Abstract

The Versatile Video Coding (VVC) is a new state-of-the art video compression technology that is being under standardization. It targets for about two times higher coding efficiency against the existing HEVC, supporting HD/UHD/8K video and high dynamic range (HDR) video. It also targets for versatilities such as screen content coding, adaptive resolution change, and independent sub-pictures. To develop an effective coding method for chroma intra prediction mode, in this paper, we investigate its binarization process in CABAC (context adaptive binary arithmetic coding) and test a method which assigns shorter bins to more frequent chroma intra modes and longer bins to the less frequent ones based on the chroma mode statistics.
