NBG-460N User’s Guide

Internet Protocol Television (IPTV) is a service with which you can subscribe in 
order to watch video content hosted on servers over the Internet in your television 
at home. An IPTV subscription gives you access to streaming media, such as Live 
TV or Video on Demand (VOD). 

The NBG-460N has four LAN ports. You can assign up to two of these LAN ports as 
the IPTV STB port/s where you connect your Set-Top Box (STB). See 

. A Set-Top Box (STB) enables you to watch Live TV and/or VOD from 

the Internet directly on your television screen. 

Note: You can connect an STB to a LAN port if the video streaming format is IGMP-v1 

or IGMP-v2. If your video streaming uses a different format, then convert the 
LAN port to an IPTV port and then connect the STB to it.

To understand the IPTV STB port, you need to understand the concepts of LAN 
and WAN. 

In the rear panel of your NBG-460N, you can see four LAN ports (LAN 1 to LAN 4) 
and one WAN port as in the figure below.

Figure 96   Rear view of NBG-460N

The WAN port is for your Internet access connection and has a different IP address 
from the LAN ports. The LAN ports are for computers, printers and other network 
devices in your home. The LAN ports share the same IP address. 

These scenarios should help you decide whether to choose to convert one or two 
ports.

Note: You should have an IPTV subscription to avail of video services over the 

Internet.
