摘要： Digital cinema exhibition facilities make use of a show play list (SPL) specifying a time sequence of the events to occur during the presentation of digital cinema content. One or more cues in the show play list trigger certain activities, such as displacing the screen curtain and dimming the house lights. To achieve an aesthetic, showman-like presentation, the cues in the show play undergo re-cuing. For each cue, a determination is made automatically of the prefire interval, that is, the interval by which the cue should be advanced. The execution the cue to trigger a corresponding activity is advanced by the automatically determined pre-fire interval.

摘要： A digital sound signal reading means 20 is provided in association with a sound drum 13 on which an image film 1 delivered from a cinema film supply unit 50 circumferentially travels to carry out reading and reproduction of digital sound signals recorded in a digital sound signal recording portion 5 of the image film 1. An image film traveling adjustment unit 30 is disposed at least at the position of the preceding stage of the image film traveling path. The image film traveling adjustment unit 30 applies traveling load in dependency upon traveling state of the image film 1 to allow the image film 1 to travel up to the digital sound signal reading means 2 in a stable state thus to allow it to carry out reading and reproduction of digital sound signals.

摘要： A system for preventing improper tape feed in a cassette tape player uses pulse width measurements from the take-up reel output signal to sense normal or aberrant tape feeding conditions. The pulse width of the output signal is compared with a predetermined range of pulse widths associated with normal tape operation. The range is variable as a function of the rotational frequency of the take-up reel and is updated periodically to reflect changes in the diameter of the take-up reel as the tape plays. If the pulse width of the output signal falls outside of the predetermined range, it denotes an aberrant tape feeding condition.

摘要： A motion picture apparatus is provided which comprises a rotary disc shutter having a shutter sector and actuated by an electric drive device. A claw mechanism is controlled by the electric drive device and provides for transport of a film. An electromagnetic solenoid provides for stopping the film in position. A plunger for the solenoid is provided for disengaging the claw transport mechanism after a frame transport phase upon generation of an appropriate signal. A position signal generator provides a shutter position signal depending on the position of the shutter sector and a marking signal generator provides a signal depending on the detection of a marking placed on the film. The position signal generator is connected to a first input of an AND gate and the marking signal generator is connected to a second input of the AND gate. The output of the AND gate is connected to the solenoid.The apparatus and a corresponding method provide for stopping a film without interference in proper position.

摘要： A motion picture camera has a rotary shutter driven by a DC motor which is supplied from a battery. The camera also has an arrangement for making light markings for identification purposes on the film in the camera. This arrangement includes a light-emitting diode and a capacitor which is charged by the battery and discharges across the diode. The electrical circuitry is such that the capacitor is connected to the battery only when the motor is disconnected therefrom; inversely, when the motor is to be connected to the battery in order to operate the shutter (and also to advance the film), the capacitor is first disconnected from the battery before the motor is connected to it and then discharges across the diode. The circuit also suppresses afterglowing of the diode.

摘要： A motion picture film which includes a row of sprocket holes along one marginal edge portion and a longitudinally extending area carrying a photo-sensitive layer for photographing a selected scene, or series of scenes in a succession of stationary frames, the film being characterized in that one of its marginal edge portions carries a latent-image numerical identification of each of the successive frames in binary code form adjacent each said frame. A post-production film-making system is also described with means for transferring the binary numbers from the film to a magnetic medium and means for reading and visually displaying in arabic form the numbers on the film and the magnetic medium.

摘要： A sound motion picture camera capable of using a sound film is disclosed. The camera includes a film receiving chamber having an image recording location and a sound recording location, a first film feeding device for intermittently transporting a film loaded in the chamber from the image recording location toward the sound recording location, a second film feeding device for transporting the film transported by the first film feeding means further downstream from the sound recording location at a substantially constant speed, a switching device interposed between the first and second film feeding devices and a control device for controlling the operation of the film feeding devices. The switching device is so designed that ON-OFF of the switch is controlled by the movement of the film and that the switch produces pulse signals at an almost constant interval so long as the film transporting operations of the first and second film feeding devices are going well keeping a desired proper operating relation therebetween. But, whenever the operating relation of the two film feeding devices becomes disordered, the switch device continues putting out positive or negative signals. These signals are detected by the control device which terminates the film transporting operations of both the first and second film feeding devices when the ON or OFF signals continue coming out from the switching device for a longer time period than a predetermined time duration.

摘要： A device for sensing notches in an edge of a longitudinally transported film strip has a two-armed lever pivoted at a point to one side of the film path to deflect in the film plane. One arm carries at its end a spring biased roller which rotates freely against the moving unnotched film edge but which is biased into engagement with a notch to deflect the lever. The other lever arm is contacted by the actuating button of a microswitch the internal spring of which biases the lever to a quiescent position. A preselected deflection of the lever from this position actuates the microswitch to indicate the presence of a notch. Stops limit the deflection of the lever which is essentially normal to the direction of film movement, deflecting from a just obtuse to a just acute angle when entrained by a notch. The microswitch may be replaced by a photoelectric switching arrangement.
