Abstract

Abstract

As the broadcasting networks have no feed back channel, the sender has no idea about the packets loss during the packets are transmitted. Signals may reduce and the Probability of Packet Loss (PPL) increases, when the terminals are on the edge of the cell or blocked by some buildings. A patching Forward Error Correction (pFEC) mechanism is proposed to provide low PPL in broadcasting networks. The mobile networks are used as the return channel to get the information of PPL, and the redundancy packets are transmitted via mobile networks for reducing the PPL. This mechanism provides the different packet loss recovery ability for different people according to the reports from receivers. The simulation results show that if the mobile networks are in a low PPL condition, the pFEC mechanism will have a good performance in decreasing the PPL, and improves the reliability and quality of service.
