Abstract
A method of three-dimensional video encoding or decoding that uses unified depth data access for VSP process and VSP-based merging candidate derivation is disclosed. When the coding tool corresponds to VSP process or VSP-based merging candidate, embodiments of the present invention fetch the same reference depth data in a reference view. A reference depth block in a reference view corresponding to the current texture CU is fetched using a derived DV (disparity vector). For the VSP process, first VSP data for a current PU (prediction unit) within the current CU is generated based on the reference depth block. For the VSP-based merging candidate derivation, second VSP data for a VSP-coded spatial neighboring PU associated with a VSP spatial merging candidates is generated also based on the reference depth block.
