I have 5 TV's throughout the house that I use. Since I only use one at a time, I would like to use my digital cable box to feed them all. This part is not a problem. The problem is trying to control the box with the IR remote when it is located in a different room. I have build IR repeater circuits in the past using a dedicated wire. Has anyone used the existing coax within the house to carry the repeated signal back to the equipment to be controlled? Is this possible without interferring with the cable signal? Is there another way to do this that would be easier and cheaper short of re-wiring the house?
