摘要：
A video coding method for deriving motion vectors for a bi-predictive block is disclosed, the method comprising: obtaining a reference picture of the bi-predictive block; determining a motion vector of the bi-predictive block; and decoding the bi-predictive block based on the determined motion vector, characterized in that the determining the motion vector of the bi-predictive block comprising setting the motion vector of the bi-predictive block equal to a motion vector of the co-located block in the reference picture, when the reference picture is a long-term reference picture.
