    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 filter wheel having spirally shaped left and right channel 3D filters. The 3D filters are, for example, spectral separation filters. The filter is mounted, for example, close to an integrating rod output of a projector. The left and right channel filtered light scrolls across a modulation device which is energized with correspondingly scrolling left and right image data. In one embodiment, the integrating rod comprises mirrored surfaces to facilitate recycling of light reflected off the filter wheel. The filter wheel may be placed in a single or dual projector configuration. In one embodiment, the filters are fixed at the end of an integrating rod using “re-cycled” light to illuminate different channels of a projection system.

    摘要： A dual projection system utilizes a first projector and a second projector to project alternating left and right channel images of a 3D display. The projectors are inversely synchronized such that while the first projector projects a right channel image the other projector projects a left channel image. A projection filter in each projector has left channel properties when the image being projected is a left channel image and right channel properties when the image being projected is a right channel image. The images projected from each projector alternate between left and right channel images approximately once per frame.
