1. A method of processing video data, the method comprising:

  • determining first motion information for a prediction unit (PU) of a coding unit (CU) of a video block from neighboring blocks of the PU according to a backward view synthesis prediction (BVSP) mode, wherein the first motion information includes at least one disparity motion vector and an associated reference view index that identifies an inter-view reference picture;

    partitioning the PU into two or more sub-PUs;

    determining second motion information for each of the sub-PUs, wherein the second motion information includes at least one disparity motion vector associated with a depth block of the inter-view reference picture corresponding to each of the sub-PUs;

    performing motion compensation to predict each of the sub-PUs from the inter-view reference picture based on the second motion information; and

    storing the second motion information for each of the sub-PUs of the PU in a memory to be used for predicting subsequent PUs.
