Paper Abstract

There are two primary methods of transmitting signal of digital television to the home in China. The first one is HFC mode, which is widely used. The other is IPTV mode, which is emerging. In this paper, the scheme of digital television over Ethernet PON is proposed. There are several differences from this system to IPTV and Video over LAN: the real-time transmission of equal-bandwidth based on statistical multiplexing, channel switching based on multicast and IP CA system, etc.. And these are also the key techniques used in this system. The architecture of DTV over EPON system, the function of every component, the framing process and the multiplexing of Ethernet frame are described. The implementation procedure of the system is shown. The mechanism of channel switching using multicast technique is designed and realized. We also present the method of using static VLAN and IGMP snooping mechanism to implement statistical multiplexing on Ethernet layer, and put forward the concept of IP Conditional Access System and define it. An experimental system of DTV over EPON is set up and the experimental result is significant.
