SMATV (Satellite Master Antenna Television), CATV (Cable Television), and IPTV (IP Television) all explain different technologies to provide a TV distribution system within a building, interconnecting multiple television sets to a single source (usually called Head End) so each television can select the desired watching channel from a selection list.
An integrated reception system (IRS) provides broadcast signals from multiple sources (typically terrestrial television, FM Radio, DAB digital radio and satellite T) to multiple outlets, via a single aerial cluster and signal booster-distributor.
