On The Error Distribution And Scene Change For The Bit Rate Control Of MPEG

In this paper, an improved MpEG-based adaptive bit rate control algorithm which utilizes the predictive and delta modulation techniques in the regulation of quantization parameters is proposed. In addition, the influence of scene change is considered in order to avoid the picture &gmlationcaused by an inconeCt bit allocation after the scene change event. The algorithm has produced mote stable picture quality and a more accurate bit rate in themacroMocklayerthanMPEG.
