Abstract: A multi-layer video system has a first layer encoder that encodes a first layer of video information, at least one second layer encoder that encodes at least one second layer of video information, and an encoder side reference processing unit (RPU) that estimates one or more of an optimal filter or an optimal process that applies on a reference picture that is reconstructed from the first video information layer, and processes a current picture of the second video information layer, based on a correlation between the first layer reconstructed reference picture. The correlation relates to a complexity characteristic that scaleably corresponds to the first video information layer reconstructed reference picture and the second video information layer current picture. A scalable video bitstream is outputted, which may be decoded by a compatible decoder. A decoder side RPU and the encoder side RPU function as an RPU pair.

Abstract: Systems and methods for hierarchical motion estimation are described. The hierarchical motion estimation may provide motion information and pixel correlation among temporal pictures at different resolutions, which may be utilized in motion related video processing applications such as video coding, motion compensation based denoising, interpolation, and others to improve the quality and/or speed of motion predictions. Systems and methods of video processing that include pre- and post-processing utilizing information from hierarchical motion estimations are also discussed. Specifically, systems and methods of video processing with hierarchical motion estimation instead of or in addition to other motion estimations are shown.

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.
