We present a novel video codec for supporting entertainment-quality video. It has new coding tools such as an intra prediction with offset, integer sine transform, and enhanced block-based adaptive loop filter. These tools are used adaptively in the processing of intra prediction, transform, and loop filtering. In our experiments, the proposed codec achieved an average reduction of 13.35% in BD-rate relative to H.264/AVC for 720p sequences.read more

A Fast Intra-Prediction Method in HEVC Using Rate-Distortion Estimation Based on Hadamard Transform
TL;DR: Among the many predefined modes, the intra‐prediction mode is chosen using the difference between the minimum and second minimum of the rate‐distortion cost estimation based on the Hadamard transform, which achieves a nearly similar coding performance to that of HEVC test model 2.1.

An SAD-Based Selective Bi-prediction Method for Fast Motion Estimation in High Efficiency Video Coding
TL;DR: A selective bi‐prediction method is proposed to reduce the encoding complexity of HEVC by evaluating the statistical property of the sum of absolute differences in the motion estimation process and determining whether bi-prediction is performed.

Speeding Up the Decisions of Quad-Tree Structures and Coding Modes for HEVC Coding Units
TL;DR: A fast algorithm for coding unit decision is proposed to reduce the burden of the encoding time in HEVC and exploits the temporal correlation in the neigh-boring frames of a video sequence to avoid the unnecessary examinations on CU quad-trees.

Analysis of Hierarchical B Pictures and MCTF
TL;DR: In this paper, an investigation of H.264/MPEG4-AVC conforming coding with hierarchical B pictures is presented, and simulation results turned out that in comparison to the widely used IBBP structure coding gains can be achieved at the expense of an increased coding delay.
