Problems about IPTV NGB EOC

For example, ngb is the next generation of radio and television technology; Mainly to achieve interactive on-demand mainly; Interactive VOD includes iptv and ipqam schemes;

Among them, iptv is to mix live channels with interactive on-demand computer rooms and transmit them through Ethernet; The main methods are fiber to the cell, then switch, and then twisted pair to the home;

In ipqam, the live channel and the on-demand content are transmitted separately, and then the on-demand content is transmitted to the community through optical fiber (that is, epon technology of olt+onu), and onu is responsible for converting optical signals into twisted-pair digital signals; Using the head end of eoc, the digital signal of two-pin cable is converted into the signal transmitted by coaxial cable. After mixing the on-demand content signal with the ordinary TV signal, the original ordinary TV signal line is transmitted to the user's home, and then an eoc terminal is connected to the set-top box, so that interactive on-demand TV can be realized and the Internet can be accessed at the same time! In terms of network, the last 100 meter usually refers to the distance from the user to the access layer switch; It should also be noted that eoc only refers to the transmission of Ethernet signals through coaxial cables; Nothing special, business, digital TV and broadband internet access can be carried out, all of which are the business of operators; I work in eoc, so I can communicate more when I have time!

As for what kind of eoc terminals to connect, there are many, including: Money Cat, Kyushu, Conte, Changhong, Ruikangda and so on! However, considering the compatibility problem, eoc is better to use the head end and terminal of the same manufacturer!
