Abstract: A method and apparatus for a three-dimensional or multi-view video encoding or decoding system utilizing unified disparity vector derivation is disclosed. When a three-dimensional coding tool using a derived disparity vector (DV) is selected, embodiments according to the present invention will first obtain the derived DV from one or more neighboring blocks. If the derived DV is available, the selected three-dimensional coding tool is applied to the current block using the derived DV. If the derived DV is not available, the selected three-dimensional coding tool is applied to the current block using a default DV, where the default DV is set to point to an inter-view reference picture in a reference picture list of the current block.

Abstract: A method of deriving VSP (View Synthesis Prediction) Merge candidates with aligned inter-view reference pictures is disclosed. The method generates a second Disparity Vector (DV) using a scaled DV derived from Neighboring Block Disparity Vector (NBDV) of the current block. A method of deriving one or more inter-view DV Merge candidates with aligned DV and associated inter-view reference pictures is also disclosed. The inter-view reference picture pointed by the DV derived from Depth oriented NBDV (DoNBDV) is used as the reference picture and the DV derived from DoNBDV is used as the DV for inter-view DV Merge candidate. Furthermore, a method of deriving temporal DV for NBDV is disclosed, where if the temporal neighboring block has a DV existing, the DV is used as an available DV for the current CU only if the associated inter-view reference picture exists in the reference lists of the current CU.

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.
