Quantization control for improvement of image quality compatible with MPEG2

A new quantization control method for a moving picture coding system, based on MPEG 2 video syntax, is discussed. The quantization control method consists of MB (macro block) activity calculation and rate control. In considering of human visual characteristics and coding efficiency, the quantization...
