AV around the house?

[prbaxter]

in my living room, i have VirginMedia V+ which goes to the telly. we have AV transmitters and receivers around the house which feeds the scart signal to our other CRT tellies.

Now, under our house is a deep void which you can walk around in (almost) so I can get right under the living room, and right under the kitchen.

If I fed the HD feed in to the cellar, could I junction it off somehow to the kitchen?

I'm basically wanting to cable the house up with HD cables so I can have HD tv's in most rooms, whcih will sace space, energy and will give a better quality picture.
