Abstract

In this paper, the frequency scanning and the Modified Universal Variable Length Coding (MUVLC) technique is examined as a means to improve the cell loss resilience of video codecs. An appropriate implementation of this technique for effective use in a pyramid layered coding scheme is described. Simulation results are presented which show the superior performance of this slice based coding technique in comparison to the conventional block scanning and Variable Length Coding (VLC) technique having similar coding efficiency.
