When they provide Internet Protocol Television (IPTV) services,IP networks face difficulties such as reduced transmission bandwidth,delay,jitter,and packet loss.A terminal-centric solution can improve the image quality by adding control policies like congestion control and error control to the receiving terminal and source code.An end-to-end application layer reliability method is usually required to satisfy IPTV requirements in the IP network.Application Layer Forward Error Correction (AL-FEC) technology solves the problem of packet loss,and can ensure the end-to-end reliability for IPTV services.
