Abstract
The immense growth of mobile video traffic due to
significant user demand has sparked a great deal of
research on how to provide better-delivered video quality
through wireless networks. The mobile wireless network is
characterized by harsh transmission conditions in terms of
bandwidth limitation, device mobility, power constraints,
time varying and an error prone environment, resulting in
significant amount of loss and delay. It is challenging to
transmit and access multimedia data over wireless
communication channels. Some distortions may take place
in the video at the time of transmission or processing. Here
comes the need to evaluate the video delivered quality.
This paper addresses the problem of evaluating the quality
of video sequences encoded for and transmitted over Long
Term Evolution (LTE) mobile network. The LTEVidSim is
a MATLAB-based simulation tool-set for an evaluation of
the quality of video transmitted over a simulated LTE
network. It integrates the EvalVid and the Vienna LTE
System Level Simulator. In this study, we analyse some of
the thought-provoking research questions for video
streaming over LTE network, and explain by some
research examples how LTEVidSim can be applied.
