What will happen at analogue switch-off?

Presumably the UHF tuners on TV sets will gradually disappear also as
they won't be needed any more for receiving broadcasts, so linking
devices by UHF will become a thing of the past anyway.

If the analogue tuners do disappear then distribution systems around
houses ie for VCR, SAT, will need something more expensive than now
Maybe the system will get replaced with digital, ie digital tuner, the
only snag is you'll need a COFDM modulator and upconvertor, which in time
will get cheaper.
It's DVB-S that amateurs seem to be going for.
The unit in question is probably this:

Cost is about £500.

Would that help?

Thinking about my own TVs at home and lack of STBs on all 5 of them
(eek!),
got me to wondering what will happen at the big analogue switch-off...

Other than the obvious, what will hapen - specifically to the DVB
broadcasts
in terms of power and capacity?
I heard that the signal power will be increased. I sthat true?
Also, will there eventually be new MUXes when the transmitters are not
busy
transmitting analogue signals too, making space for more channels and the
ability to improve bitrates on the existing ones?


I suppose we could have the existing 5 channels turned into digital
muxes, but then we wouldnot be able to turn up the power on the
exesting digital channels. I suspect a comprimise will be found with
another 2-3 digital muxes?



also...
It strikes me that there must be millions of portable (and hand-held) TVs
out there which rely on loop aerials and telescopic aerials used in
locations where a rooftop aerial is unavailable or impossible to provide.
Will hand-held TVs become a thing of the past? or will increased digital
signal power mean that digital versions become practical?

What about 'analogue' teletext?

How am I going to read the subtitles on my opera laserdiscs if I need to
buy
a new digital only TV?

Well you don't need a UHF tuner for analogue teletext... it will pass down
composite video/scart just fine. You probably don't mean that, you mean
that TV's will no longer include teletext decoders, which is possibly
true.

That's why I said, "What about 'analogue' teletext?"

Nobody really knows, so its a waste of time speculating.

Power will be increased, so we are told, but another Mux or even two
have not been really been promised.
so I expect we will still have the same crap we got now, because then
they will push more channels into the space and do not have to worry
about upseting people, since anyone who wants T.v will have to use digital.

this is where there have been no thought and all Crown Castle and the
government wants is money, fill there own back pockets and they do not
care one bit about the public.

I got a nice portable T.v, which gives a good picture and since it is
used up here in the computer room, analogue is more than ample for it,
but in a few years time, I will be expected to buy a digital box for a
T.V that at that time will be worth less.

DAB sounds worse than FM wrote:




You could use Wi-Fi for distribution around the house and UWB for close

Wi-Fi uses high end frequencies, over and above microwave.
We get enough problems with some people worried about mobile phones, can
you imagine what it will be like with Wi-Fi?

You will have at least another 10 years to buy an analouge T.V.
after all if have taken more than that to get where we are now.

My point is that current licencing sees the phone as a phone, supplied by
one type of company, and TV as TV, supplied by others. If phone type
technology works to supply video to small devices then TV companies should
be allowed to use it for broadcast TV.
