Abstract:
1. A system comprising: a video input interface configured to receive video data having a pixel sequence from an external video source, the video input interface further configured to compress the video data using a compression algorithm based on the difference in color between two adjacent pixels in the pixel sequence, wherein the compression algorithm separately compresses each of a plurality of color values for each pixel with respect to each of three primary colors to generate compressed video data, wherein the video input interface is further configured to group consecutive pixels determined to be compressible based on the color difference into a fully compressed word; wherein the compression algorithm of the video input interface compresses two or more adjacent pixels, each of which is originally stored in a data word, into one fully compressed data word only when the difference between each pair of the two adjacent pixels does not exceed a predetermined threshold, and does not compress the two or more adjacent pixels when the difference between each pair of two adjacent pixels exceeds the predetermined threshold; and a video display controller configured to receive the compressed video data, the video display controller further configured to decode the compressed video data for transmission to an external video display.
