The DIGILINK magic eye system allows the viewer to control a Sky box from any room in the house which has a TV with a coaxial cable connection to the sky box. The DIGILINK is 100% compatible with the Sky, Sky+ & Sky HD. The Remote Eye is simply placed on top of the television set in the other room and relays remote control signals back to the main room. If you have a aerial signal supplied to your sky box, this signal will also be routed to your remote TV via the DIGILINK coaxial cable, this will allow you to watch freeview if built into your remote television. The magic eye system can be installed on a single remote TV or or on up to 8 other televisions within your property. Its a great way to add flexibility to your basic home sky & digital freeview system. Just use your main sky remote at the location of your other televisions to watch & control your main sky box. Additional sky remotes are now available from many local tesco supermarkets now, as well as many high street electrical outlets.
