Method and apparatus of motion vector prediction or merge candidate derivation for video coding

摘要

A method and apparatus of priority-based MVP (motion vector predictor) derivation for motion compensation in a video encoder or decoder are disclosed. According to this method, one or more final motion vector predictors (MVPs) are derived using priority-based MVP derivation process. The one or more final MVPs are derived by selecting one or more firstly available MVs from a priority-based MVP list for Inter prediction mode, Skip mode or Merge mode based on reference data of one or two target reference pictures that are reconstructed prior to the current block according to a priority order. Therefore, there is no need for transmitting information at the encoder side nor deriving information at the decoder side that is related to one or more MVP indices to identify the one or more final MVPs in the video bitstream.
