   An IRS mast (highest in picture) on a communal housing block, with a few of the aerials it will replace. An integrated reception system (IRS) provides broadcast signals from multiple sources (typically terrestrial television, FM radio, DAB digital radio and satellite TV) to multiple outlets, via a single aerial cluster and signal booster-distributor.

3. 8VSB - Wikipedia

   en.wikipedia.org/wiki/8VSB

   A modulation method specifies how the radio signal fluctuates to convey information. ATSC and DVB-T specify the modulation used for over-the-air digital television; by comparison, QAM is the modulation method used for cable. The specifications for a cable-ready television, then, might state that it supports 8VSB (for broadcast TV) and QAM (for ...

4. ATSC standards - Wikipedia

   en.wikipedia.org/wiki/ATSC_standards

   The ATSC signal is more susceptible to changes in radio propagation conditions than DVB-T and ISDB-T. It also lacks true hierarchical modulation , which would allow the SDTV part of an HDTV signal (or the audio portion of a television program) to be received uninterrupted even in fringe areas where signal strength is low.

5. Single-cable distribution - Wikipedia

   en.wikipedia.org/wiki/Single-cable_distribution

   A mixer in the dish-end equipment (an LNB or distribution unit) converts the received signal to the correct user band IF centre frequency for that receiver. [3] The converted transponders of the various users are then combined, and sent via the single coaxial cable to the receivers. The combined signal is tapped or split to reach every user.

6. SMATV - Wikipedia

   For maintaining a good signal-to-noise ratio at all the indoor units served, a larger antenna is required, typically 2 metres (6.6 ft) to 3 metres (9.8 ft) in diameter. A QPSK Digital Satellite Headend by Fracarro. A SMATV headend is used to receive and rebroadcast satellite television channels throughout a property from a single satellite feed ...

7. ATSC tuner - Wikipedia

   en.wikipedia.org/wiki/ATSC_tuner

   Canada had a similar analog TV termination date set to September 1, 2011 (except in some remote northern regions). [citation needed] It was feared that the US switch-off would cause millions of non-cable- and non-satellite-connected TV sets to "go dark". Viewers who did not upgrade, either to a television with a digital tuner or a set-top box ...
