1. Introduction to IRS
Around 7.5 million households in the British Isles now have digital reception
equipment. The proposed system to be installed will obtain digital signals
from the ASTRA satellite system that was originally launched in October
1998.
Because a significant percentage of households in the U.K. live in multiple
dwelling units and essentially run from communal systems then solutions
have to be found to ensure all residents can get access to digital. The
solution has to be found sooner rather than later because the Government
has announced that the 'old' analogue transmissions to houses will be
switched off perhaps as early as 2006. This could be delayed because of
the collapse of ITV digital because the vast majority of houses across
the country must have access to digital signals before analogue is switched
off.
Many existing properties are unable to receive Digital signals via a TV
aerial because the terrestrial transmitter from which they receive signals
does not transmit Digital.
The older communal systems that are installed and designed for analogue
signals are not able to distribute the enormous range of digital signals.
