DISPARITY VECTOR DERIVATION

A parent block is partitioned into the plurality of blocks and a disparity vector derivation process is performed to derive a disparity vector for a representative block in the plurality of blocks. A video encoder generates a bitstream that includes a coded representation of the video data in part by performing, based on the derived disparity vector and without separately deriving disparity vectors for any block in the plurality of blocks other than the representative block, inter-view prediction for two or more blocks in the plurality of blocks. A video decoder reconstructs sample blocks for two or more blocks in the plurality of blocks in part by performing, based on the derived disparity vector and without separately deriving disparity vectors for any block in the plurality of blocks other than the representative block, inter-view prediction for the two or more blocks in the plurality of blocks.
