图像局部更新在计算机远程控制技术中的应用

Application of Updating Partition Screen Image in the Technology of Computer Remote Control

屏幕图像的压缩与传输是远程控制技术中的重要技术之一.屏幕图像的数据量通常很大,全部传输的处理方法会降低远程控制的效率.提出了对屏幕划分不同的区域,对已经改变的区域的图像进行局部更新的方法,从而提高了远程控制的效率.

The compression and transmission of screen image is one of the most important technology. The amount of screen image data is very large, so the scheme of transmitting all the data will make remote control inefficient. A scheme of partitioning screen is applied and the screen image of changed regions are updated, which make remote control efficient.
