Abstract: A method and apparatus for three-dimensional video coding using the virtual depth information are disclosed. For a current texture block in the dependent view, the method incorporating the present invention first derives an estimated disparity vector to locate a corresponding texture block in a coded view. A collocated depth block in the coded view collocated with the corresponding texture block in the coded view is identified and used to derive the virtual depth information. One aspect of the present invention addresses derivation process for the estimated disparity vector. Another aspect of the present invention addresses the usage of the derived virtual depth information.

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: An apparatus and method for temporal motion vector prediction for a current block in a picture are disclosed. In the present method, one temporal block in a first reference picture in a first list selected from a list group comprising list 0 and list 1 is determined. When the determined temporal block has at least one motion vector, a candidate set is determined based on the motion vector of the temporal block. The temporal motion vector predictor or temporal motion vector predictor candidate or temporal motion vector or temporal motion vector candidate for the current block is determined from the candidate set by checking a presence of a motion vector pointing to a reference picture in a first specific list in said at least one motion vector, wherein the first specific list is selected from the list group based on a priority order.

Abstract: A method for deriving a motion vector predictor (MVP) receives motion vectors (MVs) associated with reference blocks of the current block. The method determines at least one first spatial search MV associated with a first MV searching order and at least one second spatial search MV associated with a second MV searching order for each neighboring reference block. Then, the method determines whether a first available-first spatial search MV exists for said at least one neighboring reference block according to the first MV searching order, and provides the first available-first spatial search MV as a spatial MVP for the current block. Finally, the method determines whether a first available-second spatial search MV exists for said at least one neighboring reference block according to the second MV searching order only if none of first spatial search MVs for said at least one neighboring reference block is available.

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.

Abstract: An apparatus and method of deriving a motion vector predictor (MVP) for a current MV of a current block in Inter, Merge or Skip mode are disclosed based on motion vector (MV) attribute search. The system determines first MV attribute search comprising whether a given MV pointing to the target reference picture in the given reference list, or whether the given MV pointing to the target reference picture in other reference list, and determines second MV attribute search comprising whether the given MV pointing to other reference pictures in the given reference list, or whether the given MV pointing to the other reference pictures in the other reference list. The MVP for the current block is then determined from the neighboring blocks according to a search order.

Abstract: The invention provides a motion prediction method. First, a plurality of candidate units corresponding to a current unit of a current frame is determined. A plurality of motion vectors of the candidate units is then obtained. A plurality of scaling factors of the candidate units is then calculated according to a plurality of respective temporal distances depending on a plurality of reference frames of the motion vectors. The motion vectors of the candidate units are then scaled according to the scaling factors to obtain a plurality of scaled motion vectors. The scaled motion vectors are ranked, and a subset of highest ranking motion vectors are identified to be included in a candidate set. Finally, a motion vector predictor for motion prediction of the current unit is then selected from the candidate units.
