Japanese Patent JPS4851633
Kind Code:
A
Abstract:
A motion picture camera generates a synchronization signal related to the rate of film transport through the camera. The synchronization signal is translated to a higher frequency and mixed with an audio signal. The composite signal is recorded upon the tape of a monaural recorder. During playback, the synchronization signal is separated from the audio signal and translated down in frequency. The translated synchronization signal is compared with a similar signal generated by the projector and the resultant signal utilized to control the speed of the projector.
