Abstract
Official abstract text for this publication.
An apparatus and method for deriving a motion vector predictor are disclosed. A search set comprising of multiple (spatial, or temporal) search MVs with priority is determined, wherein the search MVs for multiple neighboring reference block or one or more co-located reference blocks are configured into multiple search MV groups. In order to improve coding efficiency, embodiments according to the present invention, perform redundancy check every time after a search MV group is searched to determine whether an available search MV found. If an available search MV is found and the available search MV is not the same as a previously derived motion vector predictor (MVP), the available search MV is used as the MVP and the MVP derivation process terminates. Otherwise, the MVP derivation process moves to the next reference block. The search MV group can be configured to include different search MV(s) associated with reference blocks.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of deriving a motion vector predictor (MVP) for a motion, vector (MV) of a current block in Inter, or Merge, or Skip mode, the method being executed by a processor and comprising: receiving motion vectors (MVs) associated with reference blocks of the current block, wherein the reference blocks comprise at least one neighboring reference block of the current block; determining a spatial search set, wherein the spatial search set comprises at…
