Performance Exploration of Jointly Rate-Distortion Optimized HEVC Intra Encoder

Yingwen Zhang, Meng Wang, Junru Li, Shiqi Wang

Abstract: We extend the beam-search based joint rate-distortion optimization (BSJRDO) [1] to High Efficiency Video Coding (HEVC) and investigate the impact of different decisions on it. In BSJRDO, unlike the greedy search, which only maintains one locally optimal path at each decision stage, multiple paths are kept as candidates for future referencing.
