IRS and SMATV TV Distribution

An IRS (Integrated Reception System) is a means of connecting multiple viewing points to a single common array of aerials and satellite dishes at a central point. At viewing points users have access to a wide range of TV and radio services. An IRS will typically provide for the reception of thousands of channels from one or more satellites, Freeview (digital terrestrial TV or DTT), DAB (Digital Audio Broadcasts) and FM radio. In addition it can also distribute locally generated analogue channels from studios, security cameras or DVD players etc.

The primary advantage of an IRS (Integrated Reception System) over other technologies for the distribution of TV is that it allows the individual user the freedom to access any Satellite, TV or radio channel received by the system antennae. Assess to thousands of channels and may be important for domestic users but in a business environment where only a selected range of channels are required, IPTV technology is considerably more cost effective and offers a host of advantages.

At the viewing point a TV receiver is connected to the system via a Freeview Set Top Box (STB) for the reception of Freeview and/or a satellite STB for reception of satellite channels. DAB and FM radio receivers are connected directly to the viewing point outlet. Locally generated channels are received directly through the TV aerial connector. To receive encrypted channels the appropriate STB and individual subscription smart card are required if necessary.

An SMATV (Satellite Master Antenna TV) system is designed to capture and decrypt (as necessary) a chosen selection of channels which are then combined onto a coaxial cable distribution system for viewing on a standard TV receiver at the outlets of the system. In practice the number of channels is limited for technical reasons to about 25 depending on several factors. It is possible to add Freeview channels to the system for access via a Freeview STB at the TV.
