摘要： Shaped glasses have curved surface lenses and spectrally complementary filters disposed on the curved surface lenses configured to compensate for wavelength shifts occurring due to viewing angles and other sources. The spectrally complementary filters include guard bands to prevent crosstalk between spectrally complementary portions of a 3D image viewed through the shaped glasses. In one embodiment, the spectrally complementary filters are disposed on the curved lenses with increasing layer thickness towards edges of the lenses. The projected complementary images may also be pre-shifted to compensate for subsequent wavelength shifts occurring while viewing the images.

摘要： Spectral separation filters for channels of a 3D image projection incorporate passbands of primary colors. In at least one of the filters, passbands are present in more than 3 primary colors. A set of two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional primary passbands of the first filter allow for an increased color space in projections through the filters compared to filters only having red, green, and blue primaries. The added flexibility of the increased color space is utilized to more closely match a color space and white point of a projector in which the filters are used.

摘要： A playback system in a digital cinema network synchronizes the presentation of visual and aural content by deriving timing information for packets of information that are conveyed in video and audio data streams, examining the timing information to determine if any misalignment between the two data streams is likely to be perceptible and, if the misalignment is deemed to be perceptible, introducing delays into one or both data streams to correct the misalignment. If the audio data stream precedes the video data stream, the audio data stream is delayed by an integer number of audio sample periods. If the video data stream precedes the audio data stream, the video data stream is delayed by an integer number of video frames and the audio data stream is delayed by an integer number of audio sample periods.

摘要： A storage medium carries physically distinct blocks of symbols representing digital information. The symbols are arranged in the blocks such that the digital information represented by the symbols can be determined from only the two-dimensional position of the symbols relative to one another and any other differentiable characteristic intrinsic to the symbols. A method and apparatus recovers the symbols using oversampling in two dimensions and derives the information represented by the symbols. Blocks having two or more two-dimensional alignment patterns with good auto-correlation properties are used in some embodiments to facilitate recovery of the digital information. In one embodiment, motion picture film carries a conventional analog soundtrack and a digital soundtrack for a plurality of channels; the digital soundtrack is represented by symbols carried on the film in the areas between sprocket hole perforations.
