Video Quality Comparison of H.264/AVC and AVS in High Fidelity Profiles

The recently developed Audio and Video Coding Standard (AVS) developed by AVS Workgroup of China has similar coding efficiency as the H.264/AVC but with a much less complexity. Question on whether the visual quality of the less complex AVS is as good as the H.264 counterpart arises. To answer this question, objective and subjective comparisons of AVS-P2 X profile and H.264/AVC high profile are made, and the results are presented in this paper. The results show that the performances of both video coding systems are similar in terms of objective rate-distortion performance and subjective visual quality.
