High Efficient Video Coding (HEVC) is the newest global video coding standard announced in 2013. More and more codings are migrating from H.264\/AVC to HEVC because of its higher compression performance. In this paper, we propose an efficient HEVC to AVS2 transcoding algorithm, which applies a multi-stage decoding information utilization framework to maximize the usage of the decoding information in the transcoding process. The proposed algorithm achieves 11\u00d7\u201317\u00d7 speed gains over the AVS2 reference software RD 14.0 with a modest BD-rate loss of 9.6%\u201316.6%.<\/jats:p>","DOI":"10.3390\/info7030053","type":"journal-article","created":{"date-parts":[[2016,9,19]],"date-time":"2016-09-19T10:07:43Z","timestamp":1474279663000},"page":"53","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Efficient Software HEVC to AVS2 Transcoding"],"prefix":"10.3390","volume":"7","author":[{"given":"Yucong","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Computer Science and Technology, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun","family":"Zhou","sequence":"additional","affiliation":[{"name":"Academy of Broadcasting Science, State Administration of Press, Publication, Radio, Film and Television of The People\u2019s Republic of China (SAPPRFT), Beijing 100045, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiangtao","family":"Wen","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Technology, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,9,19]]},"reference":[{"unstructured":"Fan, L., Ma, S., and Wu, F.
