ABSTRACT:
Apparatus for projecting a motion picture on a color television receiver screen with accompanying sound using the audio output apparatus of the television receiver, in which a linear scanning array including a slit source of light is used to develop three color video signals from a motion picture film, and a sound transducer is provided to reproduce a recorded sound signal accompanying the picture sequence. Synchronization signals are developed by a photoelectric pick-up which detects the location of sprocket holes in the film. Switching means are provided to substitute the signals produced by the film transducers for the corresponding signals formed in the television receiver from broadcast signals. The substitute signals are applied to the color amplifiers, to the vertical and horizontal deflection circuits, and to the audio output amplifier of the television receiver. The apparatus is operable to selectively produce either a conventional television program, or a sound motion picture.
