Abstract
Abstract A video conferencing system and method that uses a central multimedia bridge to combine multimedia signals from a plurality of conference participants into a single composite signal for each participant. The system gives each conference participant the ability to customize their individual display of other participants, including keying in and out selected portions of the display and overlapping displayed images, and the ability to identify individual images in a composed video stream by click and drag operations or the like. The system uses a chain of video composing modules that can be extended as necessary to combine video signal streams from any number of conference participants in real time. Multimedia association software is provided for associating different media types to enhance display and manipulation capabilities for multimedia uses. The system also allows each user to dynamically change who can receive the information they provide to the conference.
