How does IPTV actually work?
With traditional TV, a broadcaster sends every channel to your home at once through a cable or satellite signal, and your box tunes into one of them. IPTV works the other way around: when you choose a channel, your device requests just that stream over the internet, and the server sends it back in real time. It is the same on-demand principle as Netflix or YouTube, applied to live TV as well as films.
In practice that means there is no dish and no coaxial wiring. Your Smart TV, Firestick, box, phone or computer runs a small player app that connects to the service, loads the channel list and the TV guide (EPG), and plays whatever you select. Because it is just data over your existing connection, you can watch in another room, on a second device, or even away from home.
