    • A video coder may perform a simplified depth coding (SDC) mode, including simplified residual coding, to code a depth block according to any of a variety of, e.g., at least three, depth intra prediction modes. For example, the video coder may perform the SDC mode for coding a depth block according to depth modeling mode (DMM) 3, DMM 4, or a region boundary chain coding mode. In such examples, the video coder may partition the depth block, and code respective DC residual values for each partition. In some examples, the video coder may perform the SDC mode for coding a depth block according to an intra prediction mode, e.g., an HEVC base specification intra prediction mode, such as a DC intra prediction mode or one of the directional intra prediction modes. In such examples, the video coder may code a single DC residual value for the depth block.
    • 视频译码器可执行包含简化残差译码的简化深度译码(SDC)模式以根据多种(例如,至少三种)深度帧内预测模式中的任一者对深度块进行译码 。 例如,视频译码器可根据深度建模模式(DMM)3,DMM4或区域边界链编码模式执行用于编码深度块的SDC模式。 在这样的示例中,视频编码器可以对深度块进行分区,并对每个分区的相应DC残差值进行编码。 在一些示例中,视频译码器可执行SDC模式以根据例如HEVC基本规格帧内预测模式(例如DC帧内预测模式或定向帧内预测模式中的一者)的帧内预测模式译码深度块。 在这样的示例中,视频编码器可以编码深度块的单个DC残余值。

    • This disclosure describes techniques for signaling and processing information indicating simplified depth coding (SDC) for depth intra-prediction and depth inter- prediction modes in a 3D video coding process, such as a process defined by the 3D- HEVC extension to HEVC. In some examples, the disclosure describes techniques for unifying the signaling of SDC for depth intra-prediction and depth inter-prediction modes in 3D video coding. The signaling of SDC can be unified so that a video encoder or video decoder uses the same syntax element for signaling SDC for both the depth intra- prediction mode and the depth inter-prediction mode. Also, in some examples, a video coder may signal and/or process a residual value generated in the SDC mode using the same syntax structure, or same type of syntax structure, for both the depth intra- prediction mode and depth inter-prediction mode.
    • 本公开描述了用于在3D视频编码过程(诸如由HEVC的3D-HEVC扩展定义的过程)中用于指示用于深度帧内预测和深度帧间预测模式的简化深度编码(SDC)的信令和处理信息的技术。 在一些示例中,本公开描述了用于在3D视频编码中统一SDC的信令用于深度帧内预测和深度帧间预测模式的技术。 SDC的信令可以被统一,使得视频编码器或视频解码器使用相同的语法元素用于信令SDC用于深度帧内预测模式和深度帧间预测模式。 此外,在一些示例中,视频编码器可以使用与深度帧内预测模式和深度帧间预测模式两者相同的语法结构或相同类型的语法结构信号和/或处理在SDC模式中生成的残差值 。
