摘要： The techniques of this disclosure generally relate to using motion information for a corresponding block from a texture view component that corresponds with a block in a depth view component in coding the block in the depth view component. In some examples, for coding purposes, the techniques may use motion information when the spatial resolution of the texture view component is different than the spatial resolution of the depth view component. Among the various IMVP techniques described in this disclosure, this disclosure describes IVMP techniques for use in coding scenarios where a partition of a depth view macroblock (MB) corresponds to a texture view MB that is either intra coded or partitioned into four partitions.

摘要： 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 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.

摘要： A video coding device may be configured to code a bitstream including multiple views plus depth information. Two of the views may have reduced resolutions, while a third view may have a full resolution. The third view may be predicted relative to upsampled versions of the two reduced-resolution views. Each view may include texture data and depth data, such that a view component may include a texture component and a depth component. Moreover, the texture and depth components may be arranged within an access unit according to a particular order, which may simplify component extraction from the access unit.
