Paper Abstract

In this paper, we propose an inter-frame coding unit (CU) prediction mode fast decision and block partition early termination algorithm for versatile video coding (VVC), to reduce the computational complexity of its encoder. By analyzing the difference of rate-distortion cost (RD-Cost) between different coding depths, the redundant prediction mode can be skipped quickly. In addition, through the analysis of the relationship between the final partition depth of the inter-frame CU and the prediction modes, the continuous downward recursive partition of the current CU is terminated by comparing the RD-Cost among the prediction modes. The experimental results show that our proposed algorithm can save 30.34% encoding time with 0.92% BD-Rate loss on average compared with the standard algorithm called Joint Exploration Model (JEM) 7.0.
