    • Joint coding of depth map video and texture video is provided, where a motion vector for a texture video is predicted from a respective motion vector of a depth map video or vice versa. For scalable video coding, depth map video is coded as a base layer and texture video is coded as an enhancement layer(s). Inter-layer motion prediction predicts motion in texture video from motion in depth map video. With more than one view in a bit stream (for multi view coding), depth map videos are considered monochromatic camera views and are predicted from each other. If joint multi-view video model coding tools are allowed, inter-view motion skip issued to predict motion vectors of texture images from depth map images. Furthermore, scalable multi-view coding is utilized, where interview prediction is applied between views in the same dependency layer, and inter-layer (motion) prediction is applied between layers in the same view.
    • 提供深度图视频和纹理视频的联合编码,其中从深度图视频的相应运动矢量预测纹理视频的运动矢量,反之亦然。 对于可伸缩视频编码,深度图视频被编码为基础层,纹理视频被编码为增强层。 层间运动预测从深度图视频中的运动中预测纹理视频中的运动。 在一个比特流中有多个视图(用于多视图编码),深度图视频被认为是单色相机视图,并且被相互预测。 如果允许联合多视图视频模型编码工具,则会发出视频间的动态跳过来预测来自深度图图像的纹理图像的运动矢量。 此外,利用可扩展的多视图编码,其中在同一依赖层中的视图之间应用访问预测,并且在相同视图中的层之间应用层间(运动)预测。

    • 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.

    • In one example, a video decoder is configured to determine, from data associated with an open decoding refresh (ODR) picture of video data, an identifier for a previous picture of the video data, determine whether the previous picture is currently stored in a reference picture memory, and decode only data for pictures of the video data having display order values that are greater than a display order value of the ODR picture, when the previous picture is not stored in the reference picture memory. In another example, a video encoder is configured to encode an open decoding refresh (ODR) picture, determine a previously coded picture having a display order value less than a display order value of the ODR picture and having a temporal identifier value equal to zero, and signal syntax data for the ODR picture representative of an identifier of the determined previously coded picture.
