Abstract:

Versatile Video Coding（VVC） is the next generation video codec standard, during the development of new standards, many new technologies have been added to improve encoding performance, but new technologies increase encoding complexity. In view of this situation, through the study of the inter-frame prediction unit partition algorithm in the new standard encoding process, it is found that redundant deeper partition is performed when VVC inter-frame units are partitioned, this algorithm increases coding complexity, so this paper proposes a fast inter-frame prediction algorithm with limitation on the partition level, which makes the unit partition end early, and avoids unnecessary partition levels. Experimental results show that under the RA configuration, the new algorithm increases the compression rate by 1.58% and loses the image distortion of 0.0362, but the encoding complexity is reduced by 46.39%. Therefore, the optimization algorithm can effectively reduce the encoding complexity.
