Terrestrial
(MATV) systems normally provide reception of both analogue and digital
terrestrial television signals.
The
quality of reception of analogue television varies with location. best
reception, there needs to be a clear line of sight between the aerial and
the transmitter. some occasions, hills or large buildings make it
impossible to obtain a good picture. The quality of digital is dependent
on location. present there are not enough transmitters in the UK to
provide full coverage and so, although we always
s include digital in our proposals, there are locations where it is not
available.
Normally
terrestrial system would also distribute VHF FM radio and this is received
by a separate aerial. can also be distributed on a system and, like FM
radio, needs its own aerial.
SMATV
systems provide all of the programmes of an MATV system plus satellite.
The satellites can be from just one orbital position such as Astra at 28
degrees providing the Sky programmes, or other positions which might include
Eutelsat Hot Bird at 13 degrees.
Television
distribution systems normally provide each apartment with analogue
terrestrial television BBC1, BBC2, ITV, Channel 4, Channel 5, digital
terrestrial multiplexes 1-6 and usually FM BBC Radio
