  • Patent number: 6262776
    Abstract: A system for playing video data ahead of corresponding audio data in order to help maintain synchronization between the audio data and the video data. Two software objects or filters are used to process the video data. An initial start time of the video data is determined and, if possible, the frame of video data is decoded or else it is selectively dropped in order to help maintain synchronization. An adaptive offset time is applied to the initial start time of a decoded frame of video data in order to produce an adjusted start time for the decoded frame. The offset time can be adapted to include a refresh offset related to sweep delays in computer monitors, a target offset which helps to build in a play-ahead margin for future late frames, and an earliness offset which is diminishing over time to help smooth transitions due to changing apparent video processing power. Additionally, the playing of video data can be slowed down in response to a low condition of the audio buffer.

  • Patent number: 6256058
    Abstract: In a computerized image processing system, a camera acquires a set of images of a scene while rotating the camera about an axis passing through an optical center of the camera. The images of the set overlap each other. An initial estimate of the focal length of the camera is made. The initial focal length can be any reasonable focal length. Using the initial estimate of the focal length, the set of images are composited in a memory to determine an estimated initial composited length. A next best estimate of the focal length is derived from the initial estimated composited length. The set of images are recomposed using the next best focal length estimate. This process is iterated until the absolute difference between the successive estimates of the focal length is less than a predetermined threshold to calibrate the camera.

  • Patent number: 6226054
    Abstract: A method for performing pulse width modulation (PWM) on a binary spatial light modulator using spatial-temporal multiplexing. A 10% light boost is achieved by eliminating deadtimes that are typically generated using the global-reset operation of a DMD when bit-planes having small on times are utilized. The number of bit-planes required is reduced by using a combination of binary and ternary bit-planes to achieve grayscale of a displayed digital image. By using a combination of spatial and temporal processing, digital pixel values can be displayed using a reduced number of bit-planes, without generating perceived artifacts such as pulsing due to pixels being turned on-off from frame to frame.

  • Patent number: 6222589
    Abstract: A convectional 2-1 interlaced (nominally 50 Hz field rate or nominally 60 Hz field rate) television signal is converted to a form suitable for display on a progressively-scanned variable-frame-rate high-resolution computer-type monitor. First, a succession of progressively-scanned video frames is derived from the interlaced television signal and each frame is repeated at least twice in succession When the interlaced television sign is derived from a motion picture source, the progressively scanned frames are derived by merging opposite polarity fields derived from tho same motion picture frame. For other sources, other interlace-to-progressive scan techniques, such as line duplication or line interpolation, are employed. The sequences of repeated progressively-scanned frames are written into a two frame memory at rate derived from the timing of the progressively-scanned video frames and are read out at a rate derived from the timing of the monitor's frame rate.

  • Patent number: 6198478
    Abstract: A CATV transmission center apparatus, a subscriber terminal device, a CATV distribution system, and a method of distributing a program, will solve the problems of the need to change transmission facilities for handling more channels, the costly CATV infrastructure per program, the expensive subscriber terminal devices, and the tedious and time-consuming process of selecting desired programs. When there is a request to view a program which is not being distributed from the subscriber terminal device to the CATV transmission center apparatus, an empty channel is searched for. If an empty channel is found, the requested program is distributed via the empty channel. All subscriber terminal devices are notified that the program which has started to be distributed is being distributed. The CATV transmission center apparatus distributes only those programs which are actually viewed by subscribers.
