Is it possible to transmit a signal cable around a house?

I just got a house and you do not have a cable outlet in the room you want to see television. I really dont want to start drilling holes in the wall and feed the cables through walls, etc. Does anyone know of a transmitter cable, which sends the signal via radio waves to the TV. Basically I'm looking for a transmitter / receiver via radio waves for television cable. I know FM radio transmitters, but not for TVs. Any information would be appricatated! Thanks
