    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: Message storage capacity is provided on memory modules, the number of modules being expandable to increase the capacity of the system. Each module has digital memory which is organized with a plurality of message units, each message unit including a number of successive memory bytes for storing respective messages. A desired message is accessed by stepping through the message units to the desired location having the start of the desired meassage, skipping the intervening bytes. The message is then read out at the system clock rate. The memory of each module is preferably addressed by a corresponding counter which has a lower order control input for counting up at one memory byte per count, and a higher order control input for counting up at an accelerated rate of one message unit per count. A microprocessor controller causes each of the memory modules to access the location of the desired message through a fast access line, and then causes the desired message to be read out from its particular module while readout from the other modules is inhibited.

    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 is also applicable to the direct transfer of computer generated artwork and the like directly to video storage, without an intermediate film stage; a pair of time-spaced line fields are generated and interleaved for each video frame. The method substantially eliminates image jitter and smearing 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: A method for creating a 3-D television effect is disclosed in which a scene is recorded with a relative lateral movement between the scene and the recording mechanism. The recording is played back and viewed through a pair of viewer glasses in which one of the lenses is darker and has a spectral transmission characterized by a reduced transmissivity at least one, and preferably all three, of the television's peak radiant energy wavebands. The lighter lens, on the other hand, has a spectral transmission characterized by a reduced transmissivity at wavelengths removed from the television energy peaks. The result is a substantially greater effective optical density differential between the two lenses when viewing television than in normal ambient light. This produces a very noticeable 3-D effect for television scenes with the proper movement, while avoiding the prior "dead eye" effect associated with too great a density differential in ordinary light. Further enhancement is achieved by providing the darker lens with a higher transmissivity in the blue and red regions than in the yellow or green regions.

    Abstract: Apparatus and an associated method are described for encoding an analog signal to a digital representation thereof and then decoding the same to reconstruct the original analog signal with reduced quantization noise and error. The analog signal is first adaptively pre-emphasized. A series of samples of the pre-emphasized signal are then obtained and encoded to create a series of digital representations which have a lower order resolution than the samples. The difference between each sample and its corresponding lower resolution digital representation is obtained and combined with the next sample. Decoding of the combined signals takes place in a complementary manner to create an approximate analog output signal, which is then de-emphasized in a manner complementary to the pre-emphasis to produce an analog output signal closely approximating the original analog signal. In a fully digital implementation the samples are converted to a digital format with a higher order resolution; the digital representations are obtained from the digitized samples, and the difference measurements are combined with the samples in their digital format. In a hybrid digital/analog implementation the difference is combined with the analog signal prior to sampling.

    Abstract: A method and apparatus for detecting crossmodulation distortion on an optical sound track by detecting variations in the light transmitted through a predetermined area on the sound track, the predetermined area being selected such that its transmittance varies substantially only with the amount of crossmodulation distortion on the sound track. The predetermined area preferably has a dimension along the sound track which is a whole number multiple of, and substantially greater than, the wavelength of a high frequency test signal. Light is also transmitted through a second predetermined area on the sound track which clips the high frequency test signal, thereby providing a low frequency phase reference for determining the relative exposure of the film. In an alternate embodiment, the predetermined areas are divided into primary and secondary areas, mutually spaced by a distance which is out-of-phase with respect to the wavelength of a low frequency test signal. Crossmodulation distortion information is obtained by comparing the light transmitted through both areas. Instead of single predetermined areas, multiple areas spaced by whole number multiples of the low frequency signal wavelength can be used to improve the resolution of the system's frequency response. A mask with defined apertures controls the light paths. Testing for crossmodulation distortion can be done by simply moving the film by hand a short distance through the test equipment. Because crossmodulation is continuously monitored, diagnostic testing is also possible.
