Abstract: In one example, a video coder is configured to code a first slice, wherein the first slice comprises one of a texture slice and a corresponding depth slice, wherein the first slice has a slice header comprising complete syntax elements representative of characteristics of the first slice. The video coder is further configured to determine common syntax elements for a second slice from the slice header of the first slice. The video coder is also configured to code the second slice after coding the first slice at least partially based on the determined common syntax elements, wherein the second slice comprises one of the texture slice and the depth slice that is not the first slice, wherein the second slice has a slice header comprising syntax elements representative of characteristics of the second slice, excluding values for syntax elements that are common to the first slice.

Abstract: In one example, a device for coding video data includes a video coder configured to code, for a bitstream, information representative of which of a plurality of video coding dimensions are enabled for the bitstream, and code values for each of the enabled video coding dimensions, without coding values for the video coding dimensions that are not enabled, in a network abstraction layer (NAL) unit header of a NAL unit comprising video data coded according to the values for each of the enabled video coding dimensions. In this manner, NAL unit headers may have variable lengths, while still providing information for scalable dimensions to which the NAL units correspond.

Abstract: This disclosure describes techniques for estimating a depth of image objects for a two-dimensional (2D) view of a video presentation. For example, an initial indication of depth (e.g., an optical flow) may be determined for a 2D view. The initial indication of depth may be used to estimate global motion, e.g., motion of an observer (e.g., camera), of the 2D view. The initial indication of depth may be modified based on the estimation of global motion to create a global motion-adjusted indication of depth. The global motion-adjusted depth indication may be used to create a depth map for the 2D view, which may be used to generate an alternative view of the video presentation that may be used to display a three-dimensional (3D) video presentation.

Abstract: A demultiplexer may assemble view components of sub-bitstreams. In one example, an apparatus comprises a demultiplexer that produces a multiview video coding (MVC) standard compliant bitstream from a received bitstream comprising a primary sub-bitstream and an embedded sub-bitstream. To produce the MVC standard compliant bitstream, the demultiplexer determines whether a view component of the primary sub-bitstream has a view order index that is greater than a view order index of a view component of the embedded sub-bitstream, and to add the view component from the sub-bitstream for which the view order index is lower to the produced bitstream. The received bitstream may comprise delimiter network abstraction layer (NAL) units between each view component to differentiate the view components. The apparatus may further comprise a video decoder to decode the bitstream produced by the demultiplexer.
