1. A three dimensional (3D) video encoder comprising:
a first encoder configured to encode a base view to form a first independently compressed video stream associated with video content; a second encoder configured to encode a nonbase view to form a second independently compressed video stream associated with the video content; a descriptor processor configured to generate a descriptor associated with at least one of the first independently compressed video stream and the second independently compressed video stream, wherein
the descriptor includes first information for use in combining a frame from the base view and a frame from the nonbase view in a same video sequence to render a 3D video, andthe descriptor includes second information corresponding to one of a picture level and slice level, the second information indicating at least one of an orientation of the base view, an orientation of the nonbase view, and an upsample rule, the second information being associated with a supplemental enhancement information message in which values represent picture size, base view picture size, Sample Aspect Ratio, number of legs in the re-sampling poly-phase filter in horizontal and vertical direction and number of filter coefficients; and a multiplexer configured to multiplex the first independently compressed video stream and the second independently compressed video stream and the descriptor to form a transport stream including the descriptor, the base view and the nonbase view. |
