摘要
针对现有计算机屏幕图像传输技术使用网络带宽过大、占用系统资源过多、实时性差等问题,分析了影响计算机屏幕传输速度的几个因素,提出采用差异截图方式改进远程屏幕图像实时传输方法。通过对计算机屏幕相邻帧图像进行比较,仅对存在差异的部分进行截图和传输,减少网络数据传输量,实现屏幕图像快速传输。
To solve the problem of the over-sized band width, over-occupied system resources and the lack of real time in the present screen picture transmission technique, the paper has analyzed several factors that influence the speed of screen transmission, and put forward a means to improve the live transmission of telescreen image by picture difference capture. By comparing the difference between consecutive frames, only the variant part is captured and transmitted to decrease network data transmission and achieve speed transmission of screen picture.
