Abstract:
Method and apparatus of using motion refinement with reduced bandwidth are disclosed. According to one method, a predictor refinement process is applied to generate motion refinement for the current block by searching among multiple motion vector candidates using reference data comprising the target motion-compensated reference block, where if a target motion vector candidate requires target reference data from the target motion-compensated reference block being outside the valid reference block, the target motion vector candidate is excluded from said searching the multiple motion vector candidates or a replacement motion vector candidate closer to a center of the corresponding block of the current block is used as a replacement for the target motion vector candidate. In another method, if a target motion vector candidate belongs to one or more target fractional-pixel locations, a reduced tap-length interpolation filter is applied to the target motion vector candidate.

Claim (Index 11):
The apparatus of  claim 10 , wherein the predictor refinement process corresponds to Pattern-based MV derivation (PMVD), Bi-directional optical flow (BIO) or Decoder-side MV refinement (DMVR).
