Michael J. Horowitz

Michael J. Horowitz (born January 2, 1964, in Ames, Iowa) is an American electrical engineer who actively participated in the creation of the H.264/MPEG-4 AVC and H.265/HEVC video coding standards. He is co-inventor of flexible macroblock ordering (FMO) ^[1] and tiles,^[2] essential features in H.264/MPEG-4 AVC and H.265/HEVC, respectively. He is managing partner of Applied Video Compression and has served on the technical advisory boards of Vivox, Inc., Vidyo, Inc., and RipCode, Inc.

Education

• A.B. degree with distinction in physics from Cornell University, Ithaca, New York, 1986.
• M.S. degree in electrical engineering from Columbia University, New York, New York, 1988.
• Ph.D. in electrical engineering from The University of Michigan, Ann Arbor, 1998.

Professional work

Horowitz also has contributed to the early productization of several video coding standards:

• 2000 – At Polycom, architect and developer of the first commercially available in-product implementation of macroblock-adaptive multiple reference frames (H.263 Annex U).^[3] Macroblock-adaptive multiple reference frames has become a mainstay in subsequent video coding standards.
• 2003 – At Polycom, architect and lead engineer of the team that produced the first commercially available in-product implementation of H.264/AVC.^[4]
• 2008 – At Vidyo, architect and lead engineer of the team that developed the first commercially available in-product implementation of H.264 SVC^[5]
• 2012 – At eBrisk Video, architect and lead engineer of the team that developed one of the first commercially available implementations of H.265/HEVC.^[6]
• 2020 – At Google, Technical Lead of the AV1 for Duo project that became the first commercially available real-time interactive video implementation of AV1.^[7]
