    Abstract: 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.

    Abstract: In an example, a method of processing video data includes determining a candidate motion vector for deriving motion information of a current block of video data, where the motion information indicates motion of the current block relative to reference video data. The method also includes determining a derived motion vector for the current block based on the determined candidate motion vector, where determining the derived motion vector comprises performing a motion search for a first set of reference data that corresponds to a second set of reference data outside of the current block.

    Abstract: In an example, a method of coding video data may include selecting, as part of an entropy coding process, a context for a syntax element associated with a current coding unit (CU) based on information relating to CU depth of one or more neighboring CUs relative to the current CU. The syntax element may represent whether the current CU is split into sub-CUs. The method may include entropy coding the syntax element based on the selected context.

    Abstract: Techniques are described where if an inter-view predicted motion vector candidate (IPMVC) and an inter-view disparity motion vector candidate (IDMVC) are derived based on a shifted disparity vector, where the amount by which the disparity vector is shifted for the IPMVC and IDMVC is different. The techniques also prioritize the inclusion of the IPMVC over the IDMVC in a candidate list, and prune the IPMVC and the IDMVC if there is a duplicated IPMVC or IDMVC in the candidate list.
