USB Tuner and Freeview box too

You will probably need a freeview box. I'm not really sure how that all works because we don't have freeview in the United States. Assuming freeview boxes connect via HDMI, then you can use it on Xbox One. Otherwise you will need a freeview box and the Xbox
One Digital TV Tuner.

Enen, that's not a rumour, the Xbox One digital TV tuner is coming out in October and will cost 25 quid. It basically allows you to watch Freeview on the console, pause Live TV, use voice commands to change channels, works with DVB, DVB-2 and a 3rd one which
is DVB-C..? Anyways, you get your aerial lead and plug it into the tuner and then plug the USB bit into the Xbox One's many USB ports to be able to use the OneGuide. Should be able to use the Smartglass as an Xbox One media remote too.

The TV tuner is an alternative to a set top box which won't require you to use the HDMI in port.

@RippenHarra Freeview is not built into every television set here in the UK and it is most commonly a Box you have to buy seperately, we in the UK have just recently gone from terrestrial TV with a wopping 5 channels to having to have a digital tuner, the
reason it is a box is because we have a choice of different providers, Sky, Freeview, Youview, Freesat, it will however eventually end up as standard that TVs will have built in digital tuners but thats not the case at the moment.

If you've got an Aerial that goes into your HD, Freeview enabled telly, that should work with the X1 tuner, it's the same aerial that plugs into Freeview boxes.

It'll be good to play around with it and see if the channels look any better. It's currently coming out in the UK and a couple of European countries.

If you wish to run Freeview through your Xbox One, the solution is to buy an external Freeview tuner.
