  • Method and system for vertical filtering using window descriptors
    Patent number: 8942295
    Abstract: Herein described is a method and system of vertically filtering a graphics image such that an enhanced image is provided to a display. Filtering of the graphics image may be accomplished by using one or more window descriptors. The method may be implemented by computing a weighted average of one or more pixel intensities. The system may comprise a memory, a processor, and a graphics engine. The graphics engine may comprise a graphics blender. The graphics blender may comprise one or more multipliers and one or more adders. The processor may execute software resident in the memory, such that the one or more window descriptors may be used to compute the weighted average.

  • Low resolution graphics mode support using window descriptors
    Patent number: 8199154
    Abstract: Herein described is a method and system of displaying low resolution graphics onto a high resolution display. The low resolution graphics may be displayed using one or more displayable maps or surfaces, each of which is defined by way of one or more parameters. The display may comprise a monitor, television set, or set top box, capable of displaying at a particular resolution. In one or more representative embodiments, the various aspects of the invention permit scaling the low resolution graphics onto the high resolution display by way of using the one or more displayable maps or surfaces such that the graphics data is properly displayed on the higher resolution display.
