Abstract: A method and apparatus for Simplified Depth Coding (SDC) with extended Intra prediction modes are disclosed. Embodiments of the present invention use an extended Intra prediction mode set including Horizontal mode and Vertical mode. When the Horizontal mode is selected, the prediction samples for the current depth block are derived based on a reconstructed neighboring depth column adjacent to a left block boundary of the current depth block by generating rows of the prediction samples from the reconstructed neighboring depth column. When the Vertical mode is selected, the prediction samples for the current depth block are derived based on a reconstructed neighboring depth row adjacent to a top block boundary of the current depth block by generating columns of the prediction samples from the reconstructed neighboring depth row.

Abstract: A method and apparatus for deriving MVP (motion vector predictor) for Skip or Merge mode in 3D video coding are disclosed. In one embodiment, the method comprises determining an MVP candidate set for a selected block and selecting one MVP from an MVP list for motion vector coding of the block. The MVP candidate set may comprise multiple spatial MVP candidates associated with neighboring blocks and one inter-view candidate, and the MVP list is selected from the MVP candidate set. The MVP list may consist of only one MVP candidate or multiple MVP candidates. If only one MVP candidate is used, there is no need to incorporate an MVP index associated with the MVP candidate in the video bitstream corresponding to the three-dimensional video coding. Also, the MVP candidate can be the first available MVP candidate from the MVP candidate set according to a pre-defined order.

Abstract: A method and apparatus for deriving MVP (motion vector predictor) for a block for three-dimensional video coding or multi-view video coding are disclosed. Embodiments according to the present invention replace an unavailable inter-view MV of one neighboring block with a disparity vector derived from depth data of a subset of a depth block corresponding to one neighboring block. A method and apparatus for generating additional candidates for motion vector prediction associated with Merge mode or AMVP (Inter) mode for a block are disclosed. Embodiments according to the present invention generate one or more additional MVP candidates to add to the MVP list if the MVP list size is less than a given list size. The additional MVP candidates are generated either by reducing precision of an available MVP in the MVP list or by adding an offset to the available MVP in the MVP list.
