Web15 de mai. de 2011 · The coding unit which is larger than 16 × 16 and less than or equal to 64 × 64 provides great bit rate saving while the coding complexity increases dramatically. In this paper, we propose a fast coding unit decision algorithm in either frame level or coding unit level to accelerate encoding procedure. WebH.265/HEVC supports two types of frame coding structures including random access (RA) and low delay (LD) , where different frames form a set of hierarchical structures within a group-of-picture (GOP) and the frames at a higher coding layer can be predicted from one or more frames at lower coding layers.
