Wireless Video Streaming Quality Management for Bandwidth Constrained Cellular Network

摘要

A method for wireless video streaming includes determining a backhaul bandwidth of a base station and ongoing traffic between a plurality of wireless clients and the base station, determining a video transcoding policy for each of the wireless clients based on a service agreement of each wireless client, decoding network signaling information, extracting a plurality of video streams based on the decoded network signaling information, and transcoding the plurality of video streams simultaneously upon determining that the ongoing traffic exceeds the backhaul bandwidth. Transcoding is based on a video transcoding policy of a receiving wireless client, video properties of a video stream being transcoded, and the decoded network signaling information.
