Mathematical analysis of MPEG compression capability and its application to rate control

Abstract

This paper presents mathematical frameworks of temporal predictive processing in the MPEG video compression standard. The coding gain is derived based on traditional prediction theories. The optimum ordering of three different picture types (I,P,B-pictures) is clarified according to the image source characteristics. A novel framework of the target bit assignment is presented with some experimental backgrounds. The solution consists of simple formulae, but provides drastic SNR gains to the conventional TM5 algorithm.
