METHOD AND APPARATUS FOR WEIGHTED PREDICTION IN PREDICTIVE FRAMES

摘要

A method for constructing a picture under the control of an electronic device, comprising receiving a first weight parameter associated with a region of a first frame encoded with an encoding standard from a plurality of encoding standards; receiving a second weight parameter associated with a region of a second frame encoded with an encoding standard from the plurality of encoding standards; modifying the first weight parameter to conform to a universal bit configuration capable of representing weight parameters derived from any of the plurality of encoding standards; modifying the second weight parameter to conform to the universal bit configuration; calculating a first predicted component by applying the modified first weight parameter to the region of the first frame; calculating a second predicted component by applying the modified second weight parameter to the region of the second frame; and calculating a combined weighted prediction by combining the first predicted component and the second predicted component as well as a corresponding apparatus.
