My Home Theatre is still in the plannnig stage. One of the options I am looking as is to divert the audio and video signal to another room in the house. This room will have its own speakers, tv and receiver. The video signal I plan to move via a component cable, straight to the back of the tv in the other room. For the audio, i plan to run a Digital Coax cable to the other room to another reciever that will run the speakers. My question is, how far can you send these signals? Are we talking a few feet, a few meters or a few miles? In my case the component and coax cable will need to be about 30-40 feet (depending on the route that is taken when wiring it). If that distance proves to be too far for a standard signal from either of those cables, is there a way to boost them?
