VIDEO GENERATOR CIRCUIT FOR A DYNAMIC DIGITAL TELEVISION DISPLAY ABSTRACT OF THE DISCLOSURE: A video generator is disclosed for use in a digital television display system, for converting randomly occurring data signals representing graphical patterns into a time- sequential video signal for use with a sequentially line scan- ned display device. The circuit is comprised of a threaded buffer connected to receive the data signals and adapted to sort the data signals into groups ordered by extremal scan line positions for the pattern represented. An intermediate buffer has a first input connected to the output of the threaded refresh buffer for storing the ordered data signals once during each display field before the display of the pattern represented and outputting the ordered data signals in synchronism with the line scans of the display. A graph- ical pattern generator is connected to the output of the intermediate buffer for decoding the ordered data signals outputted therefrom and generating on a first output line components of the pattern represented which lie along the display line to be scanned. A partial raster assembly storage is connected to the first output line from the graphical pattern generator, to store the components of the pattern represented which lie along the display line to be scanned. The graphical pattern generator modifies the decoded ordered data signals to identify the horizontal, coordinate for the intersection of the pattern represented with the next display line to be scanned, and outputs the modified data signal over a second output line to a second input line for storage in the intermediate buffer. -1-
