Controllable multicast for IPTV over EPON

The character of 1 Gbps bandwidth and treebased structure make Ethernet passive optical network (EPON) very suitable for broadcast or multicast services such as Internet protocol television video (IPTV). The document proposed a novel scheme, based on the former research for controllable multicast over EPON system, mainly considering system security and maintainability. It can both control the IPTV program source’s and the receiver’s validity, improving the efficiency and precision.
