Real-time Internet Audio Using Optimal Forward Error Correction and TCP-friendly Congestion Control
Yufeng Shan · Mini-micro Systems · 2004
We introduce an unicast real-time audio transmission scheme over the Internet combining the Optimal FEC and TCP-friendly Congestion Control. We use TCP-friendly Congestion Control scheme to estimate the expected TCP-friendly sending rate for real-time audio flows. In the mean time, we use Optimal FEC scheme to decide how many redundant information should be included in the source packet and what kind of coding schemes should be chosen for the receiver to get the highest quality according to the network conditions and the TCP-friendly rate. Real experiments in the Internet and simulations in INRIA Sophia-Antipolis show that the scheme works well.
