Abstract: This disclosure describes techniques for simplifying delta DC residual coding in a 3D video coding process, such as 3D-HEVC. In some examples, the techniques may modify binarization and/or context modeling processes to reduce the complexity of entropy coding of one or more syntax elements used to represent delta DC residual values.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In an example, a method of decoding video data includes selecting a motion information derivation mode from a plurality of motion information derivation modes for determining motion information for a current block, where each motion information derivation mode of the plurality comprises performing a motion search for a first set of reference data that corresponds to a second set of reference data outside of the current block, and where the motion information indicates motion of the current block relative to reference video data. The method also includes determining the motion information for the current block using the selected motion information derivation mode. The method also includes decoding the current block using the determined motion information and without decoding syntax elements representative of the motion information.
