摘要

微软远程桌面协议(RDP)用于控制远程计算机的屏幕活动。RDP支持各种机制来减少通过低带宽网络连接传输的数据量,例如数据压缩、位图缓存等。我们利用这些特点开发了一个远程屏幕录制系统,该系统可以应用于计算机教学和商务演示。目前,有各种各样的屏幕记录工具可供选择。然而,这些基于视频的屏幕记录系统存在输出质量差和存储容量大的问题。相对而言,我们开发的远程屏幕录制回放系统输出质量优异,录制文件比压缩视频文件需要更小。

Remote Screen Recording and Playback
Microsoft Remote Desktop Protocol (RDP) is used to control the screen activities of a remote computer. The RDP supports various mechanisms to reduce the amount of data transmitted over a low-bandwidth network connection, such as data compression, caching of bitmaps, etc. We used all these features to develop a remote screen recording system, which can be applied to computer education and business presentation. Presently, a variety of screen recording tools are available. However, these video based screen recording systems have problems with poor output quality and large storage requirement. Comparatively speaking, the remote screen recording and playback system we developed produces excellent output quality and requires a smaller recorded file than the compressed video files.
