    • 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,并且彼此预测。 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跃,以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。

    • A system and method for implementing improved decoded picture buffer (DPB) management for scalable video coding and multiview video coding. To address the issue of mismatches in reference picture markings, all prior unnecessary reference pictures can be marked as unused after the decoding of an open decoding refresh (ODR), open layer refresh (OLR), or open view refresh (OVR) picture or, when scalable video coding (SVC) is at issue, an indication can be made in the stream that previous and current reference picture markings are identical. To address the occurrence of potential overflows in the decoded picture buffer, ODR, OLR, or OVR pictures may not be encoded if a switch can cause an overflow m the decoded picture buffer; all prior pictures may be removed from the decoded picture buffer; or prior pictures may removed from the DPB based on certain control indications. Solutions are also provided to address the issue of mismatches in bi-dependent leading pictures.
    • 一种用于实现用于可缩放视频编码和多视图视频编码的改进的解码图像缓冲器(DPB)管理的系统和方法。 为了解决参考图像标记中的不匹配问题,在解码开放解码刷新(ODR),开放层刷新(OLR)或打开视图刷新(OVR)图像之后,可以将所有先前不必要的参考图片标记为未使用, 当可伸缩视频编码(SVC)出现问题时,可以在流中进行指示,即先前和当前的参考图片标记是相同的。 为了解决解码图像缓冲器中潜在的溢出的发生,如果开关可能导致解码的图像缓冲器溢出,则ODR,OLR或OVR图像可能不被编码; 可以从解码图像缓冲器中去除所有先前的图像; 或者可以基于某些控制指示从DPB去除现有图像。 还提供了解决方案来解决双重依赖的主要图片中的不匹配问题。
