  • Processing multiple regions on an image in a graphics display system
    Patent number: 8963934
    Abstract: There is described a method and circuit for independently processing a plurality of regions of an image to be displayed on a display device. The circuit comprises a plurality of transformation modules; a multiplexer having a plurality of inputs and an output for selectively transmitting one of the output values from one of the plurality of transformation modules, and a selector line; and a selection module operatively connected to the selector line of the multiplexer and configured to determine a position of the pixel in the image and identify a transformation module corresponding to a region with a highest priority level for a pixel position, and cause the multiplexer to output the output value from the identified transformation module as the post-transformation pixel for display on the display device.

  • Displaying multiple compressed video streams on display devices
    Patent number: 8189681
    Abstract: A method and display system for displaying compressed video streams from a plurality of video sources. The display system comprises an input module for decompressing a compressed video stream in an intermediate data format, an intermediate module for receiving the video stream in the intermediate data format incompatible with a display device, and an output module for converting the video stream in the intermediate format into a final data format to be displayed on the display device.
