Abstract: A method and system for compressing bitmap data in a system for sharing an application running on a host computer with a remote computer, wherein the shared application's screen output is simultaneously displayed on both computers. Simultaneous display of screen output is achieved by efficiently transmitting display data between the host computer and the remote computer. When a 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, transmitted, then decompressed by the computer.

Abstract translation: 一种在系统中压缩位图数据的方法和系统，用于与远程计算机共享在主机上运行的应用，其中共享应用的屏幕输出同时显示在两台计算机上。 通过在主机和远程计算机之间高效地传输显示数据，实现屏幕输出的同时显示。 当主机用于显示文本的字体在远程计算机上不可用时，主机计算机发送用于显示的文本的位图表示，而不是文本本身。 位图表示由远程计算机缓存，使得相同的位图表示不需要从主机重复地发送到远程计算机。 位图表示在传输之前由主机压缩，发送，然后由计算机解压缩。
