The Alliance for Open Media (AOMedia) is a non-profit industry consortium for the development of open, royalty-free technology for multimedia delivery headquartered in Wakefield, Massachusetts, USA. It adopts the principles of the development of open web standards for the creation of video standards that can serve as royalty-free alternatives to the hitherto dominant standards of the Moving Picture Experts Group (MPEG) and the related business model that exploits intellectual property through patent royalties and became associated with financial uncertainties, especially for internet companies and innovators.[3][4][5]

Its first project was to develop AV1, a new open video codec and format as a successor to VP9 and a royalty-free alternative to HEVC[1][2], which uses elements from Daala, Thor, and VP10.[6]

The governing members are Amazon, Apple, ARM, Cisco, Facebook, Google, IBM, Intel Corporation, Microsoft, Mozilla, Netflix, Nvidia and Samsung Electronics.[7]



Some collaboration and some work that would later be merged into AV1 predates the official launch of the Alliance.[3] Following the successful standardization of an audio standard in the Internet Engineering Task Force (IETF) in 2012, a working group for the standardization of a royalty-free video format began to form under the lead of people from the Foundation,[8] who had begun working on their experimental video format Daala back in 2010.[9] In May 2015, the Internet Video Codec working group (NetVC) of the IETF was officially started and presented with coding techniques from Xiph's/Mozilla's Daala.[10] Cisco Systems joined forces and offered their own prototype format Thor to the working group on July 22.[11] People were left wondering about the absence and silence of Google who has invested heavily in an open video format for the web with its VP8, VP9, and WebM Project.

The lack of a suitable video format that made the W3C end up not putting a video format in the specification for HTML5[12] and the failed negotiations for one mandatory video format for WebRTC showed need for a competitive open video standard. The emergence of a second patent pool for HEVC (HEVC Advance) in spring 2015 provided some important motivational background for investments in an alternative video format and growing support the Alliance because it spread uncertainty regarding royalties for MPEG's next-generation video format.[13]

On September 1, 2015, the Alliance for Open Media was announced with the goal of developing a royalty free video format as an alternative to licensed formats such as H.264 and HEVC.[1][14][2] The founding members are Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and Netflix.[1][2] The plan was to release the video format by 2017.[2][15]

The alliance saw expansion of its member list since inception. On April 5, 2016, the Alliance for Open Media announced that AMD, ARM, and Nvidia had joined, and[16] Adobe, Ateme, Ittiam and Vidyo joined in the months following.[17][18][19][20] Facebook later joined as a governing member, and in 2018 the alliance's website was quietly updated to add Apple as a governing member of the alliance.[21]

In 2018, the founder and chairman of the MPEG acknowledged the Alliance to be the biggest threat to their business model, furthermore stating that:[22]

Alliance for Open Media has occupied the void created by MPEG’s outdated video compression standard (AVC), absence of competitive [royalty free] standards (IVC) and unusable modern standard (HEVC)... Everybody realises that the old MPEG business model is now broke.

AOMedia VideoEdit

The Alliance's first project is the creation of a next-generation state of the art open video compression format and codec that is optimized for streaming media over the internet, for both commercial and non-commercial content, including user-generated content.[16] A line of new video formats named AOMedia Video (AV) is being developed.[16][23] Alliance members from the chip industry (AMD, ARM, Intel, Nvidia) are meant to ensure hardware-friendly design.

AOMedia planned for the first version of its format (AV1) to be completed before the end of 2017.[24] However, work on the bitstream specification will be continued in 2018.[25] It is assumed to get rapid adoption and is the primary contender for standardisation by the video coding standard working group NetVC of the Internet Engineering Task Force (IETF).[26]

Main distinguishing features of AV1 are its royalty-free licensing terms and state of the art performance. AV1 is specifically designed for real-time applications and for higher resolutions than typical usage scenarios of the current generation (H.264) of video formats.[27]

Operation and structureEdit

The Alliance is incorporated in the USA as a tax-exempt non-profit organization and a subsidiary "project" of the independent Joint Development Foundation (JDF) that's also headquartered in Wakefield.

The Alliance will release new video codecs as free software under the BSD 2-Clause License. It adopted the patent rules of the W3C[4] which mandate technology contributors to disclose all patents that may be relevant and to agree to a royalty-free patent license.[28] The Alliance's patent license contains a defensive termination clause to discourage patent lawsuits.

Software development happens in the open[23] using a public source code repository[27] and issue tracking system, and welcomes contributions from the general public. Contributions have to pass internal reviews and gain consensus for their adoption. Different sub-groups inside the Alliance handle testing, reviews for IPR/patent problems[4][29] and hardware-friendliness[30], and editing of specification documents.[31]

There are two levels of membership: Organizations can join as an ordinary member, or as a governing member with a seat on the board of directors. Confusingly, these are dubbed "founding members" in AOM terminology, although they need not be members since the Alliance was founded.

There is a broad representation of the video industry among the Alliance members, featuring several hardware, software, and content producers, OTT video distributors, providers of real-time conferencing solutions, and browser vendors. Several AOM members have previously worked on MPEG's HEVC and hold patents to it (e.g. BBC, Intel, Cisco, Vidyo, Apple, Microsoft, and Broadcom[32]).
