Abstract:

A method of refreshing a display, the method comprising: computing a frame indicator sequence comprising one or more frame indicators for each frame sample in a sequence of frame samples to be output to the display; loading each frame sample into an available video frame buffer of a plurality of rotatable video frame buffers of a video adapter; obtaining, by the video adapter from a queue containing the frame indicator sequence, a frame indicator associated with a current refresh period of the display; refreshing the display by delaying rotation of the plurality of rotatable video frame buffers and re-using a previously-displayed frame sample contained in a current video frame buffer, if the obtained frame indicator indicates no new frame for the current refresh period; and refreshing the display by rotating the plurality of rotatable video frame buffers to a next video frame buffer and using a frame sample that has not yet been displayed, if the obtained frame indicator indicates a new frame for the current refresh period.
