Unit recently distributing High Definition (HD) signals could be very tricky and expensive. It used to involve either running CAT5/6 cabling or HDMI cabling through the property using expensive matrix switches and converters.
Utilising Freeview HD televisions you can now distribute HD signals from any source using a Freeview HD modulator. This converts the HDMI signal (up to 1080p) to a Freeview HD COFDM signal that can be viewed on Freeview HD TV's.
The result is that you will see an additional channel on your Freeview HD TV, this can be named anything you want, for example Sky Box One, Sky Box Two, BlueRay etc.
