Abstract :
Parallel video coding has emerged from the need to map video algorithms in many/multi-core architectures and achieve ever-growing performance goals in video-based applications. Several parallelization methods have been proposed around H.264 algorithm but it was only until the new HEVC video standard that two parallelization strategies-Tiles and Wave front Parallel Processing (WPP) became part of the specification. Effective selection and usage of Tiles or WPP is an open issue. In this paper we evaluate the performance of both strategies in terms of video decoding speed-up including their correlation with additional optimization possibilities like parallel filtering and low-level SIMD operations.
