Abstract
Analog video signals representative of a video picture are generated by a video camera or the like, and the analog video signals are digitized. The digitized analog video signals are fed to a coincidence gating circuit, to which manually operable digitally generated signals are also fed. The analog video signals are mixed with the output signals from the coincidence gating circuit and are fed to a cathode ray tube for display.
