Michael J. Horowitz

American electrical engineer (born 1964)

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

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]

Standardization

  • 2001-2002 – VCEG Chair, Ad hoc Group on H.26L Complexity Reduction
  • 2002-2003 – JVT Chair, Ad hoc Group on H.26L Complexity Reduction
  • 2002-2003 – JVT Chair, Ad hoc Group on Robustness
  • 2008-2010 – VCEG Chair, Ad hoc Group on Computational Efficiency
  • 2011-2012 – JCT-VC Chair, Ad hoc Group on High-level Parallelism
  • 2020 – Alliance for Open Media Co-chair, RTC Subgroup
