Mobile video delivery using network aware transcoding in an LTE network

Delivering video over mobile wireless networks presents several unique challenges. Limited bandwidth and packet delay variation can cause artifacts, "picture freezes," or blockages that make a video experience on a mobile client unacceptable. In this paper we address techniques to use feed...

Summary:Delivering video over mobile wireless networks presents several unique challenges. Limited bandwidth and packet delay variation can cause artifacts, "picture freezes," or blockages that make a video experience on a mobile client unacceptable. In this paper we address techniques to use feedback from the wireless network (congestion, channel conditions, content, user profiles) to adjust both the video stream and the delivery mechanism to dramatically increase the level of service and experience. We apply multiple control loops to realize these gains. © 2012 Alcatel-Lucent.
