Abstract: A parent block is partitioned into the plurality of blocks and a disparity vector derivation process is performed to derive a disparity vector for a representative block in the plurality of blocks. A video encoder generates a bitstream that includes a coded representation of the video data in part by performing, based on the derived disparity vector and without separately deriving disparity vectors for any block in the plurality of blocks other than the representative block, inter-view prediction for two or more blocks in the plurality of blocks. A video decoder reconstructs sample blocks for two or more blocks in the plurality of blocks in part by performing, based on the derived disparity vector and without separately deriving disparity vectors for any block in the plurality of blocks other than the representative block, inter-view prediction for the two or more blocks in the plurality of blocks.

Abstract: A method of coding video data includes receiving video information associated with a first layer and a second layer and determining whether at least one of the first layer and the second layer is a default layer. The method can include at least partially restricting inter-layer prediction when neither the first layer nor the second layer is the default layer. A default layer can be a base layer or an enhancement layer. A flag can be received that indicates that inter-layer prediction is to be restricted. In addition, the method can include determining whether inter-layer prediction is allowed for the video information associated with the first layer, and determining whether inter-layer prediction is partially allowed for the video information associated with the second layer such that motion compensation is not used with the second layer video information.

Abstract: In an example, a video coder may determine a first layer component of a first layer of video data, wherein the first layer of video data is associated with a layer identifier. The video coder may generate at least one filtered layer component by filtering the first layer component, and assign the layer identifier of the first layer and a filtered layer component index to the at least one filtered layer component, where the filtered layer component index is different than a layer component index of the first layer component. The video coder may also add the at least one filtered layer component to a reference picture set for performing inter-layer prediction of a layer other than the first layer of video data.

Abstract: Techniques are described for modal sub-bitstream extraction. For example, a network entity may select a sub-bitstream extraction mode from a plurality of sub-bitstream extraction modes. Each sub-bitstream extraction mode may define a particular manner in which to extract coded pictures from views or layers to allow a video decoder to decode target output views or layers for display. In this manner, the network entity may adaptively select the appropriate sub-bitstream extraction technique, rather than a rigid, fixed sub-bitstream extraction technique.

Abstract: When coding multiview video data, a video encoder and video decoder may select a candidate picture from one of one or more random access point view component (RAPVC) pictures and one or more pictures having a lowest temporal identification value. The video encoder and video decoder may determine whether a block in the selected candidate picture is inter-predicted with a disparity motion vector and determine a disparity vector for a current block of a current picture based on the disparity motion vector. The video encoder and video decoder may inter-prediction encode or decode, respectively, the current block based on the determined disparity vector.
