IPTV is short for Internet Protokoll Television, that is Television via Internet. The TV-signal is transmitted through the LAN-outlet into every room. You can receive the signal with VLC, a browser interface or a Set-Top-Box.
In case you receive neither a signal nor an error message, it might be due to closed ports. Port 49151 must be open in your computer firewall in order to use IPTV. When using a WiFi-router, the same port must be opened there, as well. Furthermore, you must be within the dorm network, so deactivate any VPN- and Proxy-connections.
