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: Reference processing may be used in a video encoder or decoder to derive reference pictures that are better correlated with a source image to be encoded or decoded, which generally yields better coding efficiency. Methods for filter selection for a reference processing unit adapted for use in a video codec system are discussed. Specifically, methods for filter selection based on performing motion estimation and obtaining distortion/cost information by comparing reference pictures, either processed or non-processed, with the source image to be encoded are discussed.

Abstract: A method for adaptive streaming of video data over a network is disclosed. The method includes receiving, by one or more decoders of a video streaming client, first video information of a video data stream with one or more operations of first complexity. The method further includes obtaining client-related information based at least in part on a decoding capability of the video streaming client related to decoding the first video information with the one or more operations of the first complexity by the one or more decoders. The method also includes using, by the video streaming client, the client-related information to cause the video streaming from the video streaming server to the video streaming client to be adapted to a different overall bit rate and based at least in part on the client-related information.
