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:
This invention provides methods and apparatus for providing customized prior-to-answer and in-call media playback telephony services. The services allow for playback of customized media content to calling parties in the form of customized ringback tones, engaged tones, call holding, call transfer tones and other content such as pre-recorded announcements. The media content for playback is stored in equipment associated with subscribers and playback of the media content is originated from the subscriber equipment. The invention allows subscribers to give their telephony services a personal touch as they can choose different items of media content for playback to different calling parties. As the media content is stored on subscriber equipment local to subscribers, no additional network resources such as data storage and data processing facilities are required.
