    • 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。
