US Patent 9525861 Disparity vector prediction in video coding

Techniques are described for determining a disparity vector for a current block based on disparity motion vectors of one or more spatially and temporally neighboring regions to a current block to be predicted. The spatially and temporally neighboring regions include one or a plurality of blocks, and the disparity motion vector represents a single vector in one reference picture list for the plurality of blocks within the spatially or temporally neighboring region. The determined disparity vector could be used to coding tools which utilize the information between different views such as merge mode, advanced motion vector prediction (AMVP) mode, inter-view motion prediction, and inter-view residual prediction.
