Gary Joseph Sullivan (born 1960) is an American electrical engineer who led the development of the H.264/MPEG-4 AVC and HEVC video coding standards and created the DirectX Video Acceleration (DXVA) API/DDI video decoding feature of the Microsoft Windows operating system. He was the chairman of the Joint Video Team (JVT) standardization committee that developed the H.264/AVC standard, and he personally edited large portions of it. Since January 2010, he has been a co-chairman of the Joint Collaborative Team on Video Coding (JCT-VC) and an editor for developing the High Efficiency Video Coding (HEVC) standard, and since July 2012 has been co-chairman of the Joint Collaborative Team on 3D Video (JCT-3V) that works on standardization of 3D video coding. He has also led and contributed to a number of other video and image related standardization projects such as extensions of ITU-T H.263 video coding and the standardization of JPEG XR image coding, and has published research work on various topics relating to video and image compression. ==Biography== Sullivan was born and raised in Louisville, Kentucky, and attended the Ascension and St. Margaret Mary elementary schools and Trinity High School, graduating in 1978. He received B.S. and M.Eng. degrees in electrical engineering from the University of Louisville J. B. Speed School of Engineering, Kentucky, in 1982 and 1983, respectively. He received Ph.D. and Engineer degrees in electrical engineering from the University of California, Los Angeles, in 1991. Sullivan holds the position of Video and Image Technology Architect at Microsoft Corporation.〔(Data Compression Conference (DCC 2013) ), March 2013.〕〔(Gary J.
