Slepian-Wolf video coding with resolution-progressive transmission

Abstract

In this paper, we propose a new Slepian-Wolf (SW) video coding that supports resolution-progressive transmission. It can realize low-delay low-resolution real time streaming as well as high lossless coding efficiency. Intra-frame video coding is performed as the base layer coder for down-sampled input video and a SW coder is used as the enhancement layer coder for lossless archiving. In order to improve SW lossless coding efficiency, we introduce inter-layer prediction between the base layer and the enhancement layer. It uses inter-layer prediction to increase the accuracy of Motion Estimation (ME). Simulations show that the proposed scheme gives higher coding performance better than the JPEG2000 lossless mode.
