Program schedule information recorded on film is converted into video signals by two video record players for transmission with audio signals through a selected channel to cable television subscribers. The film is incrementally advanced in reverse directions for alternate display of different information recorded on separate frames of the film under control of a sequence controller operating through relays to effect synchronized operation of the video and audio tape players.
