1. A method for constructing a predicted picture, comprising:

  • modifying a first weight parameter associated with a region of a first frame to conform to a bit configuration;

    modifying a second weight parameter associated with a region of a second frame to conform to the 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.
