What Is IPTV and How Does It Work? A Plain-English Guide
⚡ Quick Answer
IPTV explained without the jargon: how TV over broadband works, what you need at home, and how it compares with Sky, Freeview and streaming apps.
IPTV in one sentence
IPTV (Internet Protocol Television) is live TV delivered over your broadband instead of through an aerial, satellite dish or cable.
You probably already use it
BBC iPlayer's live channels, Sky Glass and the live TV on most streaming apps are all forms of IPTV. An IPTV subscription simply brings many live channels, sport and on-demand films together in one app.
How it works at home
- Your provider streams channels from its servers over the internet.
- Your broadband carries the stream to your home.
- An app on your Firestick, Smart TV or phone plays it, with a TV guide on top.
What you need
- Broadband: around 15 Mbps per screen for HD.
- A device: a Fire TV Stick, a Smart TV, an Android box, a phone or a computer.
- An app and a login: we provide both.
How it compares
- Versus Sky or Virgin: no dish, no box to rent, no long contract. See IPTV vs cable and satellite.
- Versus Freeview: far more channels, plus sport and films, and catch-up across channels.
- Versus Netflix-style apps: live TV and live sport as well as on-demand.

The journey of a TV channel
- Source: the provider receives a channel's broadcast feed.
- Encoding: the feed is compressed so it can travel efficiently over the internet.
- Servers: copies of the stream are made available on servers.
- Delivery: when you press play, your device requests the stream and it travels over the internet to your home.
- Playback: your app decodes it and shows it on screen with the TV guide.
Why quality can change
Most IPTV streams use adaptive bitrate: if your connection dips, the stream briefly drops to a lower quality instead of freezing. That is why a picture may look soft for a moment and then sharpen.
Live TV, catch-up and on demand
- Live: channels as they are broadcast.
- Catch-up: recently broadcast programmes stored for a few days.
- On demand: a library of films and series you can start any time.
Logins: M3U and Xtream Codes
Providers give you either a single M3U link or Xtream Codes (server, username and password). Most apps accept both. Our own app avoids both — you just sign in. See M3U vs Xtream Codes.
IPTV and your broadband
Because everything comes over the internet, a steady connection matters more than a fast headline speed. A wired connection to the TV makes the biggest difference. Read how to stop buffering.
