Abstract

Scalable video coding is important in a number of applications where video needs to be decoded and displayed at a variety of resolution scales. In this paper, we investigate the spatial-domain approach for spatial resolution scalability. We employ the framework proposed for the ongoing second phase of Moving Picture Experts Group (MPEG-2) standard to introduce a general coding structure and discuss key issues in progressive-to-interlace and interlace-to-interlace scalable coding. We discuss the technique of spatio-temporal weighted prediction and show detailed encoder and decoder structures employing this technique. In our simulations we focus on 2-layer progressive-to-interlace spatially scalable coding and compare its performance with the simulcast technique at different bit-rates. Next, we evaluate the performance of spatially scalable coding for different picture types. Finally, we examine the efficiency of a chosen set of weight codes in spatio-temporal weighted prediction and propose improvements.
