Abstract: A method and apparatus for deriving a motion vector predictor (MVP) are disclosed. The MVP is selected from spatial MVP and temporalone or more MVP candidates. The method determines a value of a flag in a video bitstream, where the flag is utilized for selectively disabling use of one or more temporal MVP candidates for motion vector prediction. The method selects, based on an index derived from the video bitstream, the MVP from one or more non-temporal MVP candidates responsive to the flag indicating that said one or more temporal MVP candidates are not to be utilized for motion vector prediction. Further, the method provides the MVP for the current block.

Abstract: A method and apparatus for three-dimensional video encoding or decoding using sub-block based inter-view prediction are disclosed. The method partitions a texture block into texture sub-blocks and determines disparity vectors of the texture sub-blocks. The inter-view reference data is derived based on the disparity vectors of the texture sub-blocks and a reference texture frame in a different view. The inter-view reference data is then used as prediction of the current block for encoding or decoding. One aspect of the present invention addresses partitioning the current texture block. Another aspect of the present invention addresses derivation of disparity vectors for the current texture sub-blocks.
