IRS collects the broadcast signals from terrestrial (analogue & digital) and satellite transmitters, as well as FM radio and the new Digital Audio Broadcasts (DAB). All of these signals are then distributed via a single cable to a 3 socket wall outlet plate in the main rooms of the home, the cables are screened from electrical interference and the system can deliver all available TV channels to the resident, including both analogue and digital terrestrial, and digital satellite (with the addition of a minidish). IRS systems are equally suited to multiple dwelling units or single homes.
Installing IRS means that purchasers are free to decide to either connect their existing TV equipment to the system to pick up the existing analogue signals (until they are switched off), or to take up digital satellite or digital terrestrial television, now or in the future.
This solution means that the builder installing IRS does not have to favour any one particular supplier of TV programming. The choice is left to the customer.
