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.
