Abstract
Common key frames are provided to a client during initialization to provide more efficient remoting of user interface graphical information. By storing the common key frames at the client, the common key frames may be loaded quicker and more efficiently at the client without having to resend graphical information for each common key frame each time a common key frame is used to provide a new frame. Differences between a selected common key frame and the new frame are encoded as delta commands. A payload containing a common key frame command, which identifies a common key frame at the client, and delta commands which encode differences between the selected common key frame and new frame is sent to the client. The client receives the payload, sets a cached common key frame as the current frame, applies the delta commands to the selected common key frame, and renders the new frame.
