Abstract: An automated security surveillance system determines a location of a possible disturbance and adjusts its cameras to record video footage of the disturbance. In one embodiment, a disturbance can be determined by recording audio of the nearby area. A system, coupled to a camera, may include an arrangement of four audio sensors recording audio of the nearby area to produce independent outputs. The system further may include a processing module configured to determine an angle and distance of an audio source relative to a location of the arrangement of the four audio sensors. The system can then adjust the camera by rotation along an azimuth or elevation angle and adjusting the zoom level to record video of the audio source. Through use of the system, a surveillance system can present an image of a source of possible disturbance to an operator more rapidly and precisely than through manual techniques.

The film also carries two separate sets of sound tracks, each corresponding to separate one of the first and second sequences of successive images for separate playback.

Abstract: For a reproduction of optical sound information in a double variable-area track (DZ) an optoelectronic converter device scans the optical sound track of a film. The converter device generates a digital image signal for buffer storage in the memory of a program-controlled data processing device. The data processing device derives the profile of the two edges of the double variable-area track from data values of the buffer-stored image signal. Audio data for a sound reproduction are generated using data about the edge profile determined.

Abstract: A system and method is provided for encoding an identifiable code into the audio content of a motion picture.

Abstract: A system and method for registering the frames of film with respect to an aperture in a motion picture projector. A registration reference mark is applied to each frame corresponding to the location of the frame on the film. When the film is intermittently stopped in the projector's film gate, the registration reference mark is read to determine the location of that frame relative to the immediately preceding frame. If the frame in the gate is misregistered, the gate is moved to correctly register the frame prior to projection. By properly registering the frames, the “jitter” and “weave” associated with conventional projectors is eliminated and resolution of the projected film image is enhanced.

The format of the media carrying the digital soundtracks also is unaltered. The “discreteness” of the digital soundtrack system is not audibly diminished by employing matrix technology to surround sound channels, particularly if active matrix decoding is employed.
