What is IPTV and how does it work in the UK?
What IPTV actually means, how it differs from Freeview and satellite, and what you need to run it on a standard UK broadband connection.

Almost every IPTV plan allows more than one simultaneous connection, but what that actually means in practice gets misunderstood a lot. It is not "one user per device the app is installed on"; it is a limit on how many connections can be actively streaming at the same time under the same credentials. You can install the app on the living room TV, the bedroom TV and a tablet with no issue at all, the limit only matters once several of those devices try to play something at once.
Usually one of the two streams freezes or drops until the other device stops playing. There is rarely a clear on-screen warning, so if playback stalls right when someone else in the house turns their TV on, that is the typical symptom of hitting the plan's simultaneous connection cap, and it is worth telling apart from a genuine network problem, which is covered in detail in the guide on how to fix IPTV buffering.
Yes, as long as the plan supports it: each simultaneous connection is independent and can be tuned to any channel or piece of content in the catalogue, it does not need to match what the other screens are watching. That is the main difference from traditional aerial or satellite TV, where every set in the house receives the same feed unless there is a separate receiver for each one.
Using the same server URL, username and password across several devices in your own household is exactly what the plan's simultaneous connection limit is designed for. What does not work well is handing those same credentials to people outside the home: once the contracted number of connections is exceeded, everyone starts experiencing dropouts for no obvious reason, and that is usually harder to diagnose than a simple Wi-Fi issue.
It depends on how many people in the house might want to watch different things at the same time, not on how many TVs you own. A household of four with a living room and two bedrooms typically needs two to three simultaneous connections as a reasonable margin, though it is worth checking against your own household's habits before picking a plan, as covered on the pricing page.
For a technical reference on how multi-user streaming shares bandwidth on a home network, the FCC broadband speed guide is a solid starting point for working out whether your connection can support several active screens at once.
