Abstract
A video coding device generates a motion vector (MV) candidate list for a prediction unit (PU) of a coding unit (CU) that is partitioned into four equally-sized PUs. The video coding device converts a bi-directional MV candidate in the MV candidate list into a uni-directional MV candidate. In addition, the video coding device determines a selected MV candidate in the merge candidate list and generates a predictive video block for the PU based at least in part on one or more reference blocks indicated by motion information specified by the selected MV candidate.
