Abstract

Fine Granular Scalable (FGS) video coding is a key technology in MPEG-4 streaming video profile. With the Internet developing rapidly, it comes into being and adapts magnificently to Internet´s highly heterogeneity, providing with favorable robustness. However, FGS coding efficiency is low, which brings some Improving Algorithms of FGS. Progressive Fine Granular Scalable (PFGS) Coding is the significant improved algorithm of Fine Granular Scalable (FGS) video coding in MPEG-4. Although the coding efficiency of PFGS is improved, the memory requirement and computational complexity of this algorithm increase accordingly. Base on this fact, the thesis provides a improved PFGS coding scheme. The experiment result shows that the improved PFGS code efficiency nears that of PFGS, also it reduces memory and computation complexity and gives PFGS more practical value.
