Abstract
A video coder searches a set of neighbor blocks to generate a plurality of disparity vector candidates. Each of the neighbor blocks is a spatial or temporal neighbor of a current block. The video coder determines, based at least in part on the plurality of disparity vector candidates, a final disparity vector for the current block.
Claims29
A method of decoding video data, the method comprising:
- searching a set of neighbor blocks of the video data to generate a plurality of disparity vector candidates, wherein each of the neighbor blocks is a neighbor of a current block of the video data;
- determining, based at least in part on the plurality of disparity vector candidates, a final disparity vector for the current block;
- and
- reconstructing a sample block for the current block in part by performing, based on the final disparity vector for the current block, inter-view motion prediction or inter-view residual prediction for the current block.

A method of encoding video data, the method comprising:
- searching a set of neighbor blocks of the video data to generate a plurality of disparity vector candidates, wherein each of the neighbor blocks is a neighbor of a current block of the video data;
- determining, based at least in part on the plurality of disparity vector candidates, a final disparity vector for the current block;
- and
- generating a bitstream that includes a coded representation of the video data in part by performing, based on the final disparity vector for the current block, inter-view motion prediction or inter-view residual prediction for the current block.
