ABSTRACT:
A flexible multipoint composition and bridging system is provided for video signal composition and bridging of a plurality of geographically dispersed locations. The system includes a centrally located bridging unit that receives video, audio and data signal substreams from each of the remote locations. Based on the data substreams from each location, the bridging unit resizes, cuts and pastes the various images into separate video montage images for display at each of the locations. The system enables users to optionally display video images or signals from one or more of the other locations within separate display windows at their respective terminals. The display windows can be zoomed, panned, scaled, translated, and partially or wholly occluded depending on a user's preferences or needs. The video images may be composed in signal space or entirely in transform space. Further, the flexible multipoint bridging system may be used for various applications, including video conferencing and broadcasting.
