Patent ID: 8766994

Claim:
A method for reducing image latency in a video display system using a stroke video frame technique in which a video image is displayed for a stroke video frame period, the system comprising a display device and a plurality of raster memory buffers, each of which is adapted to be either in communication with a source for receiving image data when in a receiving condition or in communication with the display device when in a display condition, the method comprising the steps of: dividing the stroke video frame period into at least two raster memory time periods; providing the video display system, such that the number of raster memory buffers equals or exceeds the number of raster memory time periods per stroke video frame period; arranging the video display system such that only one of the raster memory buffers is in the display condition for a first raster memory time period and the remainder of the raster memory buffers are in the receiving condition; displaying on the display device the image data from the raster memory buffer in the display condition for a raster memory time period where the raster memory buffer in the display condition contains information for two separate video frames; and rotating the arrangement of the raster memory buffers at the end of the raster memory time period, so that the raster memory buffer in the display condition rotates into a receiving condition and one of the raster memory buffers in the receiving condition rotates into the display condition.
