Abstract
Degradation control management is provided for a plurality of video streams associated with a plurality of user terminals in a communication network, based at least in part on an overall video quality metric, by determining a video quality metric for each video stream based on at least a set of video quality metric input parameters, and calculating an overall video quality metric based on the determined video quality metrics for the video streams, determining, with an objective function, at least one objective parameter based on at least the overall video quality metric, calculating a scheduling parameter for each video stream using a degradation control algorithm based on at least the determined video quality metric for the respective video stream and on the at least one objective parameter, and scheduling network resources for each video stream based on at least the scheduling parameter for the video stream.
