Abstract: For a depth block in a depth view component, a video coder derives a motion information candidate that comprises motion information of a corresponding texture block in a decoded texture view component, adds the motion information candidate to a candidate list for use in a motion vector prediction operation, and codes the current block based on a candidate in the candidate list.

Abstract: In general, the disclosure describes techniques for coding depth blocks in video data. A video coding device may determine a size of a sub-prediction unit (sub-PU) for motion parameter inheritance (MPI) in a depth prediction unit (depth PU). The depth PU may comprise one or more sub-PUs, each sub-PU having equal size. Distinct motion information can be inherited for each sub-PU from a texture block co-located to the sub-PU. The device may encode each sub-PU based on MPI corresponding to texture blocks co-located with the sub-PUs and generate a syntax element that indicates the size of each sub-PU for MPI. The device may further receive the syntax element, and, upon receiving an index value that indicates a sub-PU MPI mode, inherit MPI for each sub-PU based on the corresponding texture blocks.

Abstract: A method of coding video data includes deriving prediction weights for illumination compensation of luma samples of a video block partition once for the video block partition such that the video block partition has a common set of prediction weights for performing illumination compensation of the luma samples regardless of a transform size for the video block partition, calculating a predicted block for the video block partition using the prediction weights using illumination compensation, and coding the video block partition using the predicted block.

Abstract: An apparatus configured to code video information includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with an enhancement layer having a first block and a base layer having a second block, the second block in the base layer corresponding to the first block in the enhancement layer. The processor is configured to predict, by inter layer prediction, the first block in the enhancement layer based on information derived from the second block in the base layer. At least a portion of the second block is located outside of a reference region of the base layer, the reference region being available for use for the inter layer prediction of the first block. The processor may encode or decode the video information.

Abstract: A device for coding three-dimensional includes a video coder configured to add one or more motion vector candidates to a motion vector candidate list; identify, from the one or more motion vector candidates in the motion vector candidate list, a disparity motion vector candidate; based on the disparity motion vector candidate, determine a disparity shifted motion vector (DSMV) candidate; and add the DSMV candidate to the motion vector candidate list; and code the block of video data using a motion vector corresponding to the identified candidate.

Abstract: A computing device generates a file that comprises a track box that contains metadata for a track in the file. Media data for the track comprises a sequence of samples, each of the samples being a video access unit of multi-layer video data. As part of generating the file, the computing device generates, in the file, a sub-sample information box that contains flags that specify a type of sub-sample information given in the sub-sample information box. When the flags have a particular value, a sub-sample corresponding to the sub-sample information box contains exactly one coded picture and zero or more non-Video Coding Layer (VCL) Network Abstraction Layer (NAL) units associated with the coded picture.

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.

Abstract: A video processing device can be configured to process one or more initial syntax elements for a parameter set associated with a video bitstream; receive in the parameter set an offset syntax element for the parameter set that identifies syntax elements to be skipped within the parameter set; and based on the offset syntax element, skip the syntax elements within the parameter set and process one or more additional syntax elements in the parameter set that are after the skipped syntax elements in the parameter set.
