ABSTRACT:
A system for processing video signals to compensate for distance-induced video signal delays includes a camera controller and distant camera are arranged so that the camera controller generates and sends a synchronization signal to the camera, which upon receiving it generates and sends back to the camera controller a reference signal starting at a fixed time following camera receipt of the synchronization signal, and further arranged so that the reference signal upon receipt by the camera controller is compared by the reference pulse comparator to determine if it is late, early, or at an acceptable time, upon which determination a phase adjustment signal is generated and sent by the camera controller to the camera second timing generator phase offset adjustment section to adjust appropriately the timing of the insertion of a video signal onto the transmission line by the camera.
