Well London Analogue TV finally bit the dust in the early hours of this morning, believe it was 1965 that uhf colour PAL started broadcasting so its served us well.

Still reckon, HD aside, that a decent analogue signal picture was miles better than the rubbish digi crap served to us.

The bit I dont understand, is London was planned to be one of the first to go full digital but was delayed due to our winning the Olympics bid back in 2007, this allowing the visiting aliens during that period to watch the Olympics on there portable TV's?.

So why the switch off 100 days before the big event!

the interesting bit is the reallocation of broadcast frequencies , some of which are delayed till after the olympics because..... 




the reduction of channels for professional wireless audio use  mostly radio mics,  would mean insufficient bandwidth tio allow the olympics to be broadcast effectively.

after the olympics.....  the UK will be incapable of staging such a large scale live event and broadcasting it effectively.     the technology and hardware simply does not exist...    not to mention the several hundred thousand units  that will over night become illegal, and eventually useless as other signals fill their previously allocated airwaves.


and is anyone actually going to be effectively compensated?  err, no.....    the "measures" in place are so convoluted , and restrictive, as to be worthy of the douglas adams style  "for all practical purposes, zero"  phrase.

Took me ages to returned my box as the writing has worn away and i only use 4 buttons. can't notice any difference if there is one

Digital quality will always be worse as its a compressed image 

The basis of the entire setup is to send guesstimate picture difference information so as to reduce the required bandwidth (or the bandwidth requried would be about 8 times that of analogue) hence its a bog compromise. Throw in a bandwidth limit and the result is poorer pictures.

I reckon digital TV isn't a bad compromise, actually. Yes, it's compressed and you can see artefacts of that in the picture, especially in the non-mainstream channels that get their bitrate squeezed, but the PAL colour system was pretty compromised itself (and compressed, in fact, just in a different manner) and generated visible artefacts in the picture too.

What DVB does give you is a much more robust transmission standard, so you're more likely to get the same standard of picture in the average home as you would straight from the broadcast stream.

Analogue TV was very sensitive to multipath and fading, and the impact of that was directly visible on the picture as echoes and ghosting. DTV, whilst still affected, of course, does a much better job of mitigating it.

More recent TVs have incorporated pretty sh1te analogue decoders as an afterthought, IMHO, which hasn't helped matters.

So, yes, if you were lucky enough to get a line of sight signal from the transmitter and a good PAL decoder you'd have got a better picture in some respects, but you'd be missing all the Shopping/God/"Regurgitated old bilge" channels that DVB has brought us, wouldn't you?

Contrast it with DAB and DVB has been a great success.

We've had digital for about 3 or 4 years here and it's shite!    You'll have to get used to alot of pixalation, popping, and loss of signal!!! 

[the alarming man]

same here possibly due to the blue bell transmitter...

[tigers_gonads]

Had digital up here for years now and never had a problem.
In fact the signal is better now since they switched the anologe off 2 years ago

Well, that's how it goes. You need to achieve a good enough signal to give you a margin above the point where you get artefacts like that, whereas with analogue you could put up with watching a poor signal to a certain extent.
