ABSTRACT:
A method and system sharing an application running on a host computer with a remote computer by simultaneously displaying the application's screen output on both computers. Simultaneous display of screen output is achieved by efficiently transmitting display data from the host computer to the remote computer. Data that will not result in a visible display on the remote computer is detected by the host computer and not transmitted, eliminating unnecessary transmission and processing of data by the remote computer. Pixel depth translation is done on the computer system capable of most accurately translating pixel depth. When the font used by the host computer for displaying text is not available on the remote computer, the host computer sends a bitmap representation of the text for display, rather than the text itself Bitmap representations are cached by the remote computer, so that the same bitmap representation need not be repeatedly transmitted from the host computer to the remote computer. Bitmap representations are compressed by the host computer prior to transmission.
