Which will add their own delays...

Why do people want to do this?..

With a population of 5 million, Scotland has less than half the market for local radio of that in London.

Does the land listen to the radio?

London has *one* BBC local radio station. Despite 'my' borough of Wandsworth being larger than many places that have their own. So presumably with at least as many licence payers.

I've always know it as "Closed Circuit Tele-Vision". ie only viewable by those connected to the circuit. No definition or inference as to what a "circuit" was, could be base band video on a copper pair, RF over a coax, IR link, radio link what ever.

Well the one local to me isn't, Can you list those BBC Local Radio stations that are on DAB please?

Well, most circuits tend to use copper conductors.

I don't think there was any suggestion that one of the Cs in CCTV stood for Copper. More that CCTV these days doesn't neccessarily use a "closed circuit", i.e. anyone could evesdrop on a WiFi link.

But if it's a broadcast link, it is not a *closed* circuit.

are a few missing, Manchester and York are still two that spring to mind but a couple of years back there was also Nottingham Leicester and WM missing - but they now seem to have gone live.

lists all the stations so you can see which other ones are missing

Yet another plea for yet more money for some minority service from the English taxpayer for the severely deprived North of the border? If we are going by land area then Yorkshire and Lincolnshire ought to have many times more BBC local stations than London and the home counties, similarly with Norfolk and Suffolk.

True.

Debatable as it depends on how one considers the market, particularly in view of "the unique way [the BBC is] funded".

The commercial sector has a number of local (music based) radio stations in Scotland with varying degrees of success, though Talk

107 has just closed.

Not really anymore.

I used to listen to BBC Radio Bedfordshire which was local to me. Then it turned in BBC 3 Counties Radio when it merged with several other stations, and stopped covering local things or having any local reporters or local news. Then that joined up with loads of other local staions and they all ended broadcasting the same stuff most of the time, and mostly that was utter crap phone-ins (Jon Gaunt?).

BBC "Local" radio was dead by the end of the 1980's. That's a resource which should have been sold off to local enterprises to continue running as local radio sations, given the BBC didn't seem to want to do so anymore. There were already some successful commercial (genuinely) local radio stations.

Even the travel news (the last reason I ever tuned in) had become national and stopped covering any local roads.

I think I have, but if on reflection you still think I haven't, please humour me and explain. Synchronising the sound with the picture makes the delay problem worse. If settling for unsynchronised sound made the delay problem go away, I could see some merit in it. But it doesn't make the delay problem go away, does it?

That's what I'm suggesting, sort of - not a standard design, but a standard outcome. There is a certain delay inherent in each design. I'm suggesting an additional variable delay that will make the overall delay the same for all receivers. This would part of the DAB++ (tm) standard.

I agree with what CCTV means, but a radio link isn't a closed circuit.

I said "when one goes to the trouble", not "when I go to the trouble", and "digital" (not just DAB). And one might replace them all if one wanted digital radio and didn't want unsynchronised sound sources.

I don't think I have.

Two digital TVs are likely to have different delays to the sound - which could be annoying if you can hear them both. Two analogue TVs - probably only CRT types - should be in sync.

So really quite similar to analogue versus digital radio. Except that some TVs introduce an even greater delay deliberately to compensate for their internal video processing.

are yes, he left BBC London, no loss. Phone ins seem to be common on BBC local radio, London has one show worth listening to, 12-3 Robert Elms.

In other words, you *do* get the problem anyway, with digital TVs. So what made you think I hadn't been paying attention?

As I said before, with FM the delay would take place before the transmitter, saving the receiver the trouble.

Sorry - read your original comment incorrectly. It's called a senior moment. ;-)
