| Number | Title | Issue Date |
| 4835607 | Method and apparatus for expanding compressed video data A processor which expands a compressed video signal is disclosed. The compressed video signal applied to the processor is generated by partitioning a video image into segments and then describing how each segment is filled by using a bilinear equation, th... | 05/30/1989 |
| 4821208 | Display processors accommodating the description of color pixels in variable-length codes A display processor, as for a small computer, processes pixel codes of various lengths. Three addressable color maps have their read addresses generated independently from portions of each pixel code. The portions of each pixel code used in generating eac... | 04/11/1989 |
| 4791594 | Random-access psuedo random number generator 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 cont... | 12/13/1988 |
| 4791580 | Display processor updating its color map memories from the serial output port of a video random-access memory 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 ... | 12/13/1988 |
| 4785349 | Digital video decompression system 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 codin... | 11/15/1988 |
| 4777481 | Display processor for image data with non-constant pixel size for chromatic values 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... | 10/11/1988 |
