摘要： This disclosure relates to techniques for constructing a combined reference picture list, List C, based on List 0 and List 1, used for uni-directional prediction of video blocks in any direction. The techniques include coding one or more syntax elements defined to indicate construction information for List C, and performing reference picture list construction for List C from List 0 and List 1 based on the syntax elements. The one or more syntax elements may indicate that List C is used for uni-directional prediction, and may also indicate a number of reference pictures identified in List C and a reference index of a reference picture for each entry in List C. Each coded video block of a B slice may have an associated syntax element, i.e., inter_pred_idc, to indicate whether the video block is bi-predicted from List 0 and List 1 (Bi) or uni-directional predicted from List C (Pred_LC).

摘要： A video coder may utilize large macroblocks having more than 16x16 pixels. Syntax for the large macroblocks may define whether a bitstream includes large macroblocks, such as superblocks having 64x64 pixels or bigblocks having 32x32 pixels. The syntax may be included in a slice header or a sequence parameter set. The large macroblocks may also be encoded according to a large macroblock syntax. The bitstream may further include syntax data that indicates a level value based on whether the bitstream includes any of the large macroblocks, for example, as a smallest-sized luminance prediction block. A decoder may use the level value to determine whether the decoder is capable of decoding the bitstream.

摘要： This disclosure describes techniques for 3D video coding. In particular, this disclosure is related to techniques for advanced residual prediction (ARP) in 3D-HEVC. According to one techniques of this disclosure, when performing inter-view ARP for a bi-directionally predicted block, the video coder may determine a motion vector for a first corresponding block as part of performing ARP for a first prediction direction and reuse that determined motion vector when performing ARP for a second prediction direction. According to another technique, for a bi-directionally predicted block, a video coder may apply ARP in only one direction for a chroma component of a block but apply ARP in two directions for a luma component of the block. According to another technique, a video coder may selectively apply ARP to chroma components based on block size. These simplifications, as well as other techniques included in this disclosure, may reduce overall coding complexity.
摘要翻译：本公开描述了用于3D视频编码的技术。特别地，本公开涉及3D-HEVC中的高级剩余预测（ARP）技术。根据本公开的一种技术，当为双向预测块执行视频间ARP时，视频编码器可以为第一对应块确定运动向量，作为对第一预测方向执行ARP的一部分，并重新使用所确定的运动执行第二预测方向的ARP时的向量。根据另一技术，对于双向预测的块，视频编码器可以在块的色度分量的一个方向上应用ARP，但是对于块的亮度分量在两个方向上应用ARP。根据另一技术，视频编码器可以基于块大小选择性地将ARP应用于色度分量。这些简化以及本公开中包括的其他技术可以降低整体编码复杂度。

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 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.

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.
