    摘要: This disclosure describes techniques for simplifying depth inter mode coding in a three-dimensional (3D) video coding process, such as 3D-HEVC. The techniques include generating a motion parameter candidate list, e.g., merging candidate list, for a current depth prediction unit (PU). In some examples, the described techniques include determining that a sub-PU motion parameter inheritance (MPI) motion parameter candidate is unavailable for inclusion in the motion parameter candidate list for the current depth PU if motion parameters of a co-located texture block to a representative block of the current depth PU are unavailable. In some examples, the described techniques include deriving a sub-PU MPI candidate for inclusion in the motion parameter candidate list for the current depth PU only if a partition mode of the current depth PU is 2N×2N.

    摘要: Embodiments of the present invention provide a method and an apparatus for predicting a residual, which method is applied to three-dimensional video encoding or multi-visual angle video encoding and comprises searching, when performing inter frame image prediction encoding on a prediction unit, a corresponding unit of the prediction unit in an adjacent visual angle encoded at the same time; and predicting a time domain predicted residual of the prediction unit by utilizing a time domain predicted residual of the corresponding unit in the encoded adjacent visual angle. The method is applied to three-dimensional video decoding or multi-visual angle video decoding and comprises judging, when performing inter frame image prediction decoding on a prediction unit, whether the prediction unit adopts a residual prediction; searching, if it is determined the prediction unit adopts the residual prediction, a corresponding unit of the prediction unit in an adjacent visual angle decoded at the same time; and predicting a predicted residual of the prediction unit by utilizing a time domain predicted residual of the corresponding unit in the decoded adjacent visual angle. The present invention improves video compression ratio and enhances encoding/decoding efficiencies.

    摘要: This disclosure describes techniques for constraining depth intra mode coding in a three-dimensional (3D) video coding process, such as 3D-High Efficiency Video Coding (3D-HEVC). In some examples, the techniques for constraining depth intra mode coding may prevent transform tree nodes from being split into sub-transform tree nodes when a depth prediction unit that corresponds to the transform tree node is predicted according to a depth modeling mode (DMM). In further examples, the techniques for constraining depth intra mode coding may prevent the DMM mode from being used when the maximum transform unit size that corresponds to a depth prediction unit is greater than the size of the depth prediction unit. The techniques for constraining depth intra mode coding may prevent characteristics of the DMM prediction modes used in 3D-HEVC and characteristics of the transform tree subdivision used in 3D-HEVC from interfering with each other.

    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.
