Proposed as a national standard in 2004, Audio Video Standard is a compression audio and video system developed by the Audio Video Coding Standard Workgroup of China. Designed to replace AAC audio and H.264/MPEG-4 AVC at a lower price than commonly used systems in the rest of the world. It is not much used outside China. AVS+ was designed to provide performance with reduced complexity.
In 2013 work started on AVS2: designed to compete with HEVC(H.265).
