The Alliance for Open Media ( AOMedia ) is a nonprofit industry consortium for the development of open royalty free technology for multimedia delivery based in Wakefield, Massachusetts, USA. It adopts the principles of developing open web standards for the creation of video standards that can serve as royalty free alternatives to the now dominant standards of the Moving Image Experts Group (MPEG) and related business models that exploit intellectual property through patents. royalty and become associated with financial uncertainty, especially for internet companies and innovators.
His first project was to develop a new AV1, codec and video format instead of VP9 and a royalty-free alternative to HEVC that uses elements from Daala, Thor, and VP10.
The governing members are Amazon, Apple, ARM, Cisco, Facebook, Google, IBM, Intel Corporation, Microsoft, Mozilla, Netflix, and Nvidia.

Histori
Some collaborations and some work that will later be merged into AV1 ahead of the official launch of the Alliance. Following the successful standardization of audio standards in the Internet Engineering Task Force (IETF) in 2012, a working group to standardize royalty-free video formats began to form under the leadership of the people of the Xiph.org Foundation, who have begun working on their experimental video format Daala in 2010. In May 2015, the IETF Codec Video Internet (NetVC) working group officially started and presented with coding techniques from Daalas by Xiph/Mozilla. Cisco Systems merged and offered their own Thor prototype format to the working group on July 22. People are wondering about Google's absence and silence that has invested in an open video format for the web with VP8, VP9, ​​â € <â € The lack of an appropriate video format that makes W3C ultimately do not put video formats in specification for HTML5 and negotiations failing for a mandatory video format for WebRTC demonstrating the need for competitive open video standards. The emergence of a second patent pool for HEVC (HEVC Advance) in spring 2015 provides some important motivational background for investing in alternative video formats and supports Alliance support for spreading uncertainty about royalties for the next generation MPEG video format. On September 1, 2015, Alliance for Open Media was announced with the aim of developing a royalty-free video format as an alternative to licensed formats like H.264 and HEVC. Founding members are Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and Netflix. The plan is to release a video format in 2017. The Alliance sees its member list expansion from the start. On April 5, 2016, Alliance for Open Media announced that AMD, ARM, and Nvidia have merged, and Adobe, Ateme, Ittiam and Vidyo joined in the months that followed. Facebook then joins as a governing member, and by 2018 the alliance's website is quietly updated to add Apple as a member who governs the alliance. In 2018, MPEG founder and chairman recognizes the Alliance being the biggest threat to their business model, further stating that:
The Alliance for Open Media has occupied a vacuum created by outdated MPEG video compression standards (AVC), the absence of competitive standards (royalty free) (IVC) and unusable modern standards (HEVC)... Everyone is aware of that the old MPEG business model is now breaking out.

AOMedia Video
The Alliance's first project is the creation of advanced, advanced compression formats and video formats optimized for streaming media over the internet, both for commercial and non-commercial content, including user-generated content. A new video format called AOMedia Video (AV) is being developed. Alliance members from the chip industry (AMD, ARM, Intel, Nvidia) are intended to ensure a hardware-friendly design.
AOMedia is planning for the first version of the format (AV1) to be completed before the end of 2017. However, working on the bitstream specification will resume in 2018. It is assumed to get rapid adoption and is a major competitor to standardize by NetVC standard group video coding from Internet Engineering Task Force (IETF).
AV1's key differentiator feature is its royalty-free license terms and art performance status. AV1 is designed specifically for real-time applications and for higher resolutions than the typical current generation (H.264) usage scenarios of video formats.
Operation and structure
The alliance is incorporated in the US as a tax-free nonprofit organization and a subsidiary "project" of the independent Joint Development Foundation (JDF) which is also headquartered in Wakefield.
The Alliance will release new video codecs as free software under the BSD 2-Klausa License. It adopts the patent rules of the W3C which mandate tech contributors to disclose all patents that may be relevant and consent to a royalty-free patent license. The Alliance's patent license contains defensive termination clauses to prevent patent lawsuits.
Software development takes place in the open using public source code repositories and problem tracking systems, and receives contributions from the general public. Contributions must go through internal reviews and gain consensus for their adoption. Different subgroups within the Alliance handle testing, reviews for IPR/patent issues and hardware friendliness, and editing of specification documents.
There are two levels of membership: Organizations can join as regular members, or as members who organize with seats on the board of directors. Confusingly, it's nicknamed "founding members" in AOM terminology, although they do not have to be members since the Alliance was founded.
There is a widespread representation of the video industry among Alliance members, featuring multiple hardware, software, and content manufacturers, OTT video distributors, real-time conference conferencing providers, and browser vendors. Some AOM members have previously worked on HEVC MPEG and hold patents for it (eg BBC, Intel, Cisco, Vidyo, Apple, Microsoft, and Broadcom).
