IRS systems are the most commonly installed systems within multi-dwelling commercial property developments where planning stipulates a limited number of aerials and dishes can be installed on the property. The IRS system is aimed at being a full digital reception system allowing residents to watch analogue and digital terrestrial television (Freeview), satellite channels (Sky digital) and it will also allow residents to receive FM and DAB (Digital Audio Band) radio.
The system utilises one digital aerial, FM directional and DAB aerial (on one rig) and a satellite dish to service any number of points. A head-end unit is installed to receive, process and combine the signals and then distributes the signal through a digitally screened coaxial cable network to an outlet plate, which then separates the signal back into TV, Satellite and Radio.
