For example, Forward Error Correction (FEC) and Interleaving. Forward error correction (FEC) means it adds a redundant packet after the original packet, to increase the protection for packet loss. Interleaving mean it does a change for the order of packet, and because the order has been changed, so when the continuous packet loss occurs, not cause the clip of video loss. In this paper, we will use the combination of Forward Error Correction (FEC) and Interleaving method to calculate when the continuous packet loss occurs, we can accept how many packet loss. In this research, we also list the continuous packet loss occurs, the quantity for the missing, to do their corresponding measures of protection, in order to achieve optimal network transmission quality.
