Abstract
An apparatus generally having a reference memory and a motion estimation circuit is disclosed. The reference memory may store reference samples used in a motion estimation of a current block beyond a boundary of a picture. The motion estimation circuit may (i) buffer the reference samples as copied from the reference memory, the reference samples as buffered residing both (a) inside the boundary and (b) inside a search window of the motion estimation, (ii) shift a sub-set of the reference samples to align with a corner of a sub-window, the sub-window being (a) completely within the search window and (b) at least partially outside of the boundary, (iii) fill an empty portion of the sub-window with copies of the reference samples within the sub-set and (iv) generate difference values by comparing the current block against the reference samples within the sub-window a plurality of times.
