    摘要: Source and destination video devices may use data structures that signal details of an operation point for an MPEG-2 (Motion Picture Experts Group) System bitstream. In one example, an apparatus includes a multiplexer that constructs a data structure corresponding to a multiview video coding (MVC) operation point of an MPEG-2 (Motion Picture Experts Group) System standard bitstream, wherein the data structure signals a rendering capability value that describes a rendering capability to be satisfied by a receiving device to use the MVC operation point, a decoding capability value that describes a decoding capability to be satisfied by the receiving device to use the MVC operation point, and a bitrate value that describes a bitrate of the MVC operation point, and that includes the data structure as part of the bitstream, and an output interface that outputs the bitstream comprising the data structure.

    摘要: 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.

    摘要: In one example, an apparatus for signaling information for video data includes a processor configured to receive video data for two or more views of a scene, form a representation comprising a subset of the two or more views, and send, to a client device, as a part of a manifest of the representation, information indicative of a maximum number of views in the representation that can be targeted for output. An apparatus for receiving information for video data may receive the manifest including the information indicating the maximum number of views and request at least a portion of the video data of the representation based at least in part on a maximum number of views that can be output by the apparatus and the information indicative of the maximum number of views in the representation that can be targeted for output.

    摘要: A video coder performs a padding operation that processes a set of border pixels according to an order. The order starts at a bottom-left border pixel and proceeds through the border pixels sequentially to a top-right border pixel. When the padding operation processes an unavailable border pixel, the padding operation predicts a value of the unavailable border pixel based on a value of a border pixel previously processed by the padding operation. The video coder may generate an intra-predicted video block based on the border pixels.
