Abstract

In VVC, the intra prediction mode of a block is encoded using the most probable mode (MPM). For this purpose, possible candidate modes for MPM are maintained in the MPM candidate list. The list is constructed differently depending on the number of neighboring angular intra prediction modes. While it is important to maintain a proper MPM candidate list, but how to encode the selected list index is also important. In this paper, we investigate on context coding of the MPM candidate list index instead of the current bypass-coding in VVC. The proposed method achieves a BDBR gain of 0.08% in the Y channel, and 0.10% and 0.06% respectively in the Cb and Cr channels.
