    • This disclosure describes techniques for constraining depth intra mode coding in a three-dimensional (3D) video coding process, such as 3D-High Efficiency Video Coding (3D-HEVC). In some examples, the techniques for constraining depth intra mode coding may prevent transform tree nodes from being split into sub-transform tree nodes when a depth prediction unit that corresponds to the transform tree node is predicted according to a depth modeling mode (DMM). In further examples, the techniques for constraining depth intra mode coding may prevent the DMM mode from being used when the maximum transform unit size that corresponds to a depth prediction unit is greater than the size of the depth prediction unit. The techniques for constraining depth intra mode coding may prevent characteristics of the DMM prediction modes used in 3D-HEVC and characteristics of the transform tree subdivision used in 3D-HEVC from interfering with each other.
    • 本公开描述了在3D-高效率视频编码(3D-HEVC)三维(3D)视频编码处理中约束深度帧内模式编码的技术。 在一些示例中,当根据深度建模模式(DMM)预测与变换树节点对应的深度预测单元时,用于约束深度帧内模式编码的技术可以防止变换树节点被分割成子变换树节点。 在另外的例子中,当对应于深度预测单元的最大变换单位大小大于深度预测单元的大小时,用于约束深度帧内模式编码的技术可以防止DMM模式被使用。 限制深度帧内模式编码的技术可以防止在3D-HEVC中使用的DMM预测模式的特征和在3D-HEVC中使用的变换树细分的特征彼此干扰。

    • This disclosure describes techniques for simplifying depth inter mode coding in a three-dimensional (3D) video coding process, such as 3D-HEVC. The techniques include generating a motion parameter candidate list, e.g., merging candidate list, for a current depth prediction unit (PU). In some examples, the described techniques include determining that a sub-PU motion parameter inheritance (MPI) motion parameter candidate is unavailable for inclusion in the motion parameter candidate list for the current depth PU if motion parameters of a co-located texture block to a representative block of the current depth PU are unavailable. In some examples, the described techniques include deriving a sub-PU MPI candidate for inclusion in the motion parameter candidate list for the current depth PU only if a partition mode of the current depth PU is 2N×2N.
    • 本公开描述了用于简化3D-HEVC等三维(3D)视频编码处理中的深度帧间编码的技术。 这些技术包括为当前深度预测单元(PU)生成运动参数候选列表,例如合并候选列表。 在一些示例中,所描述的技术包括确定如果将位于同一个位置的纹理块的运动参数传送到一个或多个运动参数继承(MPI)运动参数候选者的运动参数,则不能使用用于当前深度PU的运动参数候选列表 当前深度PU的代表块不可用。 在一些示例中,所描述的技术包括仅当当前深度PU的分区模式是2N×2N时,才导出用于当前深度PU的运动参数候选列表中的子PU MPI候选。
