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

In those example embodiments that make use of such predictions, the EL encoder (116) generates, based at least in part on the second multiplexed 3D image frame (108-V) and the prediction reference image frame, multiplexed 3D image residuals or differences between the prediction reference image frame and the second multiplexed 3D image frame 108-V and stores the image residuals in the enhancement layer video signal to be carried in the EL FC video stream (112-3). Further, based on the prediction and coding process, the RPU (114) may generate coding information which can be transmitted to a decoder as metadata using an RPU stream (112-2).

FIG. 1B illustrates a multi-layer video decoder (150) that receives input video signals in which high spatial frequency content from an original video sequence (which may be the input video sequence as discussed in connection with FIG. 1A) in two orthogonal directions has been preserved in complementary image data carried in the enhancement layer and in the base layer, respectively, in accordance with an embodiment. In an example embodiment, the input video signals are received in multiple layers (or multiple bitstreams). As used herein, the term “multi-layer” or “multiple layers” may refer to two or more bitstreams that carries input video signals having one or more logical dependency relationships between one another (of the input video signals).
