1. A method for decoding video data, the method comprising: performing a disparity vector derivation process to derive a disparity vector for a representative block in a plurality of blocks, wherein the video data includes a parent block that is partitioned into the plurality of blocks; and reconstructing 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.
