Abstract

A video signal compositing system uses advanced communication techniques to make compositing with virtual studio, blue screen, multi-color compositing, dynamic blue screen, add insertion, synthetic transfiguration, or panoramic displays more economical. A data communication system comprises a number of shared communications channels for transmitting data streams in a bi-directional manner. Multiple interface subsystems are coupled to the communications channels. The interface subsystems have a time slot controller that allocates time slots between the communication channels. A router is used in conjunction with the interface subsystems to define the time slots in which data on the shared communications channels are valid. Processing elements connected via the interface subsystem allow reconfiguration, via the shared communications channels, of processing operations performed. Shared communications channels solve problems in video timing and routing of video signals, including but limited to video compositing and spatial positioning. Multiple mask, dynamic tracking, 3-D depth imaging, image processing and stereoscopic imaging enhance image compositing on systems ranging from NTSC video, to HDTV, to panoramic display systems.
