Control of the inheritance of motion parameters (MPI) of the prediction subunit (SUB-PU) in the three-dimensional HEVC (3D) or other three-dimensional coding

摘要

A method of decoding a depth block, the method comprising: receiving a syntactic element indicating a size of a prediction subunit, sub-PU, for inheritance of motion parameters, MPI, in a depth prediction unit , Depth PU, where the depth PU comprises one or more sub-PU, where each sub-PU has a size equal to the size indicated by the syntactic element and where different movement information can be inherited for each sub- PU from a textured block cosituated with the respective sub-PU; and upon receiving an index value indicating that a candidate for merger or omission of MPI, based on a sub-PU MPI mode, can be used for motion prediction, inherit movement information for each sub-PU of the depth block, based, at least in part, on the corresponding texture blocks cosituted with each of the sub-PUs.
