We have a 'Loftbox'. This is a neat device.
This is how is works.....
You run a Cable from the Loftbox to your Main TV Point/Sky Box and one back up into the loft. You then feed all your additional 'Inputs' into it, such as Terrestrial TV, Sky, DAB, FM Radio, CCTV etc.
You can get a 4-way or 8-way Loftbox. This then has 4 or 8 outputs that go to up to 8 TV's. Any of the TV's can watch whatever is connected to it (Sky/TV/Radio etc etc). It has a built-in amplifier too.
We also have a 'Magic Eye'. This allows you to control your Sky Box from any room. It is a device that plugs into the TV Aeriel Socket and has an IR Sensor on the front. You then use a normal Sky remote to alter the channel in any room.
The result is that we can watch Sky/Normal TV etc in any room of the house (that has a TV). OK, so we can't watch independant channels, but you can't have it all!!
