Abstract: In general, the disclosure describes techniques for coding depth blocks in video data. A video coding device may determine a size of a sub-prediction unit (sub-PU) for motion parameter inheritance (MPI) in a depth prediction unit (depth PU). The depth PU may comprise one or more sub-PUs, each sub-PU having equal size. Distinct motion information can be inherited for each sub-PU from a texture block co-located to the sub-PU. The device may encode each sub-PU based on MPI corresponding to texture blocks co-located with the sub-PUs and generate a syntax element that indicates the size of each sub-PU for MPI. The device may further receive the syntax element, and, upon receiving an index value that indicates a sub-PU MPI mode, inherit MPI for each sub-PU based on the corresponding texture blocks.

Abstract: Techniques are described for sub-prediction unit (PU) based motion prediction for video coding in HEVC and 3D-HEVC. In one example, the techniques include an advanced temporal motion vector prediction (TMVP) mode to predict sub-PUs of a PU in single layer coding for which motion vector refinement may be allowed. The advanced TMVP mode includes determining motion vectors for the PU in at least two stages to derive motion information for the PU that includes different motion vectors and reference indices for each of the sub-PUs of the PU. In another example, the techniques include storing separate motion information derived for each sub-PU of a current PU predicted using a sub-PU backward view synthesis prediction (BVSP) mode even after motion compensation is performed. The additional motion information stored for the current PU may be used to predict subsequent PUs for which the current PU is a neighboring block.
