    Abstract: A prediction unit (PU) of a coding unit (CU) is split into two or more sub-PUs including a first sub-PU and a second sub-PU. A first motion vector of a first type is obtained for the first sub-PU and a second motion vector of the first type is obtained for the second sub-PU. A third motion vector of a second type is obtained for the first sub-PU and a fourth motion vector of the second type is obtained for the second sub-PU, such that the second type is different than the first type. A first portion of the CU corresponding to the first sub-PU is coded according to advanced residual prediction (ARP) using the first and third motion vectors. A second portion of the CU corresponding to the second sub-PU is coded according to ARP using the second and fourth motion vectors.

    Abstract: Techniques are described for encoding and decoding depth data for three-dimensional (3D) video data represented in a multiview plus depth format using depth coding modes that are different than high-efficiency video coding (HEVC) coding modes. Examples of additional depth intra coding modes available in a 3D-HEVC process include at least two of a Depth Modeling Mode (DMM), a Simplified Depth Coding (SDC) mode, and a Chain Coding Mode (CCM). In addition, an example of an additional depth inter coding mode includes an Inter SDC mode. In one example, the techniques include signaling depth intra coding modes used to code depth data for 3D video data in a depth modeling table that is separate from the HEVC syntax. In another example, the techniques of this disclosure include unifying signaling of residual information of depth data for 3D video data across two or more of the depth coding modes.

    Abstract: A device for decoding video data is configured to determine, based on a chroma sampling format for the video data, that adaptive color transform is enabled for one or more blocks of the video data; determine a quantization parameter for the one or more blocks based on determining that the adaptive color transform is enabled; and dequantize transform coefficients based on the determined quantization parameter. A device for decoding video data is configured to determine for one or more blocks of the video data that adaptive color transform is enabled; receive in a picture parameter set, one or more offset values in response to adaptive color transform being enabled; determine a quantization parameter for a first color component of a first color space based on a first of the one or more offset values; and dequantize transform coefficients based on the quantization parameter.

    Abstract: A video coder generates a list of merging candidates for coding a video block of the 3D video. A maximum number of merging candidates in the list of merging candidates may be equal to 6. As part of generating the list of merging candidates, the video coder determines whether a number of merging candidates in the list of merging candidates is less than 5. If so, the video coder derives one or more combined bi-predictive merging candidates. The video coder includes the one or more combined bi-predictive merging candidates in the list of merging candidates.
