Abstract
In this paper we propose and evaluate a parallelization strat-egy for the emerging HEVC video coding standard. The pro-posed strategy is based on entropy slices which allows ex-ploiting parallelism in the entropy decoding stage while main-taining high coding efficiency. Our approach requires to en-code videos with one entropy slice per LCU row in order to decode multiple LCU rows in a wavefront parallel manner. Evaluations performed on a PC with 12 Intel Xeon cores run-ning at 3.3 GHz show that it is possible to achieve real-time performance for 1920×1080p50 (53.1 fps) and 2560×1600 (29.5fps) video resolutions with speedups of 5.2 × and 6.3× compared to sequential execution, respectively. Index Terms — HEVC, video codecs, parallel processing, high definition video.
