Abstract:
In one embodiment, the method includes selecting the list0 motion vector of the co-located image block for the bi-predictive image block as a motion vector for deriving motion vectors of the bi-predictive image block regardless of whether the co-located block includes a list1 motion vector. The selected motion vector of the co-located block in the reference picture is scaled based on a temporal distance between a current picture and the reference picture. The current picture includes the bi-predictive block. The motion vector of the bi-predictive block is derived based on the scaled motion vector of the co-located block.
