Abstract
A system and method which determines an adaptive vertical search range used to provide motion estimation in digital video content are disclosed. In some embodiments, a fixed-size vertical search range for the motion estimation is defined and utilized. A reference frame and target frame are stored in memory, and a block in the reference frame is selected for consideration. An offset value is determined which is indicative of a directional shift of the fixed-size vertical search range and the vertical search range is shifted based on the offset value. A motion vector is then estimated using the shifted vertical search range.
