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...

Zusammenfassung:	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 control method performs a high quality compression of the digital video signal.< >
