  • Patent number: 8123358
    Abstract: Watermarking of a motion picture release print occurs by providing on at least one soundtrack at least one tone of a particular frequency on at least one location unique to the release print. Typically, placement of the particular frequency tone occurs on location(s) where the tone will have minimal impact on the existing soundtrack audio. A record of location(s) at which the particular frequency tone appears on the release print is maintained to facilitate comparison with the tones detected in audio visual work to determine whether the audio of an illegal media was recorded from that release print.

  • Publication number: 20110170069
    Abstract: A method and apparatus are described for monitoring frame alignment status and correcting misalignment for film in a stereoscopic 3D projection system, in which gap indicia are provided onto the film in a gap between images, whether the images belong to the same frame or different adjacent frames. Thus, gap indicia are positioned in at least one of an interframe gap and an intraframe gap of the stereoscopic film. During projection of the film, presence or absence of the gap indicia is used to determine a frame alignment status. Frame misalignment is then easily diagnosed and corrected. Characteristics of the gap indicia are modified for improving frame alignment diagnosis.

    Abstract: A motion picture code evaluator evaluates a transmitted motion picture based on losses caused by a transmission means. The evaluator includes means for testing the frame header of the motion picture code and determining the presence/absence of an error in the frame header to calculate the frame loss ratio per predetermined time. The evaluator further includes means for extracting a motion picture coding parameter contained in the frame header and detecting a variation in the motion picture coding parameter in the predetermined time, and means for summing the motion picture coding parameter and the motion picture coding parameter weighted by the variation in a motion picture coding parameter in the predetermined time to calculate an ideal motion picture information amount in a predetermined time. The motion picture code evaluator thereby obtains an actual motion picture information amount by multiplying the ideal motion picture information amount by 1-frame loss ratio.

  • 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.

    Abstract: A method and apparatus for controlling the positioning of a filmstrip in a film scanning gate using signal states derived from a pair of spaced film sprocket holes or perforation ("perf") sensors on either side of the film scanning gate in conjunction with line scan counts and filmstrip drive, stepper motor half-step counts. The filmstrip is advanced by the stepper motor in a pre-scan operation through the film scanning gate for line scanning the image frames at a low resolution and advanced in the reverse direction back into the film scanning gate for high resolution scanning in a main-scan operation. A line scan array of line scan counts and half-step counts as well as first and second perf arrays of half-step counts and perf sensor states are generated in the pre-scan operation. Image frame borders are located in the pre-scan operation as border line scan counts and correlated in the line scan array to the half step counts to go to in the main-scan.

  • 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.

    Abstract: A digital cue system for use with a motion picture projector permits activation of control functions in time synchronization with the passage through the projector of indicia or cues attached to the motion picture film. Each cue comprises one or more cue appliques arranged to form a digital code pattern which is detected to activate a control function associated therewith. In an exemplary embodiment, the cue appliques are metallic foils adhesively attached to the motion picture film. Passage of these appliques through the motion picture projector is detected by one or more non-contacting proximity detectors which generate signals indicative of the digital code patterns. Digital circuitry processes the signals output from the proximity detectors to determine the digital code corresponding to each pattern and a specific control function associated with that digital code is then activated.

  • Patent number: 3967887
    Abstract: A pair of signals optically different in consistency is placed on an image information recording film to be projected. A projector is provided with at least a pair of light detection elements in a position where signals may be detected. The difference between outputs from the elements is utilized as a detection signal. The above-described signals are detected by way of an ordinary speed of the film so as to automatically switch the projection mode thereof to other projection modes, such as a still projection mode, a slow motion projection mode, a fading projection mode, and still projection mode for the search and after the search. For this purpose there are provided with a control circuit for processing the output of the detection element and a drive mechanism for providing the respective projection mode in response to the output signal from the control circuit.
