Abstract
Abstract Electronic system for producing a motion picture record containing two adjacent successions of picture frames separated by an intermediate strip containing synchronizing or reference information to be used by scanning apparatus during reproduciotn. The synchronizing information comprises a narrow window-type mark disposed in the intermediate strip in a precise predetermined location with respect to the frames, and reference information, which can also appear in a margin adjacent the frames, may comprise alternating relatively opaque and transparent portions. Additionally, the intermediate strip or margin of the record adjacent the frames of one of the successions contains a record of reference carrier waveform in the event that those frames carry a representation of color information in the form of modulation of a carrier. The system includes means for generating a signal at a predetermined time following the initiation of each vertical scanning sequence of the video source and a second signal in predetermined time relation to the horizontal scanning rate of the video source. Upon time coincidence of the generated signals, an output signal is mixed with the video signal and fed to the modulating input of a recording beam used in making the record. This results in recorded synchronizing or reference indicia in the intermediate strip or margin of the record medium.
