Video delivery using network aware transcoding in an LTE network
"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 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.
