A Performance Evaluation of H.264 FGS Sequences over Hybrid Networks

In this article, we study the performance of transmitting H.264 video sequences over hybrid networks formed by a collection of wired and wireless links. We use the Gilbert-Elliott error model to simulate the wireless transmission channel. Taking the effects of fading into consideration, our numerical results show that the quality of the reconstructed video sequences is seriously degraded. We then investigate how the addition of FEC techniques like the Reed-Solomon codes and the use of MIMO techniques help improve the performance of wireless links and consequently the quality of reconstructed video transmitted over such links.
