Signaling characteristics of an MVC operation point

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.

1. A method comprising:
constructing, with a source device, one or more operation point descriptors each corresponding to respective multiview video coding (MVC) operation points of an MPEG-2 (Motion Picture Experts Group) System standard bitstream, wherein each operation point descriptor is separate from network abstraction layer (NAL) units included in the MPEG-2 System standard bitstream, wherein each operation point descriptor signals a rendering capability value that describes a rendering capability to be satisfied by a receiving device to use the MVC operation point and a decoding capability value that describes a decoding capability to be satisfied by the receiving device to use the MVC operation point, wherein each operation point descriptor is included as part of the bitstream, and wherein constructing each operation point descriptor comprises:
including a temporal-identifier value in the operation point descriptor that corresponds to a frame rate for a video stream assembled from the video data of the views for the MVC operation point;including values in the operation point descriptor representative of views targeted for rendering of the MVC operation point; andincluding values in the operation point descriptor representative of views to be decoded for the MVC operation point; and outputting the bitstream comprising the operation point descriptors that correspond to the respective MVC operation points.
