Wireless TV link

[JeremyD]

I want to swap my two reception rooms round in a Victorian house. The TV aerial point is in the back room. I want to move the TV to the front room (solid wall between). I have a Humax Freeview set top box for that TV. I also have two small TVs in the childrens' bedrooms above the rear reception room.
Can I:
(a) get a wireless TV link that will 'send' non-digital terrestrial signals to ALL 3 TVs?
(b) But will it also send the digital terrestrial signals needed for the Humax Freeview box on top of the main TV in the front room?
Any suggestions on the best kit to buy, and where to buy it? (e.g. Currys, Argos, Maplin Electronics, eBay?
