Claim 18:
19. The method of claim 1, wherein the method further comprises:
determining a first motion vector set for a fifth block which is bi-directional, wherein the first motion vector set comprises a first motion vector referring to a first reference picture in a reference picture list 0 for a first prediction direction and a second motion vector referring to a second reference picture in a second reference picture list 1 for a second prediction direction; and
in response to the fifth block satisfying a condition, converting the first motion vector set to a uni-directional motion vector, wherein motion information of one of the first prediction direction or the second prediction direction is discarded, wherein discarding the motion information comprises: modifying a reference index in the discarded prediction direction to −1,
wherein the uni-directional motion vector is used to update a History Motion Vector Prediction table,
wherein the condition comprises that a size of a luma component of the fifth block is same as a predefined size, wherein the second motion vector set is used for prediction of the fifth block, and wherein the predefined size comprises at least one of: 8×4, or 4×8.
