1. A system comprising:
a receiver configured to receive a bit stream including a coded representation of a picture, wherein the picture includes a plurality of largest coding units (LCUs) including a first LCU; and
a decoder coupled to the receiver, the decoder configured to:
derive a vertical position of a bottom right co-located motion vector associated with a current coding block;
determine that the vertical position of the bottom right co-located motion vector is not inside of the first LCU associated with the current coding block;
derive a position of a central co-located motion vector associated with the current coding block in response to determining that the vertical position of the bottom right co-located motion vector is not inside of the first LCU;
select motion data related to the central co-located motion vector as an inter-prediction candidate;
reconstruct the picture using the selected motion data; and
present the reconstructed picture via a display.
