Abstract:
A system which utilizes the processing capabilities of the graphics processing unit (GPU) in the graphics controller. Each frame of each video stream is decoded and converted to RGB values. The R and B values are resampled as appropriate using the GPU to provide values corresponding to the proper, slightly displaced locations on the display device. The resampled values for R and B and the original G values are provided to the frame buffer for final display. Each of these operations is done in real time for each frame of the video. Because each frame has had the color values resampled to provide a more appropriate value for the actual subpixel location the final displayed image more accurately reproduces the original color image.
