  • System for recording a time code signal on motion picture film
    Patent number: 4504130
    Abstract: An apparatus and related method for recording a continuous digital time code on motion picture film as it is advanced intermittently by a motion picture camera. The apparatus controllably adjusts the time durations of the successive bits of the signal it records, to compensate for the variable velocity profile of the intermittently advancing film. As a result, the apparatus records the time code signal as a continuous signal with a uniform time base, even though the film is being moved in an intermittent and non-uniform fashion.
