Audio Video Coding Standard (AVS) refers to the digital audio and digital video series compression standard formulated by Audio and Video coding standard workgroup of China according to the open international rules. Formulation of 3-generation AVS standards has been completed.
The first generation AVS standard includes “Information Technology, Advanced Audio Video Coding, Part 2: Video” (AVS1 for short) and “Information Technology, Advanced Audio Video Coding Part 16: Radio Television Video” (AVS+ for short).
For the second generation AVS standard, referred to as AVS2, the primary application target is Ultra HD (high definition) video, supporting the efficient compression of ultra-high-resolution (4K above), HDR (high dynamic range) videos, and it has been submitted to the IEEE international standard (Standard No.: IEEE1857.4) for application.
The "AVS patent pool" provides authorization for the AVS standard, which charges only a small amount of royalties for terminal products (like TVs), excluding content providers and operators. The royalty for the first generation AVS standard is one yuan per terminal.
In order to propel the development and promotion of the AVS standard, Huawei, TCL, Skyworth and other companies established Zhongguancun audiovisual industry technology innovation alliance (abbreviation: AVS industry alliance), which is devoted to the development and promotion of the AVS standard.
