Abstract: The techniques of this disclosure generally relate to using motion information for a corresponding block from a texture view component that corresponds with a block in a depth view component in coding the block in the depth view component. In some examples, for coding purposes, the techniques may use motion information when the spatial resolution of the texture view component is different than the spatial resolution of the depth view component. Among the various IMVP techniques described in this disclosure, this disclosure describes IVMP techniques for use in coding scenarios where a partition of a depth view macroblock (MB) corresponds to a texture view MB that is either intra coded or partitioned into four partitions.

Abstract: In general, techniques are described for lookup table coding. A device comprising one or more processors and a memory may be configured to perform the techniques. The processors are configured to receive at least one difference table including a set of values, each value of the set being included or not included in the reference lookup table and generate a current lookup table based on the reference lookup table and the difference table. The current lookup table may include at least one of a value from the difference table that is not included in the reference table or a value from the reference table that is not included in the difference table. The one or more processors may then decode the video data based on a set of values of the current lookup table. The memory may be configured to store the current lookup table.

Abstract: In accordance with one or more techniques of this disclosure, a video coder may divide a current prediction unit (PU) into a plurality of sub-PUs. Each of the sub-PUs may have a size smaller than a size of the PU. Furthermore, the current PU may be in a depth view of the multi-view video data. For each respective sub-PU from the plurality of sub-PUs, the video coder may identify a reference block for the respective sub-PU. The reference block may be co-located with the respective sub-PU in a texture view corresponding to the depth view. The video coder may use motion parameters of the identified reference block for the respective sub-PU to determine motion parameters for the respective sub-PU.
