I stayed at a hotel once that sent their dish signal to all the tv's in the hotel, but they mapped their own channels and it did not require a box, not all the channels were there but they didnt send some of the channels to the tv's. How is it even possible to do this? Did they have some sort of special license to do this, would it be legal for me to do this. I could go with boxes but I don't want to have to pay for the extra wiring as it would probably cause a lot of money + I don't want to go back to cable just to get TV in all of my rooms.
