Hi, I am getting a new house and I will be mounting the tv on the wall, behind the wall is a room where I will have all the components. I saw a friend have the same kind of setup but not sure what it was. I know on his tv he had a little black circle that I assume he pointed some remote at to turn everything on. What do I need to accomplish this please. Not looking to spend hundreds on this but I would like to know how to accomplish this and what I need please.
Thanks
