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 if the co-located image block has a list1 and a list0 motion vector. At least one motion vector of the bi-predictive block is derived by applying a bit operation to the selected motion vector.
