    Abstract: A method and circuit for deriving a set of multichannel audio signals from a conventional monaural or stereo audio signal uses an auxiliary multichannel spectral mapping data stream. Audio can be played back in stereo and multichannel formats from a conventional stereo signal on compact discs, FM radio, or other stereo or monaural delivery systems. The invention reduces the data rate needed for the transmission of multichannel digital audio.

    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. Temporary storage of the digital audio signal in the buffer memory accommodates breaks in the film, projector changeover and various time code validation schemes, and allows the digital data source in which the digital audio data is stored to be a relatively slow access high data reliability device such as a digital tape.

    Abstract: An improved method is disclosed for transferring motion pictures from film to videotape, with an improved video image quality for moving objects. In the preferred embodiment, the motion picture is filmed at twice the video frame rate, and alternating scanning fields from each pair of film frames are transferred to interleaved fields on a single video frame. The method substantially eliminates image jitter of moving objects, and is particularly adapted to a new 3-D television technique. Various alternate transfer systems are described, as well as a generalization of the invention to account for different film speeds or numbers of fields per frame.

    Abstract: An FM transmission system and method in which a gain control signal is generated and used to encode the audio signal in accordance with a predetermined compression curve. At the receiver the gain control signal is recovered and used to decode the audio signal, thereby providing a faithful reproduction of the original signal regardless of which compression curve is used. The compression curve can be tailored for optimum results for receivers with and without the decoding circuitry, depending upon the program material. The audio signal is delayed in the encoder while the gain control signal is generated, allowing the control signal to fully respond to changes in the audio signal without clipping the audio signal. The gain control signal is segregated from interfering with the remainder of the transmitted signal by restricting it to a low frequency bandwidth centered on the 38 KHz subcarrier for the L-R signal, and placing it in phase quadrature relation to the remainder of the transmitted signal. A number of different compression curve generators may be provided in the encoder to enable a selection among the different curves.

    Abstract: A method and apparatus is disclosed for the reproduction of a sound signal recorded on a variable density optical sound track negative, in which the amount of light transmitted through the sound track is related to its exposure by a predetermined relationship. Light transmitted through the sound track is transduced to an electrical signal having a magnitude which varies in accordance with the amount of transmitted light, and this signal is operated on by a function which is substantially equivalent to the inverse of the predetermined relationship to produce an output signal which directly corresponds to the exposure of the sound track. An adjustment mechanism is provided to eliminate distortion and to enable the production of an accurate output signal even when the relationship between the light transmission and exposure of the sound track is unknown. The prior art requirement of producing a print from the negative, with exacting and sometimes unknown characteristics, is eliminated by the use of a convenient electrical circuit.
