IP Video service has a substantial growth on the internet in the last few years, and this gives a golden opportunity to popularize FTTH. As the hope of FTTH, EPON meets the bandwidth requirement of high quality video service. Using a point-to-multipoint topology, EPON is easy to set up channels for broadcast video. However, if the video stream isn't handled correctly, broadcast storm will occur on the attached link. So a novel scheme of multicasting IP Video over
EPON is presented in this paper to solve this problem. It not only guarantees validity of filtering video stream, but also guarantees QoS and security of this service. In the first part of this paper, the key technologies of multicasting IP video over EPON are introduced. Then FPGA implementation of this scheme is described in detail. Finally security of IP video is discussed.
