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.
