Abstract
A color television receiver and sound motion picture projector, using a one-gun sequential phosphor stripe receiving tube for display, and a common audio output amplifier and speaker for sound presentation, in which a strip of sound motion picture film bearing a recorded sound track is moved at constant speed relative to a synchronization station, a video signal generating station and a sound station to produce a set of signals that may be selectively applied to the output video amplifier, the audio amplifier, and the horizontal and vertical deflection systems of a color television receiver by manually operable switching means for selectively connecting the system as a television receiver, or interrupting the signals normally derived from the tuner of the receiver and substituting mutually compatible, but differently timed, signals produced from the film.
