The second generation of Audio and Video coding Standard (AVS) is developed by the\nIEEE 1857 Working Group under project 1857.4 and was standardized in 2016 by the AVS Working\nGroup of China as the new broadcasting standard AVS2. High Efficient Video Coding (HEVC) is\nthe newest global video coding standard announced in 2013. More and more codings are migrating\nfrom H.264/AVC to HEVC because of its higher compression performance. In this paper, we propose\nan efficient HEVC to AVS2 transcoding algorithm, which applies a multi-stage decoding information\nutilization framework to maximize the usage of the decoding information in the transcoding process.\nThe proposed algorithm achieves 11Ã?â??ââ?¬â??17Ã?â?? speed gains over the AVS2 reference software RD 14.0\nwith a modest BD-rate loss of 9.6%ââ?¬â??16.6%.
