Smoothing of video transmission rates for an LTE network

Video smoothing techniques can be used to facilitate more effective transmission and to preserve better video quality. In this paper we develop a semi-optimal video smoothing approach to manage the transmission rates of MPEG-4 and H.264 video over a QoS-based wireless LTE network. The proposed technique utilizes a smoothing buffer with pre-defined thresholds to smooth the transmission rates while assuming minimal information about the video to be transmitted. The results obtained showed a significant improvements in smoothing transmission rate variability. In addition, we show a model for the wireless LTE channel and use it as a feedback to manage smoothing and regulate and map the transmission rates based on the availability of network resources.
