Does in the UK

Is that DVB-T2? Is it already fully rolled out?
How many muxes are there on UK DVB-T?
6-8 actual frequencies in use, depending on transmitter - I guess you call that a MUX - of which 1-2 are HD.
gives a reasonable overview.

Ok... 100+ channels on 8 muxes, that will be something...
Indeed I see the HD channels use DVB-T2 muxes. We do not have T2 at all here yet, Germany is in the process of rolling it out I heard.
We have 5 DVB-T muxes with 31 channels in total. So the average bitrate is quite a bit more than what you get.
DVB-T is generally used for portable and 2nd set for the kids or bedroom here, most primary TV viewing is on cable or IPtv.
here most people have DVB-T/T2 and or DVB-S there is virtually no cable at all.
Internet streaming is coming big time and is integrating with DVB-T/T2/S
- I can select a channel on DVB-T that automagically streams internet content. My latest TV even has a button marked 'Netflix'
The idea seems to be to provide one platform that accepts multiple information sources.
Up to and including DLNA material on the local network.

There are plenty of channels but all bar a few are at a very low bit rate and it shows.
DAB? DAB is so bad. Now I listen to DAB because my music choice is not offered on FM radio. But I only have DAB because my wife bought a new unit CD/Radio for the kitchen. It has DAB but she didn't spot that, she bought a CD player that sounded OK and was small. My car has DAB (Band III and L-band) and it stutters and splutters about Scotland. Just a few miles South of Edinburgh and it dies. Huge sections of the main road North has no DAB coverage. There's a bit with no FM as well but FM comes back 20+miles before DAB does. It came with DAB because I wouldn't pay money for it!
BBC R4 is the premium talk radio station. On DAB it's 64kbps mono and sounds dire. So I listen on FM where it is stereo and so relaxed in comparison.
But as the gov here will tell you, look at the choice you get and stop whining it sounds s**te. Although most of the music stations are Bauer Media Group playing the same formulaic rubbish.
Ah, another testcard fan. +1 from me.
most primary TV viewing is on cable or IPtv.
True, outside of the big towns and cities.
Mind you, I am in a suburb only three miles from central Manchester and I seem to be in an enclave of a few streets that were never cabled by Nynex in the '90s

That was the most-used testcard here. Before, the RMA Resolution Chart
1946 was used (BW), and there has been some use of the PM5540 and an EBU chart.

I actually took advantage of that on the BBC Micro to create grey from a pattern of alternate green and magenta pixels. It worked great on all TVs using a RF or composite input, but not when I got a TV with a dedicated RGB input, which obviously had a much higher chrominance bandwidth.

All this talk of PAL and SECAM had me re-reading old copies of Television magazine. I found that of great use as a teenager learning about electronics because it showed real circuits and real in-the-field fixes for the problems. That taught me to think and to observe, think about what is meant to happen and observe what is happening and use that plus knowledge from the circuit to find the problem.
That's the one thing they never touched on in my university degree and that teenage interest in fixing things meant doing the final year project (add-on digital waveform store for a lab oscilloscope) was easy.
Now to read some more of the late Les Lawry-John's stories...

.. and if you are still interested, take a look at:
Colour Television, Vol.2, PAL SECAM and other systems P S Carnt & G B Townsend, ISBN 592 05946 4
Colour Television Theory Geoffrey H Hutson, ISBN: 07 094259 5
Possibly one of these may be downloaded as a PDF. Our final year university course included 8 weeks of lectures from Pye TVT on all aspects of colour television, including transmission and cavity combiners. Great!
I wonder whether similar books will ever be produced about the Raspberry Pi, or whether it will just be a Web archive?
