Abstract:
1. An apparatus, comprising: an encoder for encoding an image block by determining a motion estimation predictor for the image block using motion information previously generated from an element other than said encoder, and using the motion estimation predictor in a motion estimation process to generate a motion vector for the image block, wherein the motion estimation predictor is used in place of at least one predictor otherwise used in the motion estimation process, the at least one predictor being any of a search window predictor, a temporal predictor, and a block type predictor, wherein said encoder scales the motion information according to a temporal distance between a current picture that includes the image block and a reference picture used for the motion estimation process responsive to the reference picture used for the motion estimation process being different from a reference picture used to generate the motion information previously generated from the element other than said encoder.
