Abstract: Automatic detection of errors among different formatted sound tracks of the same language on a motion picture film stock can be achieved by first acquiring successive audio segments from each of the sound tracks. During a time window of prescribed duration, the audio of each different formatted track undergoes analysis to yield a numeric value. The successive analysis of the audio continues until no further audio exists for analysis. The resultant collection of numeric values undergoes formatting into a numeric file for comparison against a reference file representing audio obtained from a particular source, such as originally recorded material, a sound print, or a duplicated copy of a sound film. If the difference between a formatted numerical file and the reference file exceeds a threshold value, then an error exists in that formatted sound track, and an operator can take appropriate action.

Abstract: In a system and method for dynamically synchronizing a digital soundtrack with a moving picture in motion picture media, the system includes a device for presenting the motion picture media, wherein the motion picture media further includes an analog soundtrack. The digital soundtrack further includes a variable delay to compensate for the distance between a frame in the moving picture and a portion of the digital soundtrack corresponding thereto. A synchronizing device is correlated to a digital soundtrack pickup and an analog soundtrack picture in a feedback loop. A processor in the synchronizing device is adapted to process the digital soundtrack and the analog soundtrack to generate a control signal based on the difference between the location of a transient reference in the analog soundtrack and the same transient in the digital soundtrack, and to use the control system to adjust the variable delay in the digital soundtrack for synchronization thereof.

Abstract: A microfilm searching and reading device for selectively taking out a cartridge containing a target image from one or more microfilm cartridge stacks. The device comprises a framework defining at least one storing space extending substantially vertically for storing a stack of cartridges in a manner such that the cartridges are stacked one above another, a scanner for receiving a selected microfilm cartridge and having an image reader and an actuator for winding and rewinding the microfilm, a carrier for taking out the selected cartridge and for guiding the same to the scanner, and a restoring mechanism for putting the selected cartridge, after the target image has been read by the microfilm reader, in the lowermost or uppermost position of the storing space. The device further comprises a memory for storing the location of the restored cartridge, and a controller for controlling the carrier, the scanner and the restoring mechanism.

Abstract: A reproducing apparatus for automatically selecting and reproducing a recording medium comprises a reproducing device fixed at a predetermined position, for reproducing a recording medium loaded therein, a recording medium storing part arranged fixedly along a circular arc passing through the reproducing device, for storing a plurality of the recording mediums in a radial arrangement within a plurality of recording medium storing chambers each having an address assigned thereto, a designating circuit for designating an address corresponding to one storing chamber from among the plurality of storing chambers, and a recording medium holding and carrying mechanism constituted by an arm structure which is axially supported at a position corresponding to a center of the circular arc.

Abstract: A film projection system includes a collection of cartridges each containing a film program. The cartridges are stored in a storage magazine. A selector system permits a particular film program, which may be identified by a code, to be chosen and displaces the storage magazine so that the cartridge containing the selected film program is positioned at a transfer point in which it is adjacent a transfer mechanism. A transfer mechanism is adapted to remove the cartridge from the storage magazine and position the cartridge in a film reproduction unit. Upon positioning of the cartridge within the film reproduction unit, the film will be displaced within the cartridge and will be reproduced by the unit. Upon completion of the film program, the transfer mechanism removes the cartridge from the film reproduction unit and returns the cartridge to the storage magazine.
