A display order oriented scalable video decoder

Abstract

As network technologies advance, Scalable Video Coding (SVC) has become increasingly popular due to its universal multimedia access capability and competitive compression performance with the state-of-the-art single-layer video coding. However, it's decoding delay, memory bandwidth and storage requirement are much larger than those of single-layer video coding due to various scalabilities. In this paper, we propose a novel display order instead of direct bitstream order oriented decoding method for the SVC decoder to solve above implementation problems. The analysis for hardware-oriented algorithm shows that the proposed decoding order can reduce the decoding delay, memory bandwidth and storage requirement significantly while is still applicable to various scalable requirements.
