A TV link (magic eye), links your SKY box to a TV in another room, so you can watch SKY in any room in the house!
Multi-link will link to as many TV’s as you like.
If you happen to have a standard box and a SKY plus box, both can be linked to all your TVs so that on each TV you will be able to view a SKY channel or a SKY plus channel (watch your recorded programmes in a different room)!
Basically you can have any combination of anything and don’t forget your free site survey!
