Non-integer pixel sharing for video encoding

摘要

This disclosure describes video encoding techniques and video encoding devices that implement such techniques. In one embodiment, this disclosure describes a video encoding device comprising a motion estimator that generates non-integer pixel values for motion estimation, the motion estimator including a filter that receives at least three inputs of integer pixel values. The video encoding device also comprises a memory that stores the non-integer pixel values generated by the motion estimator, and a motion compensator that uses the stored non-integer pixel values for motion compensation.
