- High Efficiency Video Coding (HEVC) has brought significant improvement to video compression in terms of coding performance and subjective quality. However, it is computationally more complex than H.264/Advanced Video Coding (AVC) and, hence, adaptation of HEVC to real-time video services has not been promising. In order to reduce the computational cost, we propose a fast mode decision method that is based on the adaptive ordering of modes. Our experimental results show that the proposed method reduces the total encoding time by 47.27%-60.73% and 47.65%-61.31%, with negligible degradation of coding performance, which is a Bj첩ntegaard delta rate increment of 0.35%-1.04% and 0.64%-1.80% under randomaccess configuration and low-delay configuration, respectively, compared with HEVC test model 12.1 with fast mode off.
