International Classification:

G03B 3102
G06F 1100

US Classification:

352 27

Abstract:

A method and apparatus for reading digital audio signals photographically recorded on a medium (such as motion picture film). If the medium has multiple, spatially separated digital and analog audio soundtracks, a photosensitive detector array is employed for each of the digital audio soundtrack areas, and a separate analog soundtrack read head is employed. Preferably, digital error code is recorded in a digital soundtrack area of the medium (with digital audio bits), and error detection and correction are performed on the recorded digital audio bits read from the medium. Preferably, the apparatus includes switching circuitry for substituting a corresponding analog audio signal for one or more corrupted digital soundtrack channels, when such digital soundtrack channels have an error rate which exceeds a selected threshold. Also preferably, the invention reads recorded digital audio information by projecting a laser beam (having a near infrared wavelength) on a row of a digital soundtrack area of a motion picture film, to modulate the beam as it passes through the row. The radiation transmitted through each digital soundtrack bit area is projected onto a spot in the detector plane that is substantially larger than the dimension of each individual detector which receives the spot.

US Classification:

430140

Abstract:

A photosensitive medium, such as motion picture film, having digital data in multiple formats and analog audio signals photographically recorded thereon, and a system for photographically recording digital data (preferably including digital audio bits) in multiple formats and optionally also analog audio signals on a medium. Preferably, two digital soundtracks are recorded on the film, each in an array of bit areas arranged in row and column order, with the bit areas of one soundtrack between consecutive pairs of sprocket holes along one edge of the film, and the bit areas of the other soundtrack along the film edges outside the sprocket holes. Preferred embodiments of the invention include a camera assembly through which a motion picture film translates in real time. The camera assembly includes a first assembly for photographically recording digital data on the film in a first format by exposing the film to light of a first wavelength, a second assembly for photographically recording additional digital data on the film (in at least one different format than does the first assembly) by exposing the film to light of a second wavelength, and optionally also a third assembly for photographically recording analog audio signals on the film. Alternative embodiments include a first camera assembly for recording digital data on the film in a first format by exposing the film to light of a first wavelength as the film translates at a real time rate, and a second camera assembly for recording additional digital data on the film (in at least one different format than does the first assembly) by exposing the film to light of a second wavelength as the film translates at a less than real time rate.

International Classification:

US Classification:

352 27

Abstract:

A method and apparatus for photographically recording digital audio signals, and a medium having digital audio signals photographically recorded thereon. In a preferred embodiment, a motion picture film recorded in accordance with the invention has multiple digital audio soundtracks and an analog audio soundtrack photographically recorded thereon. Two or more channels of digital audio information can be recorded in each digital soundtrack, along with additional digital information for clocking, tracking, and error detection and correction. Each digital soundtrack is recorded in an array of bit areas arranged in row and column order. In a class of preferred embodiments, each row of digital audio bits is recorded simultaneously by exposing the film to radiation that has been modulated by a linear shutter array. The radiation transmitted by each shutter array is projected onto a row of spots. Each spot covers the full width of one of the bit areas in a row, but only part of the length of the bit area.

US Classification:

Abstract:

An add-on module for a contact printer used to manufacture a motion picture. The module enables the printing of a digital optical soundtrack on motion picture film from a sound negative using a standard contact printing process. The module includes spaced apart guide rollers and a main roller. Unexposed film is placed in contact between the main roller and the sound negative. The module further includes a fiber optic light source positioned adjacent to the sound negative for exposing the film and forming the digital soundtrack. The digital soundtrack is formed on a portion of the positive print which includes an area between each of the sprocket holes. In addition, the digital soundtrack extends from each sprocket hole to the edge of the positive print on both sides of the print.
