Abstract
The present disclosure provides a method and an apparatus for rounding a coordinate value of a non-integer pixel position motion vector. The method includes: rounding a coordinate value of a non-integer pixel position motion vector, which includes: for each dimension of coordinates of the non-integer pixel position motion vector, when a coordinate in the dimension is a non-integer pixel position, rounding the coordinate value of the non-integer pixel position motion vector in the dimension to one of integer pixel coordinate positions A and B if distances from the coordinate of the non-integer pixel position motion vector in the dimension to the integer pixel coordinate positions A and B adjacent to the non-integer pixel position in the dimension are the same, where an integer pixel coordinate position is determined by a sign of the coordinate value of the non-integer pixel position motion vector in the dimension.
