Title
Intra coding of AVS2 Video Coding Standard
Abstract
This paper gives an introduction to intra coding of the new generation of Audio Video Coding Standard (AVS2) video part, the latest video coding standard under the development of Audio Video Coding Standard (AVS) Workgroup of China. Started from the basic tools in the first generation of AVS (AVS1), new structures similar to the HEVC are employed in AVS2 in terms of coding unit, prediction unit and transform unit. Despite of similar structures, several new features such as short distance intra coding, non-squared quad-tree transform, secondary transform as well as two-level coefficient coding combined with angular prediction are also adopted in intra coding of AVS2. The coding efficiency of intra coding of AVS2 is improved by about 30% in BD-rate compared with AVS1 and achieves the similar performance to HEVC/H.265.
