Abstract
A system for mixing and/or keying video signals includes a number of video signal processors each of which includes a charge-coupled device as a variable delay element to bring about phase coincidence among a plurality of video signals. The amplitude of the delayed video signal from the charge-coupled device is controlled, and the amplitude-controlled video signals are mixed.
