'''Audio Video Coding Standard''' ('''AVS''') refers to the digital audio and digital video series compression standard formulated by the Audio and Video coding standard workgroup of China. Work began in 2002, and three generations of standards were published.<ref>{{cite web |title= Youwei Vision launches AVS3 8K video real-time decoder (in Chinese) |date= May 29, 2019  |url= https://mp.weixin.qq.com/s/0sc4XsABtNpha5kcHr1meg |website= Tencent }}</ref>

The first generation AVS standard includes "Information Technology, Advanced Audio Video Coding, Part 2: Video" ('''AVS1''') and "Information Technology, Advanced Audio Video Coding Part 16: Radio Television Video" ('''AVS+'''.) For the second generation, referred to as '''AVS2''', the primary application target was [[ultra-high-definition television]] video, supporting the efficient compression of ultra-high-resolution ([[4K resolution|4K]] and above), [[high-dynamic-range video]]s, and was published as IEEE international standard IEEE 1857.4. An industry alliance was established to develop and promote AVS standards.<ref>{{cite web|title=Introduction to AVSA|url=http://www.avsa.org.cn/|website=Official website of AVSA|access-date=September 29, 2017|archive-url=https://web.archive.org/web/20190324050204/http://www.avsa.org.cn/|archive-date=March 24, 2019}}</ref> A patent pool charges a small royalty for terminal products (like TVs,) excluding content providers and operators.<ref>{{cite web|title=Who will lead the new video coding standard: a performance comparison report of HEVC、AVS2 and AV1|url=http://media.pkusz.edu.cn/achievements/?p=138|access-date=September 29, 2017|archive-url=https://web.archive.org/web/20180728191424/http://media.pkusz.edu.cn/achievements/?p=138|archive-date=July 28, 2018}}</ref>
