Abstract
Motion vectors are predicted for a current block of a current frame using motion vectors from previous frames in the video stream. Temporal distances between a current frame and the one or more reference frames used to predict a current block and temporal distances between the previous frame and its reference frames are determined. Temporal distances for current frames and previous frames can be combined to weight the motion vectors and improve motion vector prediction.
