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 first descriptor describes an operation point. The second descriptor is a hierarchy descriptor or a hierarchy extension descriptor. The second descriptor has a hierarchy layer index value equal to a value of the second syntax element. A first value of a first syntax element in the first descriptor specifies that an elementary stream indicated by a second syntax element in the first descriptor, when not present in an elementary stream list, shall be added into the list, and an elementary stream indicated by an index in the second descriptor, when not present in the list, shall be added to the list. Responsive to determining the first syntax element has a second value different from the first value, adding the elementary stream indicated by the second syntax element, when not present in the list, into the list, but not the elementary stream indicated by the index in the second descriptor.

Abstract: A video encoder generates, based on a reference picture set of a current view component, a reference picture list for the current view component. The reference picture set includes an inter-view reference picture set. The video encoder encodes the current view component based at least in part on one or more reference pictures in the reference picture list. In addition, the video encoder generates a bitstream that includes syntax elements indicating the reference picture set of the current view component. A video decoder parses, from the bitstream, syntax elements indicating the reference picture set of the current view component. The video decoder generates, based on the reference picture set, the reference picture list for the current view component. In addition, the video decoder decodes at least a portion of the current view component based on one or more reference pictures in the reference picture list.

Abstract: A first reference index value indicates a position, within a reference picture list associated with a current prediction unit (PU) of a current picture, of a first reference picture. A reference index of a co-located PU of a co-located picture indicates a position, within a reference picture list associated with the co-located PU of the co-located picture, of a second reference picture. When the first reference picture and the second reference picture belong to different reference picture types, a video coder sets a reference index of a temporal merging candidate to a second reference index value. The second reference index value is different than the first reference index value.

Abstract: A video coder codes a slice header for a slice of video data. The slice header includes a syntax element comprising identifying information for a long term reference picture, wherein the identifying information is explicitly signaled in the slice header or derived from a sequence parameter set corresponding to the slice. When the syntax element indicates that the identifying information for the long term reference picture is explicitly signaled, to code the slice header, the video coder is further configured to code a value for the identifying information for the long term reference picture in the slice header.

Abstract: A video decoder assembles, in a buffer model, an access unit from a plurality of elementary streams of a video data stream. The video data stream may be a transport stream or a program stream. The same buffer model is used regardless of whether the elementary streams contain Scalable High Efficiency Video Coding (SHVC), Multi-View HEVC (MV-HEVC), or 3D-HEVC bitstreams. Furthermore, the video decoder decodes the access unit.
