Abstract: A method and apparatus for three-dimensional video encoding or decoding using an improved refined DV derivation process are disclosed. Embodiments according to the present invention first determine a derived DV (disparity vector) from temporal, spatial, or inter-view neighboring blocks, or any combination thereof of the current block in a dependent view. A refined DV is then determined based on the derived DV when the derived DV exists and is valid. When the derived DV does not exist or is not valid, the refined DV is determined based on a zero DV or a default DV. The derived DV, the zero DV, or the default DV is used respectively to locate a corresponding block in a coded view, and a corresponding depth block in the coded view is used to determine the refined DV.

Abstract: A method and apparatus for spatial motion vector prediction (MVP) candidate derivation for Direct mode and Skip mode in three-dimensional video coding are disclosed. The motion vector of each neighboring block is associated with a corresponding reference picture index pointing to a corresponding reference picture. For both the Direct mode and the Skip mode, the motion vector of each neighboring block is selected as the spatial MVP candidate for each neighboring block only if the corresponding reference picture index is the same as a selected target reference picture index. In one embodiment, the target reference picture index is set to 0. In another embodiment, the target reference picture index corresponds to a majority of the corresponding reference picture indexes associated with the neighboring blocks in Direct mode or Skip mode.

Abstract: A method for providing compatible depth-dependent coding and depth-independent coding in three-dimensional video encoding or decoding is disclosed. The compatible system uses a depth-dependency indication to indicate whether depth-dependent coding is enabled for a texture picture in a dependent view. If the depth-dependency indication is asserted, second syntax information associated with a depth-dependent coding tool is used. If the depth-dependent coding tool is asserted, the depth-dependent coding tool is applied to encode or decode the current texture picture using information from a previously coded or decoded depth picture. The syntax information related to the depth-dependency indication can be in Video Parameter Set (VPS), Sequence Parameter Set (SPS), Picture Parameter Set (PPS) or Slice Header.
