传统的屏幕传输采用的是这样的方法: 抓取屏幕--à传输--à显示图像,此为完成传输一幅的过程.不断重复此过程即可实现屏幕监控.但是这种方法因为图像数据容量大,而网络实际信道容量是有限的,所以效果很不理想,具体表现就是每幅图像之间间隔时间长.后来发展到抓取屏幕-à压缩数据-à传输-à解压缩-à显示图像.这样做速度的确有所提高.但是在INTENET上面效果仍然不好-Traditional transmission screen is used in this way: capture screen- à transmission- à display images, this piece for the completion of transfer process. This process can be repeated to monitor the achievement of the screen. However, this approach because the image data large capacity, and network the actual channel capacity is limited, so the effect is not ideal, is a concrete manifestation of spacing between each image a long time. subsequently developed to capture screen-à compression data-à transmission-à-à extract showed image. do indeed increase the speed. However, the effect is still not above intenet
