摘要
为了优化远程教育系统的性能并提高教学过程中的实时性，提出了一种基于三层架构的远程教育系统中的屏幕共享服务，介绍了屏幕组播和远程监控两大模块的设计方案。此方案在Visual C＋＋6.0环境下编写代码并调试通过，实现了屏幕共享服务中屏幕采集、图像压缩、屏幕传输以及鼠标，键盘响应四大功能，并在校园网上应用，运行状态良好。
In order to optimize the performance of the distance education and improve the real-time of the educating process, this article introduced a screen sharing service in distance education system based on 3-tired architecture. It mainly discussed the design of screen muhicast module and remote controlling module. This design has been coded and debugged under Visual C＋＋ 6.0 environment and realized four main functions： screen capture, image compression, screen transmission and response to remote mouse/keyboard. The whole system has been running well through campus network.
