An Adaptive Video Transmission Algorithm to Improve Quality of Experience over LTE Access Networks

Abstract

The LTE standard is a promising solution to wireless connectivity. It promises high data rates at a low cost. At the same time, video traffic has so far outpaced other traffic types in growth, making it now the dominant traffic type in wireless networks. In this paper we study the concept of Quality of Experience for video traffic in LTE systems, Since video users are more annoyed by unpredictable packet loss, rather than reduced video fidelity, we developed an adaptive video coding scheme that aims to improve QoE in LTE networks, by continuously adapting the video fidelity, in order to keep the packet loss at acceptable levels.
