It's here now

 I've put this text on a pink background as it's fairly close to looking through rose colured spectacles.

Digital TV is here to stay now and, thankfully most pictures have been tailored to minimise digital artefacts and problems, results are OK. Soon HD will bring back decent definition to viewers. I say bring back because anyone with a half decent analogue TV would have been getting something pretty close to HD before the advent of digital transmissions and flat screen sets.

In this area, served by the Rowridge transmitter on the Isle of Wight we will not enjoy full power and 100% coverage till 2012 when most of the UK has already switched over. That at least is the plan... however plans can be changed. One of the reasons for a change may well be that French TV, which has been biding its time in relation to digital has now announced that northern France will lose all its analogue transmissions by 2011. Analogue switch off isn't juist concerned with turning off a bif switch, it's actually concerned with the final rejigging of frequencies.

In order for digital and analogue to co-exist their transmissin frequencies and power levels have to be very very carefully chosen so as not to wipe each other out, and the planning for this must take into account not only transmissions from Rowridge (here in the South for example), but also transmissions from Caen and other French transmitters. So if the French powers that be turn off their analogue broadcasts and turn on high poiwer digital transmitters, this will almost certainly have some sort of effect in the UK.

What exactly?

Well during 2011 the southern area will still be using high power analogue and low power digital signals. The low power digital signals have been carefully positioned frquencywise to co-exist with local analogue signals, not with high power digital transmissikns from northern France.
