视频编解码器中量化器的设计与实现，阐述了采用两个步骤设计9’ #: 量化器：首先利用缓冲器纯占有控

制算法来确定量化器的粗量化步长；然后利用视觉特性控制来确定量化器的精量化

步长。-Video codec in the quantizer design and implementation, described using a two-step design 9 ' #:　quantization: first, the use of buffer control algorithm to determine the pure possession of rough quantization quantization step　and control the use of visual features to determine the quantization fine quantization step.
