The textbook definitions
- IPTV (internet protocol television), in the strict sense, is TV delivered over a managed network controlled by the operator, typically a broadband provider sending TV to its own set-top boxes, with quality guaranteed end to end.
- OTT (over-the-top) is video sent over the open internet, “over the top” of whatever broadband you have. Netflix, iPlayer and YouTube are OTT.
Why the terms blur
In everyday UK use, “IPTV” has come to mean live TV channels delivered over the internet to player apps, which is technically OTT. People say “IPTV” for live channel subscriptions and “streaming” for on-demand apps, but the delivery technology is largely the same.
| Managed IPTV (strict) | OTT | |
|---|---|---|
| Network | Operator’s own network | Public internet |
| Devices | Operator’s box | Any compatible device or app |
| Quality control | End to end | Best effort, adaptive |
| Example | Operator TV boxes on its own broadband | Netflix, iPlayer, IPTV player apps |
What it means for you
Because most services, including ours, are delivered over the open internet, your home connection matters. A stable broadband line, good Wi-Fi or a wired connection and a capable device make the biggest difference. See buffering fixes, and how delivery works behind the scenes in how IPTV servers work.
