Abstract:
Techniques related to decoder-side motion vector derivation (DMVD) are described. For example, this disclosure describes techniques related to applying one or more constraints to motion information, such as a motion vector (MV) derived by DMVD, and/or a MV difference between an initial MV and an MV derived by DMVD. When the constraint is applied to the DMVD, in certain examples, only the derived motion information which meets the constraint is regarded as valid motion information. Conditions may be placed on the constraints.

Claim (Index 6):
The method of  claim 1 , wherein determining that the first derived motion vector and the second derived motion vector have the pseudo symmetric motion vector difference comprises determining that:\n L 0_ MV _ X _Diff= L 1_ MV _ X _Diff, L 0_ MV _ Y _Diff= L 1_ MV _ Y _Diff, L 0_ MV _ X _Diff=\u22121* L 1_ MV _ X _Diff, or L 0_ MV _ Y _Diff=\u22121* L 1_ MV _ Y _Diff; wherein:\n L0_MV_X_Diff is an X component of a difference between a first initial motion vector and the first derived motion vector, \n L0_MV_Y_Diff is a Y component of a difference between the first initial motion vector and the first derived motion vector, \n L1_MV_X_Diff is an X component of a difference between a second initial motion vector and the second derived motion vector, and \n L1_MV_Y_Diff is a Y component of a difference between the second initial motion vector and the second derived motion vector.
