Video Coding Technologies for UHD Video

Technologies for Next - Generation Video Coding Standard

1. Trends of HEVC Standardization The target of HEVC standardization is to substantially surpass the compression efficiency of the existing MPEG-4 AVC/H.264 international standard,(1) which currently provides the highest compression performance. The expected complexity of HEVC must be an acceptable level for the hardware technology when supported products are put on the market. In the standardi...

HEVC Hardware Decoder Implementation for UHD Video Applications

In this paper, an efficient hardware architecture that exploits parallel processing for HEVC decoders is proposed by introducing (i) a Coding Tree Unit (CTU)-level pipelined architecture for single-core based processing; and (ii) a multi-core based parallel processing architecture for picture partition decoding with low latency while not requiring additional resources for in-loop filtering (ILF...

Video on Mobile CPU: UHD Video Parallel Decoding for Asymmetric Multicores

This paper proposes a novel High E ciency Video Coding (HEVC) Tile partitioning method for parallel processing by analyzing the computing ability of asymmetric multicores. The proposed method (i) analyzes the computing ability of asymmetric multicores and (ii) makes a regression model of computational complexity per video resolutions. Finally, the model (iii) determines the optimal HEVC Tile re...

Full Reference Video Quality Model for UHD HEVC Encoded Sequences

Despite its relative robustness, subjective video quality evaluation is a time-consuming and costly process. Alternatives are required therefore to simplify visual quality estimation, particularly in the case of new video formats. This paper presents an analysis of full reference quality metrics focused on Ultra High Definition sequences, encoded with H.265/High Efficiency Video Coding. After e...
