What Is IPTV? A Complete Beginner's Guide
Internet Protocol Television explained from first principles: what it is, the different kinds you'll meet in the UK, and what you need to get started.
ReadAerial, dish, cable or broadband? An even-handed comparison of how UK households can receive television today.
Traditional television is broadcast one-to-many over radio, satellite or cable, so everyone receives the same signal at the same moment. IPTV sends programmes as data over an IP network, which enables on-demand viewing, catch-up and viewing on any connected device, but makes picture quality dependent on your broadband and home network.
The UK industry is steadily shifting towards internet delivery: Freely brings live channels to compatible TVs over broadband, and pay-TV operators now offer dish-free, broadband-only TV packages.
| Factor | Broadcast (aerial/satellite/cable) | IPTV |
|---|---|---|
| Installation | Aerial, dish or cable connection | Broadband connection only |
| Reliability | Very consistent once installed; weather can affect satellite | Depends on broadband and home network |
| Latency | Lowest — the live reference | Typically several seconds behind |
| Rooms and devices | Needs a tuner or box per TV | Any compatible screen on the network |
| On-demand and catch-up | Limited without a connected box | Built in |
| Picture quality | Fixed by broadcaster | Adaptive; up to 4K where offered |
You have weak or unreliable broadband, watch mostly live TV on one main set, or want the lowest possible delay for live events.
You watch across several rooms or devices, rely on catch-up and on-demand, live in a flat where dishes aren't allowed, or simply want one interface for everything.
Many homes keep an aerial for live channels and use IPTV for everything else. Most smart TVs support both at once.
Whatever the delivery method, a TV Licence is required to watch or record live TV or to use BBC iPlayer. Beyond that, compare the cost of the content services you actually want, plus any software and equipment. Be sceptical of any IPTV offer that bundles hundreds of premium channels for a fraction of their usual price — legitimate rights are expensive, and unlicensed services put viewers' data and devices at risk.

It can be. Freeview HD channels are broadcast at a fixed quality, while IPTV services can offer higher bitrates and 4K. On a weak connection, however, IPTV adapts downwards.
There is no fixed switch-off date. Terrestrial TV is secured until at least 2034, and the industry continues to debate its long-term future.
Yes. Most smart TVs have a built-in Freeview tuner and can also run IPTV apps, so you can switch between them.
