MULTI-LAYERED VIDEO STREAMING SYSTEMS AND METHODS

Abstract:

Systems and methods for enabling a video capture/encoding device to capture frames of a video sequence; obtain feedback from a video decoding/rendering device; divide each frame into an array of patches; select one or more patches of each frame for supplemental processing; cause the frames of the video sequence to be encoded by a video encoding module and cause the selected patches to be processed by one or more supplemental processing module(s); and assemble a multi-layer video transport stream wherein, for each frame of the video sequence, a base layer of the transport stream includes data corresponding to an encoded version of the current frame and one or more supplemental layers of the transport stream include meta-data corresponding to the division of the current frame into patches and data corresponding to the output of the supplemental processing of the selected patches of the current frame.
