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: In one example, a video coder, such as a video encoder or video decoder, is configured to code a video parameter set (VPS) for one or more layers of video data, wherein each of the one or more layers of video data refer to the VPS, and code the one or more layers of video data based at least in part on the VPS. The video coder may code the VPS for video data conforming to High-Efficiency Video Coding, Multiview Video Coding, Scalable Video Coding, or other video coding standards or extensions of video coding standards. The VPS may include data specifying parameters for corresponding sequences of video data within various different layers (e.g., views, quality layers, or the like). The parameters of the VPS may provide indications of how the corresponding video data is coded.

Abstract: Techniques are described for determining whether a block in a candidate reference picture is available. A video coder may determine a location of a co-located largest coding unit (CLCU) in the candidate reference picture, where the CLCU is co-located with a LCU in a current picture, and the LCU includes a current block that is to be inter-predicted. The video coder may determine whether a block in the candidate reference picture is available based on a location of the block in the candidate reference picture relative to the location of the CLCU. If the block in the candidate reference picture is unavailable, the video coder may derive a disparity vector for the current block from a block other than the block determined to be unavailable.

Abstract: A video coder determines a candidate for inclusion in a candidate list for a current prediction unit (PU). The candidate is based on motion parameters of a plurality of sub-PUs of the current PU. If a reference block corresponding to a sub-PU is not coded using motion compensated prediction, the video coder sets the motion parameters of the sub-PU to default motion parameters. For each respective sub-PU from the plurality of sub-PUs, if a reference block for the respective sub-PU is not coded using motion compensated prediction, the motion parameters of the respective sub-PU are not set in response to a subsequent determination that a reference block for any later sub-PU in an order is coded using motion compensated prediction.
