Abstract: A method and apparatus for deriving a motion vector predictor (MVP) for a motion vector (MV) of a current block of a current picture in Inter, or Merge, or Skip mode. The method selects a co-located block corresponding to a co-located picture, receives one or more reference motion vectors (MVs) of one or more co-located reference blocks associated with the co-located block, and determines a search set that includes one or more search MVs associated with said one or more co-located reference blocks. The method further determines a search order for the search set having an order associated with a reference list attribute for a first search MV and a second search MV associated with an identical co-located reference block. Finally, the method determines the MVP for the current block based on the search set and the search order, and provides the MVP for the current block.

Abstract: A method and apparatus for 3D (three-dimensional) and multi-view video encoding or decoding of dependent-view texture or depth data using Merge mode with modified list size according to one or more 3D enabling flags are disclosed. An extra-candidate-number indicating one or more extra Merge candidates for the current block is determined according to one or more 3D enabling flags comprising a VSP (view synthesis prediction) flag. A modified list size for a 3D Merge list corresponding to a sum of the extra-candidate-number and an original list size is determined. The 3D Merge list with the modified list size is then determined based on original Merge candidates used to derive the base-view Merge list for video data in a base view and one or more 3D Merge candidates as enabled by the 3D enabling flags according to a priority order.

Abstract: Multi-view video encoding using early Merge mode decision and/or early CU split termination is disclosed. The present invention encodes a current coding block using the Merge/Skip mode without evaluating coding performance for at least one of Inter modes and Intra modes if the coding conditions associated with the current coding block and a neighboring block set of the current coding block are asserted. The coding conditions may correspond to whether the coding performance of the Skip mode is better than the coding performance of 2N×2N Merge mode for the current coding block and whether all blocks in the neighboring block set select the Merge mode or the Skip mode. Similarly, the process of splitting the current coding block into smaller coding blocks can be terminated without evaluating coding performance associated with the smaller coding blocks from splitting the current coding block if some coding conditions are asserted.

Abstract: A method and apparatus for deriving a motion vector predictor (MVP) for a motion vector (MV) of a current block of a current picture in Inter, or Merge, or Skip mode. The method selects a co-located block corresponding to a co-located picture and receives one or more reference motion vectors (MVs) of one or more co-located reference blocks associated with the co-located block. The method also determines a search set and determines a search order for the search set, if the search MV corresponding to the given reference list is not available, the search order then searches the search MV corresponding to a reference list different from the given reference list. Finally, the method determines the MVP for the current block based on the search set and the search order and provides the MVP for the current block.
