Abstract: In this paper we propose and evaluate a parallelization strategy for the emerging HEVC video coding standard. The proposed strategy is based on entropy slices which allows exploiting parallelism in the entropy decoding stage while maintaining high coding efficiency. Our approach requires to encode 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 running 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.
