Abstract: An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.

Abstract: Encoding and decoding architectures for 3D video delivery are described, such as 2D compatible 3D video delivery and frame compatible 3D video delivery. The architectures include pre-processing stages to pre-process the output of a base layer video encoder and/or decoder and input the pre-processed output into an enhancement layer video encoder and/or decoder of one or more enhancement layers. Multiplexing methods of how to combine the base and enhancement layer videos are also described.
