Go to the store and look in the aisle for tv equipment. They have one, it would take me too long to find it on website to give you the exact name, but what it does is you plug it in one receiver box and plug the other one to the tv. It come with a remote, it is for HD signal, you can eliminate one receiver box! It goes through walls and floors! It is small enough that you can dangle it in the back of your tv, depending on the size of tv, the device is small and light! Unless you want to put it on a shelf. Hope this helps, I have been thinking of doing the same myself, so I know what you are asking!
