摘要

A high resolution 3D image may be encoded into a first multiplexed image frame and a second multiplexed image frame in a base layer (BL) video signal and an enhancement layer (EL) video signal. The first multiplexed image frame may comprise horizontal high resolution image data for both eyes, while the second multiplexed image frame may comprise vertical high resolution image data for both eyes. Encoded symmetric-resolution image data for the 3D image may be distributed to a wide variety of devices for 3D image processing and rendering. A recipient device may reconstruct reduced resolution 3D image from one of the first multiplexed image frame or the second multiplexed image frame. A recipient device may also reconstruct high resolution 3D image by combining high resolution image data from both of the first multiplexed image frame and the second multiplexed image frame.

說明書

A 3D output image in the sequence of 3D output images as produced by the base layer video decoder (150-1) does not comprise full resolution 3D image data, as high spatial frequency content along one of the vertical and horizontal directions in the original video sequence that gives rise to the input video signals has been filtered/removed in the base layer video signal and cannot be recovered by the base-layer video decoder (150-1).

In an example embodiment, a BL decoder (152 of FIG. 1C) generates, based at least in part on the BL input video signal in BL FC video stream (112-1 of FIG. 1C), a multiplexed 3D image frame (e.g., 158-H of FIG. 1C). The BL decoder (152 of FIG. 1C) may be implemented using one or more of a plurality of codecs, such as H.264/AVC, VP8, VC-1, and/or others.
