4 10G unidirectional IP broadcast system
4.1 Overview
Cable TV network fiber-to-the-home 10G unidirectional IP broadcast system uses 1550nm wavelength to realize 10G IP data through optical power distribution
Stream broadcast transmission. As shown in Figure 1, the 10G unidirectional IP broadcast system is mainly composed of the IP broadcast front end, IP broadcast transmission network and IP broadcast receiving module.
Partial composition. Among them, the business data is transmitted step by step from the national level service platform to the prefecture and city service platforms.
After adding local service data as required, the data is broadcast to each user terminal through the optical transmission network in the format of a UDP multicast message.
End, here the UDP multicast format multicast address and UDP port number are used to distinguish different digital TV programs in the broadcast data. The specific group
See Appendix A for broadcast address planning. The 10 Gigabit unidirectional IP broadcast receiving module is usually located in the user access terminal system.
Broadcast UDP multicast packets, and select broadcast program streams based on their multicast addresses and port numbers.

Figure 1 Composition of 10 Gigabit unidirectional IP broadcast system
The 10 Gigabit unidirectional IP broadcast optical network can form a single unidirectional broadcast system and operate independently to carry out television broadcast services, as shown in Figure 2.
It can also work with two-way transmission systems (EPON/GPON, etc.) to build a 10 Gigabit broadband access network, that is, I-PON solution, which supports the TV live broadcast industry.
Services and two-way interactive video and high-speed data services (VOD video on demand, OTT TV Internet TV and Internet access, etc.), as shown in Figure 3
As shown. Refer to Appendix B for the network reconstruction plan of bidirectional networking. See Appendix C for examples of G/EPON bidirectional network convergence applications. I-PON Code
Type networking solutions include single-fiber three-wave networking and dual-fiber three-wave networking. For details, see GY/T 306.1-2017.
