摘要： An apparatus for coding video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a first layer having a first spatial resolution and a corresponding second layer having a second spatial resolution, wherein the first spatial resolution is less than the second spatial resolution. The video information includes at least motion field information associated with the first layer. The processor upsamples the motion field information associated with the first layer. The processor further adds an inter-layer reference picture including the upsampled motion field information in association with an upsampled texture picture of the first layer to a reference picture list to be used for inter prediction. The processor may encode or decode the video information.

摘要： Techniques are described for deriving a disparity vector for a current block based on a disparity motion vector of a neighboring block in a 3D-AVC video coding process. The disparity vector derivation allows for texture-first coding where a depth view component of a dependent view is coded subsequent to the coding of the corresponding texture component of the dependent view.

摘要： A video encoder generates a syntax element that indicates whether a video unit of a current picture is predicted from an external picture. The external picture is in a different layer than the current picture. Furthermore, the video encoder outputs a video data bitstream that includes a representation of the syntax element. The video data bitstream may or may not include a coded representation of the external picture. A video decoder obtains the syntax element from the video data bitstream. The video decoder uses the syntax element in a process to reconstruct video data of a portion of the video unit.

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： In general, this disclosure describes techniques for simplifying SDC coding of large intra-prediction blocks, such as 64×64 blocks, in a 3D video coding process, such as 3D-HEVC. In some examples, the techniques may include processing 64×64 intra-prediction blocks as four 32×32 intra-prediction blocks in intra SDC. Processing large intra-prediction blocks as multiple, smaller intra-prediction blocks in intra SDC may reduce maximum buffer size requirements in the intra SDC process.
摘要翻译：一般而言，本发明描述用于在3D视频译码过程（例如，3D-HEVC）中简化诸如64×64块的大的帧内预测块的SDC译码的技术。在一些实例中，所述技术可包含将64×64帧内预测块处理为SDC内的四个32×32帧内预测块。将较大的帧内预测块处理为SDC内部的多个较小的帧内预测块可以减少帧内SDC处理中的最大缓冲区大小要求。
