  • Patent number: 5798818
    Abstract: A theater sound processing system that provides preset configurations including parameters that can be modified by a user. Other setup parameters are modifiable by the manufacturer or a third party such as a sound technician who provides such parameters at installation time. The parameters allow control of equalization settings, gain, noise reduction processing, surround sound processing, and other audio characteristics. The designation of user modifiable parameters and non-user modifiable parameters insures that the user is given safe control over necessary parts of the system. User-modifiable parameters are changed via a user interface. Other parameters can be transferred to the sound processing system via a portable computer or by communications link. In a digital sound processing embodiment of the invention the entire sound processing ability of the system can be updated by downloading new signal processing software.

  • Patent number: 5751398
    Abstract: A digital time code is printed in an area of a motion picture film, between the normal analog optical sound track and the picture frames, that is exposed along with the sound track when a print is made. This area is partially redeveloped, and normally reserved to isolate the analog sound track from the picture frames. Digital audio for the motion picture is stored in a large capacity high integrity archival digital storage system. The time codes corresponding to known locations on the film are read as the film is played, and in an anticipatory pass the digital audio signals for these frames are transferred to a fast access data storage buffer which temporarily stores the data before it is converted to analog format for theater play. The time code is read with light that is absorbed by the film dyes produced when the film is developed.

  • Patent number: 5450146
    Abstract: Dynamic range and passband problems in cinema sound transmission are solved by using a laser disk (9) read by a laser disk player (10, 11, 12) synchronized (14) with the original sound track of the film. Problems relating to splices in the film are solved by reading the sound in advance, in storing it in a memory (13), in reading it back subsequently from the memory, and, where necessary, in causing the memory read back system to jump (24) in order to avoid reproducing sound that corresponds to images that have been removed from the film.

  • Patent number: 5386255
    Abstract: A digital sound system for motion picture films employs a digital time code on the film to trigger the transfer of sound data from a digital audio store to a FIFO memory. The digital audio data is read out from the FIFO memory and played back in the theater at a constant rate, with any jumps in the digital time code handled by making a corresponding jump within the digital audio store but not in the FIFO memory. Readout from the FIFO memory and clocking of the digital-to-analog converters (DACs) used for theater playback is synchronized to the AC mains that powers the theater projector, and thus allows for an uninterrupted audio playback even if time code entries on the film are obliterated. The FIFO memory need only have enough capacity to accommodate the maximum audio store access time, and can be quite small.

  • Patent number: 4220403
    Abstract: Two or more motor driven systems are maintained in synchronism by a recorded wave of sine form on a tape driven by one of said systems, a signal derived from said sine wave being used to drive a stepper motor or stepper motors included in the other system or systems. The invention is particularly applicable to the synchronization of a film passing through a camera or projector with a sound track recorded on a magnetic tape, or of a number of films passing through a plurality of projectors or cameras. By converting the sine wave to pulses and maintaining a count of the pulses, (a) derived from the control signal and (b) supplied to the stepper motor, synchronism is maintained despite inertia effects during repeated starting, stopping and reversal of the drive.

    Abstract: The sound support comprises an address track with coded words dividing the sound support into consecutive sections, each associated with a particular address. The positioning of the sound support is controlled in such a manner as to advance a section of the sound support bearing a predetermined address, to the level of a reading head. The video support comprises images, each associated with a particular address, and its positioning is controlled so as to advance in front of a projection gate an image having a predetermined address. The simultaneous running of the sound and video supports are then controlled, the speed of image projection being able to vary and being controlled according to pre-recorded instructions on a control data support, the access to which is neither related to the advance motion of the sound support nor to the image support.

    Abstract: The present invention relates to a synchronization system of a cine-projector with a sound tape reproducer. It is characterized in that the phase of a signal corresponding to the film feeding speed of the film projector and that of a signal corresponding to the standard speed coming from the sound tape reproducer are compared with each other so as to control the film feeding speed of the cine-projector by means of the comparison output corresponding to the phase difference. In order to accomplish this, between the driving source for driving the internal mechanism of the cine-projector and the driving member for the internal mechanism, a transmission speed varying mechanism is provided in such a manner that the transmission speed varying mechanism is controlled by means of the film speed control driving source to be driven by the comparison output so as to maintain the synchronized state.

  • Patent number: 4050794
    Abstract: A system for synchronizing projection of a movie film with playback of a sound recording made simultaneously with filming of the movie by simple and economical adapter means compatible with existing camera, projector and sound equipment without substantial modification. The invention utilizes "home movie" type camera and projector equipment, with a tape recorder-playback unit as the sound system. The camera is powered from a power supply having a switch operated by the "play" button of the tape recorder, thereby starting and stopping operation of the camera and tape unit simultaneously during filming and recording. The tape drive motor is powered from a selectively controllable voltage supply, and is not connected to the supply through the normal electrical system of the tape unit, as is conventional.

  • Patent number: 3999842
    Abstract: A method and apparatus for the resynchronization of the transport of movie film (image carrier) with the movement of another information-carrying medium such as sound tape film. Speed control and synchronization signals are produced by means of sensing the sound tape movement which provides control synchronization signal, monitoring the image frames for each sequence on the movie film by means of a counter, and comparing in a coincidence circuit the image frame count signal with the signal from the sound tape. Desynchronization of the movie film and tape is indicated by the absence of a predetermined relationship between the number of image frames in a given sequence and the signal from the sound tape, whereupon the coincidence circuit energizes an appropriate control means via a switching mechanism, such as a gate circuit, which produces a resynchronization of the film and the sound tape.

    Abstract: An audio visual reproduction apparatus utilizing an improved tape and film cartridge which is completely enclosed to be tamper-proof and to be used by inexperienced personnel. The cartridge includes transparent apertures therein for projecting light therethrough to view slide films on an endless disc within the cartridge. A dual track magnetic tape on an endless spool provides audio messages corresponding to the slides to be viewed and control signals for switching the slides to correspond with messages. The reproduction apparatus includes a single drive unit which drives the endless tape and film disc through a slip friction type drive. A cooperating brake insures that the film will be held stationary as the message is being played and allows for change in film through the tape drive upon the presence of a control signal to indicate requirement for switching. The tape, drive and brake are accessable through an aperture in the case covered by a removable shutter.
