Terrestrial Switchoff - sorry to labour the point but...

For those who haven't yet seen the Ofcom consultation on future mobile
broadband spectrum.

"The 694-790 MHz band is expected to become a key band for mobile
broadband"

and references to studies at 470 - 694 MHz.

If they switch off terrestrial TV, that means that the only ways to receive
TV will be:

- satellite
- cable
- internet (ASDL or mobile)

Cable and Internet charge subscription fees and, in the case of Internet,
data usage fees once you get beyond an agreed level. Cable is only available
in certain areas (mainly urban).

Satellite requires you to have a dish and limits you to a fixed number of
receivers, in that each receiver (TV, hard disc recorder etc) that wants to
tune to a different channel needs a separate LNB at the dish, because
satellite dishes unlike TV aerials don't supply the full spectrum of
multiplexes simultaneously to the receiver.

None of these are suitable for people who are mobile (canal boats, caravans)
in areas of sparse population where there is no mobile coverage.

Plenty of caravans, canal boats etc. with satellite dishes.

Really? How long does it take from arriving/mooring to being able to point
the dish in the correct direction? And for boats, how precise does the
alignment have to be, given that boats may drift or bob on their moorings?

I only ask because even when we had satellite fitted at our house, it took
the installer a long time to line the dish up correctly after he'd fitted it
and the cables: he was up and down the ladder, tweaking it, for ages. It
doesn't help that dishes are usually fitted so low down (not at chimney
level) so they can't always see over neighbours' roofs.

Yes really.

I think Dickie Mint has answered this much better than I could.

Hmm, maybe a problem with your installer. ;-)

There is no theoretical limit to the number of satellite receivers. A
box called a Multiswitch can feed many receivers from one 4-way LNB.
http://en.wikipedia.org/wiki/Multiswitch

I have three Freesat boxes. Two are recorders with two tuners each and
the third is a single tuner non-recording box. They are fed from an
8-output multiswitch that has input from a 4-way LNB. That means there
are 3 spare outputs. All the outputs from the multiswitch are
independent of one another.

One seller's website:
http://www.satellitesuperstore.com/multiswitch.htm

I understand that some multiswitches can be cascaded.

None of these are suitable for people who are mobile (canal boats, caravans)
in areas of sparse population where there is no mobile coverage.

It is possible to get around this. e.g. use a system like those that put
the outputs from all four onto one optical fibre for distribution around
the home, and have suitable optical receivers for each 'TV' or 'recorder'.
Or do something similar via a computer with a set of tuners feeding 'TVs'
via ethernet. *BUT* this of course all adds to the costs and the work
needed for a home install that is sufficient to avoid more work when
someone wants to add another 'TV' to the home. So not exactly the "poor
man's solution" to loss of DTTV!

The basic problem here is that from a technical / engineering POV all the
problems of losing DTTV access are solvable - if price is no object. BUT in
reality, and in the timescale of the next 2-5 years, for many people the
cost or inconvenience would be high.

So the recent decison and the proposals to go further seem to be based on
applying the H2G2 attitude. "Today is a golden age where no-one will be
unable to access TV if DTTV is removed... well, no-one worth mentioning,
anyway!" I don't see 50 quid and a free filter fixing this.

Slainte,

Jim

Well eventually they will get rid of terrestrial I suspect, but maybe they
will keep one channel for emergencies or something.
The real snag with using sats as has been said is that its very much a
fixed receiver thing. I know some ocean liners have it but not your average
trawler!

also, though, if the delivery is via radio waves from a mobile broadband
system, that may well be made cheaper and hence as viable a as the current
freeview.
Who knows. If the sun cuts up rough in the next few years and trashes the
sats, then what.

I doubt it will occur till about 7 to ten years down the line though, as
lots of manufacturers want to sell their kit and if people think this is
going to happen they will not sell it will they?
