Sky Q is the flagship brand from Sky and is not just a service, but a complete family of devices. It incorporates a number of enhanced elements over Sky+ boxes, while still providing many of the features you expect from the TV company.
There are a range of Sky Q hardware devices, starting with a top-of-the-range 2TB Sky Q set-top-box that’s the brains behind the outfit and designed to sit in the living room, much like the lesser- specced Sky+HD box. There is also a second main set-top-box, the Sky Q 1TB box, that has a smaller hard drive and lacks some features (such as Ultra HD support), but is a great alternative for those on a budget.
