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.^[1]

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 and above), high-dynamic-range videos, and was published as IEEE international standard IEEE 1857.4. An industry alliance was established to develop and promote AVS standards.^[2] A patent pool charges a small royalty for terminal products (like TVs,) excluding content providers and operators.^[3]

The AVS3 codec was added to DVB's media delivery toolbox.^[4]
