A Real-time Variable Algorithm For Bit Rate MPEG2 Video Coding Digital Storage Media

Abstract

In this paper, we propose a new real-time variable bit rate (VBR) MPEG2 video coding algorithm. In this algorithm, we define a bit allocation function that is the relationship between number of generated bits and quantizer scale. And the quantizer scale of the next picture is decided to satisfy the bit allocation function. We evaluate the proposed method with computer simulation and MPEG2 real-time encoder. I
