Abstract

The newest family of H.264 video coding standards (AVC, SVC, and MVC) have shown great rate distortion performance improvements compared to the MPEG-2/MPEG-4 standards. The improvements come from the use of multiple reference frames, multiple intra prediction modes, motion estimation with variable block sizes, quarter-pixel accuracy, integer cosine transform and Context-adaptive binary arithmetic coding (CABAC). However, these improvements impose a high computational cost, which makes the implementations of this family of standards challenging for real time applications. In this special issue, a variety of algorithmic and micro-architectural optimisations are proposed for reducing the computational cost while retaining the rate distortion performance of the standards at acceptable levels. The issue consists of nine papers and the remainder of this editorial presents a brief summary for each of them.
