Abstract: Ultra-High Definition (UHD) Videos can provide users a higher quality and more immersive visual experiences. However, the application of UHD is limited by high bandwidth cost. To solve the transmission and storage problem of UHD, China Audio and Video Coding Standard（AVS）workgroup established a new generation of video coding standard—AVS3. Currently, AVS3 has made a great contribution to the development of UHD industries in China. Key technologies of AVS3 are described, and a comprehensive comparison with AVS2、versatile video coding(VVC) and alliance for open media video 1 (AV1) is conducted.
