Versatile Video Coding (VVC), which mainly introduces the QTMT partition structure and introduces new technologies in inter coding and intra coding, greatly improves the coding efficiency compared with the previous generation video coding standard. However, the improvement in coding efficiency comes at the cost of a huge increase in coding complexity. In order to reduce the computational complexity of VVC, this paper proposes a fast skip coding unit (CU) inter prediction algorithm in the VVC encoder. The algorithm mainly uses the difference bet...
