In this paper, a fast transcoding solution from H.264/AVC to HEVC bitstreams is presented. This solution is based on two main modules: a coding unit (CU) classification module that relies on a machine learning technique in order to map H.264/AVC macroblocks into HEVC CUs; and an early termination technique that is based on statistical modeling of the HEVC rate-distortion (RD) cost in order to further speed-up the transcoding. The transcoder is built around an established two-stage transcoding… CONTINUE READING
