Abstract: Versatile video coding (VVC), which is the next generation video coding standard, is being developed to provide greater coding efficiency than existing video coding standards. In VVC, various coding tools related to intra and inter prediction modes have been adopted. This paper introduces several methods that improve coding efficiency or reduce computational complexity on top of VVC adopted tools. The first method enhances the most probable mode list derivation with the statistics of the intra modes of neighbouring blocks. The second method reduces the number of contexts of the merge with motion vector difference mode. The third method excludes invalid block vector predictors early for the intra block copy mode to improve block vector coding. The experimental results show that the three proposed methods show coding efficiencies of −0.05% for all intra coding, −0.02% for random access, and −0.14% for random access coding scenarios, respectively.
