MATV - IRS?

OK - my aged mum (almost 92 y.o.) is in a sheltered home run by Anchor
Trust, who have recently updated the TV distribution system by adding
a new outlet plate in her flat with an 'F'-type socket presenting
satellite TV service, but nobody has apparently been given any info
about it.
She isn't really worried about any changes as long as she can still
watch her 'usual' analogue-type stations, but to my mind it would be
nice if she could get some additional TV/radio stations. I have a
Panasonic Sky digibox lying about - would there be any point in
playing about with it to see if any satellite channels could be
received?
My experience of satellite stuff is that (probably analoguely) the
receiver actually tunes the LNB - obviously this is digitally
different...

As I said, she isn't concerned about any additional channels, but
would she be able to get any FTA services such as the BBC digi-only
ones?

You should be able to plug a Skybox into the wallplate and get some extra
channels. You might as well get an old Sky card or a Freesat card so she can
get C4 and C5 on it was well.

includes some information leaflets for residents. They are specific to
particular systems but you'll get some general idea re communal systems from
them.

By sister is also in an Anchor home and they can get either Satellite or
DTT. Ask the scheme manager *yourself* what is available, her scheme
manager is very good.

My experience of satellite stuff is that (probably analoguely) the
receiver actually tunes the LNB - obviously this is digitally
different...

The reciever doesn't so much as tune the LNB as select between one of 4
settings:

Horizontal High band;
Vertical High band;
Horizontal Low band;
Vertical Low band.

( In otherwords, the LNB is in 1 of 4 modes, it's not
continuously-variable. )

The high / low band switching is done by 22KHz tone.
The polarisation switching is done by voltage setting.

In a distribution system, rather than having one LNB per reciever ( that
would get out of hand rather quickly! ), a special Quadro LNB is used.
This is like a qual DNB, but each of the 4 LNBs is hard-wired to 1 of the 4
settings. These 4 signals between them carry all of the channels. They
are brought down to a Multiswitch device. This takes the 4 LNB outputs,
and distributes them to all the outlets. It is the multiswitch which
recieves the voltage / tone from each of the individual recievers, and the
multiswitch then sends the appropriate 1 of the 4 signal down to the outlet.
The reciever thinks it's talking to an LNB, it asks for the band /
polarisation, and the multiswitch supplies the goods.

Or something like that.
