Abstract: 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.
