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: A video base layer can contain information pertaining to frame-compatible interlace representations of multiple data categories while video enhancement layers can contain interlace or progressive representations and/or frame-compatible representations of these data categories. Video data are encoded and decoded using layered approaches.

Abstract: Rate control techniques are provided for encoding an input video sequence into a compressed coded bitstream with multiple coding passes. The final coding pass may comprise final splices with non-overlapping frames that do not extend into neighboring final splices. A final splice in the final coding pass may correspond to at least one non-final splice in a non-final coding pass. A non-final splice may have overlapping frames that extend into neighboring final splices in the final coding pass. The overlapping frames in the non-final splice may be used to derive complexity information about the neighboring final splices. The complexity information about the neighboring final splices, as derived from the overlapping frames, may be used to allocate or improve rate control related budgets in encoding the final splice into the compressed coded bitstream in the final coding pass.

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.
