METHOD OF MOTION VECTOR PREDICTOR OR MERGE CANDIDATE DERIVATION IN VIDEO CODING

摘要

A method and apparatus for deriving directional-priority based candidates for a block coded in Inter, or Merge or Skip mode are disclosed. One or more motion vectors associated with one or more previously coded blocks for a current block are determined first. One or more directional-priority based candidates for the current block are derived by searching through the previously coded blocks according to a priority order associated with prediction direction of the motion vectors. The motion vectors having a first prediction direction are selected with a higher priority than the motion vectors having a second prediction direction. The derived directional-priority based candidates are inserted into a candidate list. The motion vector predictor (MVP) or Merge/Skip candidate is selected from the candidate list for coding the current block in Inter, or Merge or Skip mode.
