Abstract

Embodiments of the present invention provide an efficient and cost-effective implementation of a method and system for increasing the frame-display rate of a video display device. Video data is often input to a video-display device in a compressed form that includes encoded and compressed motion vectors. The motion vectors provide information about portions of successive video frames which change in relative position. The motion vectors are decompressed and decoded along with the frames. In certain embodiments of the present invention, a first frame and an accompanying motion-vector table are transmitted from a processing component to a tim ing-controller component of a video-display device, using which the timing-controller component can generate a second frame that is displayed following display of the first frame.
