MATV system
Radio
|
MATV systems normally provide reception of both analogue and digital
terrestrial television signals. The quality of reception of analogue television
varies with location. For best reception, there needs to be a clear
line of sight between the aerial and the transmitter. On some occasions,
hills or large buildings make it impossible to obtain a good picture. The
quality of digital is dependent on location. There are not enough
transmitters in the UK to provide full coverage and so, although we always
include digital in our proposals, there are locations where it is not
available.
Normally an MATV system would also distribute VHF FM radio and
this is received by a separate aerial. DAB can also be distributed
on a system and, like FM radio, needs its own aerial.

SMATV systems
|
SMATV systems (IRS) provide all of the programmes of an MATV system
plus satellite. The satellites received can be from just one orbital
position such as Astra at 28 degrees providing the Sky programmes, or
a number of positions which might include Eutelsat Hot Bird at 13
degrees.

systems

Apartment mini systems provide a repeat of all the programmes
available at the main point, including the output from the satellite decoder,
digital terrestrial decoder and VCR.
