Use in Legacy Communal TV Systems
Existing communal integrated reception systems (IRS) often provide only one satellite feed to each household, preventing the use of dual-tuner DVRs. Upgrading the multiswitches and cabling to provide two or more feeds per household is usually both costly and invasive. However, individual households or sections of the system can be converted to SCR distribution so that multiple tuners within a household can be fed via the single existing coaxial cable.
Equipment such as Inverto’s Unicable Cascadable Switch can be connected to a conventional quattro LNB to provide a single SCR output and a conventional LNB output. The four IF inputs from the Quattro LNB are looped through to outputs so the unit can be cascaded to further SCR switches or to the existing multiswitches of the IRS, so an SCR-enabled output is provided without replacing the existing LNB or affecting the provision for conventional receivers in other households served by the rest of the system.
Versions of the Unicable Switch to provide for four and eight tuners within a household are available, and to combine a digital terrestrial signal onto the SCR-enabled output as well.
Global Invacom’s SCR Adaptor unit performs a similar function but is connected to the existing multiswitch outputs, to provide SCR compatibility for one connection (one household) of an existing IRS.
The SCR Adaptor connects to four outputs of an IRS multiswitch and provides a single SCR output that is typically connected to the existing single coaxial cable to the household to be converted. A further four conventional IF outputs are provided to recover usage of the existing multiswitch outputs for other households. Within the SCR enabled household, a splitter and power injector provides power to the SCR Adaptor and splits the signal to feed the separate tuners connected.
Global Invacom developed the SCR Adaptor in conjunction with BSkyB to enable flats and homes with single-feed distribution systems to fit Sky+ and Sky+ HD dual-tuner DVR receivers.

Famous quotes containing the words legacy, communal and/or systems:
“What is popularly called fame is nothing but an empty name and a legacy from paganism.”
—Desiderius Erasmus (c. 1466–1536)
“There is nothing in the world that I loathe more than group activity, that communal bath where the hairy and slippery mix in a multiplication of mediocrity.”
—Vladimir Nabokov (1899–1977)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
