Method and apparatus for removing redundancy in motion vector predictors

A video coding apparatus for coding a current block in an Inter, Merge, or Skip mode, the apparatus comprising one or more electronic circuits configured to:

• determine neighboring blocks of the current block of a current picture, wherein the current picture is divided into a plurality of prediction units (PU s), wherein the current block is a PU of the current picture;
• determine a motion vector predictor (MVP) candidate set from MVP candidates associated with the neighboring blocks;
• identify a redundant MVP candidate among the MVP candidate set based on at least one of:
• determine a first MVP candidate and a second MVP candidate in the MVP candidate set are 1) within a same PU (Prediction Unit) that is adjacent to the current block and 2) in the current picture and, in response, determine that the first MVP is the redundant MVP candidate;
• and
• determine a third MVP candidate in the MVP candidate set is associated with a neighboring block which is in a same coding unit (CU) as the current block, previously partitioned from the current block, and has a PU size different from the current block, and, in response, determine that the third MVP is the redundant MVP candidate;
• provide a modified MVP candidate set for determining a final MVP, wherein the modified MVP candidate set corresponds to the MVP candidate set except the determined redundant MVP candidate;
• and
• encode or decode the current block according to the final MVP.
