Abstract:
A video broadcast system for generating a plurality of program signals and broadcasting said program signals, said system comprising:a first program generator for generating a first program signal, said first program generator comprising:a first video data source for providing a first video signal;a first signal splitter coupled to receive said first video signal, said signal splitter generating a first video data stream and a second video data stream, said first video data stream comprising video data in excess of a threshold;means for temporally shifting said excess video data in said first video data stream relative to said second video data stream; andmeans for recombining said first video data stream with said second video data stream after said first video data stream has been temporally shifted relative to said second video data stream;a second program generator for generating a second program signal, said second program generator comprising:a second video data source for providing a second video signal;a second signal splitter coupled to receive said second video signal, said second signal splitter generating a third video data stream and a fourth video data stream, said third video data stream comprising video data in excess of a threshold;means for temporally shifting said excess video data in said third video data stream relative to said fourth video data stream; andmeans for recombining said third video data stream with said fourth video data stream after said third video data stream has been temporally shifted relative to said fourth video data stream;a multiplexer for combining said first and second program signals; andmeans for broadcasting said program signals to a plurality of remote locations.
