摘要
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.
