Pixel interpolation circuitry as for a video signal processor |
March 28, 1989 |
| A processor for expanding a compressed video signal includes a pixel interpolator which interpolates between input pixel values in two dimensions. This interpolator calculates and stores intermediate pixel values which are interpolated in the vertical direction. A pair of these inter |

Random-access psuedo random number generator |
December 13, 1988 |
| A system for generating a series of psuedo random numbers so that numbers in the sequence may be randomly accessed. The system includes apparatus for scrambling the bits of a plurality of seed numbers. The pattern of bit scrambling is governed by the control number. The plurality of scra |

Display processor updating its color map memories from the serial output port of a video random- |
December 13, 1988 |
| A display processor for a computer with graphics capability includes color map memories addressed by portions of pixel codes during display line trace intervals. The read-outs from these color map memories provide the primary color component signals from which the drive signals for the |

Digital video decompression system |
November 15, 1988 |
| A full motion color digital video signal is compressed, formatted for transmission, recorded on compact disc media and decoded at conventional video frame rates. During compression, regions of a frame are individually analyzed to select optimum fill coding methods specific to each region |

Interpolator for compressed video data |
November 8, 1988 |
| A simplified-in-structure vertical interpolator for compressed video data down-loaded from image memory to an odd-line line storage memory and an even-line line storage memory is followed in cascade by a horizontal interpolator. The horizontal interpolator calculates the difference b |

Image storage using separately scanned luminance-detail and narrowband color-component variables |
October 18, 1988 |
| Computer main memory is used for storing relatively densely sampled luminance detail information concerning a television display and for storing relatively sparsely sampled narrowband color-component information concerning the same television display. The relatively densely sampled l |

Display processor for image data with non-constant pixel size for chromatic values |
October 11, 1988 |
| The invention is embodied in a system comprising image memory and a display processor that automatically processes video data which alternate between having chrominance pixels of greater area than luminance pixels and having chrominance pixels of the same area as luminance pixels. Subsam |
