Abstract
A more efficient motion estimation process that utilizes a plurality of predicted start points (e.g., two predicted start points) based on blocks adjacent to the current block together with other improvements and requires minimal system resources (e.g., hardware resources and CPU processing) in its hardware implementation is provided. More particularly, the motion estimation technique in accordance with the present invention performs a plurality of coarse searches (either sequentially or in parallel) using a plurality of predicted start positions followed by a fine search.
