High efficiency video coding (HEVC) is the most recent video compression standard that doubled the coding efficiency as compared to the predecessor H.264/AVC. [] Key Method Class combination combines the four edge offset (EO) type into one. Pre-decision decreases the band offset (BO) search time from 29 to 4. Merge separation limits the merge range to saving the efficiency loss. Experimental result shows the proposed methods can saving about 38% SAO processing time with little degradation (BD-bitrate…
