Coding efficiency comparison of new video coding standards: HEVC vs VP9 vs AVS2 video

In this paper, coding efficiency comparisons of emerging video codecs, HEVC, VP9 and AVS2 Video, are conducted. The purpose of this paper is to provide useful information about the current state-of-the-art video codecs and to help both academia and industry to get insight for developing advanced techniques on top of them. At first, design differences among the three video codecs are given briefly and then coding efficiency comparisons are conducted in random access and low delay condition. According to experimental results, HEVC outperforms VP9 and AV2 video by 24.9% and 6.5% in random access condition, respectively. In low delay condition, HEVC also outperforms VP9 and AVS2 video by 8.7% and 14.5%, respectively.
