    • 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。
