries, universities, and research institutions.
On June 6, 2020, the MPEG section of Chiariglione's personal website was updated to inform readers that he had retired as Convenor, and he said that the MPEG group (then SC 29/WG 11) "was closed". Chiariglione described his reasons for stepping down in his personal blog. His decision followed a restructuring process within SC 29, in which "some of the subgroups of WG 11 (MPEG) [became] distinct MPEG working groups (WGs) and advisory groups (AGs)" in July 2020. Prof. Jörn Ostermann of University of Hannover was appointed as Acting Convenor of SC 29/WG 11 during the restructuring period and was then appointed Convenor of SC 29's Advisory Group 2, which coordinates MPEG overall technical activities.

Study of the essential components and implementation technologies of digital signal processing and communication systems from the theoretical, algorithmic and system implementation point of view.
This course covers fundamental notions in image and video processing, as well as covers most popular tools used, such as edge detection, motion estimation, segmentation, and compression. It is compose
The goal of this course is to introduce the engineering students state-of-the-art speech and audio coding techniques with an emphasis on the integration of knowledge about sound production and auditor
Blu-ray (Blu-ray Disc or BD) is a digital optical disc data storage format. It was invented and developed in 2005 and released worldwide on June 20, 2006. It was designed to supersede the DVD format, capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X.
MPEG-1 is a standard for lossy compression of video and audio. It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical. Today, MPEG-1 has become the most widely compatible lossy audio/video format in the world, and is used in a large number of products and technologies.
MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264/AVC and H.
Omnidirectional video streaming is usually implemented based on the representations of tiles, where the tiles are obtained by splitting the video frame into several rectangular areas and each tile is converted into multiple representations with different r ...
