High efficiency video coding (HEVC) is the newest video coding standard that can support powerful video compression performance with increased picture resolution for ultrahigh definition (UHD). Compared to the previous standard, HEVC achieved a coding efficiency double with a tremendous increase in encoder computational complexity, making support of commercial applications for UHD video service difficult...
In this paper, a smoothed inter-layer residual prediction method is proposed for SHVC. The proposed method can reduce the prediction error presented in the enhancement layer by adding the residual signal of the reference layer to the motion-compensated prediction signal in the enhancement layer. The experimental results show that the proposed method can achieve BD-rate savings by refining the residual...
We present a novel video codec for supporting entertainment-quality. It has new coding tools that are intra prediction with offset, integer sine transform with adaptive quantization matrix selection, uni-directional intra prediction, and enhanced block-based adaptive loop filter. These tools are used adaptively in processing of transform, intra prediction, and loop filtering. In experiments, the proposed...
In UMA environments, because of the heterogeneous networks and terminals, flexible video adaptation, performed according to network conditions and terminal capabilities as well as user preferences, is required to maximize user experience and ensure quality of service (QoS). We propose an adaptation method of scalable video using MPEG-21 digital item adaptation (DIA) that provides systematic solutions...
