A study on the effect of MPE-FEC for 3D video broadcasting over DVB-H

Wireless networks are often error prone due to factors such as multi-path fading and interferences. In addition, the channel conditions of these networks are often non-stationary, such that the available bandwidth and channel error rates are changing over time with large variations. Therefore, they present a challenge for error-resilient video transmission. In order to maintain satisfactory QoS, a number of technologies have been proposed targeting different layers of the networks. DVB-H uses FEC for error protection and comes with an optional FEC tool (MPE-FEC) at the link-layer. In this paper, we propose to use the a priori knowledge of the transmitted media and apply MPE-FEC intelligently to provide better robustness by so-called Unequal Error Protection (UEP) mechanism. Extensive simulation results are given to show the effect of MPE-FEC on 3D compressed video under different channel conditions.
