Abstract: Techniques are described for determining a block in a reference picture in a reference view based on a disparity vector for a current block. The techniques start the disparity vector from a bottom-right pixel in a center 2×2 sub-block within the current block, and determine a location within the reference picture to which the disparity vector refers. The determined block covers the location referred to by the disparity vector based on the disparity vector starting from the bottom-right pixel in the center 2×2 sub-block within the current block.

Abstract: A method, apparatus, and manufacture for processing video data. A list of output layer sets in a video bitstream is received, and an index to at least one target output layer set in the list of output layer sets is received. Next, target output layers in the at least one target output layer set is determined based on the index. At least the target output layers from the video bitstream are decoded. Then, the decoded target output layers are output without outputting layers that are not targeted for output.

Abstract: A method of coding video data includes receiving one or more layers of video information. Each layer may include at least one picture. The method can include processing an indicator within at least one of a video parameter set (VPS), a sequence parameter set (SPS), or a picture parameter set (PPS) that indicates whether all direct reference layer pictures associated with the at least one of the video parameter set (VPS), the sequence parameter set (SPS), or the picture parameter set (PPS) are added to an inter-layer reference picture set. Based on the indicator, the method can further include refraining from further signaling inter-layer reference picture information in any video slice associated with the at least one of the video parameter set (VPS), the sequence parameter set (SPS), or the picture parameter set (PPS). Alternatively, based on the indicator, the method can further include adding to the inter-layer reference picture set all direct reference layer pictures for any video slice associated with the at least one of the video parameter set (VPS), the sequence parameter set (SPS), or the picture parameter set (PPS).

Abstract: In one example, a device for coding video data includes a video coder configured to code an intra random access point (IRAP) picture of a partially aligned IRAP access unit of video data, and code data that indicates, when performing random access from the partially aligned IRAP access unit, at least one picture of a video coding layer that is not correctly decodable. When the video coder comprises a video decoder, the video decoder may skip decoding of the pictures that are not correctly decodable, assuming random access has been performed starting from the partially aligned IRAP access unit.

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 video coder stores only one derived disparity vector (DDV) for a slice of a current picture of the video data. The video coder uses the DDV for the slice in a Neighboring Block Based Disparity Vector (NBDV) derivation process to determine a disparity vector for a particular block. Furthermore, the video coder stores, as the DDV for the slice, the disparity vector for the particular block.

Abstract: When a current view is a dependent texture view, a current coding unit (CU) is not intra coded, and a partitioning mode of the current CU is equal to PART_2N×2N, a video coder obtains, from a bitstream that comprises an encoded representation of the video data, a weighting factor index for the current CU, wherein the current CU is in a picture belonging to a current view. When the current view is not a dependent texture view, or the current CU is intra coded, or the partitioning mode of the current CU is not equal to PART_2N×2N, the video decoder assumes that the weighting factor index is equal to a particular value that indicates that residual prediction is not applied with regard to the current CU.
