This paper proposes a parallelization method for a deblocking filter in a high-efficiency video coding (HEVC) decoder based on complexity estimation. A deblocking filter of HEVC is generally considered to be appropriate for data-level parallelism (DLP) because there are no data-level dependencies among adjacent blocks in the horizontal and vertical filtering processes. However, an imbalanced workload...
This paper proposes an adaptive intra mode selection algorithm with rough mode decision (RMD) stage and an early termination for rate-distortion optimization (RDO) stage for fast intra coding of High Efficiency Video Coding (HEVC). The proposed adaptive mode selection for fast intra coding employs the prediction modes from the upper layer of coding unit (CU) and neighboring prediction units (PUs)...
This paper presents a new hybrid parallelization method for High Efficiency Video Coding (HEVC) decoder. The proposed method groups HEVC decoding modules into entropy decoding, pixel decoding, and in-loop filtering parts for optimal parallelization considering the characteristic of all the parts. The proposed method employs coding tree unit (CTU)-level 2D wavefront for the pixel decoding part. To...
