What is the tvLINK?
The tvLINK, also known as the Magic Eye was a very clever accessory that Sky marketed shortly after the launch of Sky Digital.
The tvLINK allowed users to watch the same Sky digital programme across multiple televisions. A typical tvLINK package would include everything you needed to get started with it (apart from coaxial cable), and would typically include a secondary remote control too.
The tvLINK utilised the RF2 output, which could provide a 9V power supply to the tvLINK device to allow control. The settings to access this were contained within the 'Installer Setup'.
