1. A method for determining a merged motion information unit set i for a picture block x, the method comprising:
determining K1 pixel samples of the picture block x;
determining a candidate motion information unit set associated with each pixel sample in the K1 pixel samples,
wherein the candidate motion information unit set associated with each pixel sample consists of one candidate motion information unit, and K1 is an integer that is greater than or equal to 2; and
determining the merged motion information unit set i comprising K1 motion information units,
wherein the K1 motion information units in the merged motion information unit set i are candidate motion information units of candidate motion information unit sets associated with the K1 pixel samples,
wherein each motion information unit comprises at least one of a motion vector whose prediction direction is forward and a motion vector whose prediction direction is backward,
wherein reference frame indices associated with the K1 motion information units in the merged motion information unit set i are the same, and
wherein the merged motion information unit set i is associated with an identifier.
