图像压缩存贮系统的设计与实现

The System Design and Realization Of Digital Memory for Picture Pressure

论述数字图像的压缩与存贮原理，研究三画面同屏显示器中数字存贮系统的设计和实现方法。采用双场制单场型存贮方式，解决了因主子视频不同步、读写速率不一样而引起的读写不匹配等影响图像质量以及对器件的高速要求等问题．

Based on the theory of DTV, the Preciple of Digital Video memory and pictUre pvessure in size is introduced. The system design of Digital memory for multi-picture display and its Simplemention are dicussed in defail. Compared with other techniques, our technique that two groups of REM work in double shifts of 2 fields avoides some problems caused by the video error between big picture and small picture and the different rates for reading and writing, and the high speed for working is not need for.
