Sveriges Radio DAB2
|
The swedish government gives SR permission to test DAB2.
|
Endless testing indeed. I don't get how you can put up with such
|
The "problem" is that nobody like the old DAB.
There are max 7000 DAB listeners now i Sweden.
The government that pay for the transmitting system
think the old DAB is too inefficient and expensive.

bureaucracy.

There's 2 alternatives:
1. The *Incompetent* Way
Adopt DAB early on, then realise that DAB is a terrible system that is
totally inadequate for the demands required of it in the 21st century, but
only realise this 4 years AFTER they've begun heavily promoting it, thus
making it impossible to switch it off immediately, thus requiring many more
years of running MP2 services, thus ensuring that the audio quality is low
for these many more years and ensuring that the range of radio stations is
also low for these many more years, as well as limiting both the quality and
choice of mobile TV channels and other data services that can transmit on
the DAB system.
2. The Right Way
WAIT UNTIL there is a SUITABLE system, THEN AND ONLY THEN adopt a SUITABLE
system and enjoy high quality from day 1 and enjoy a wider range of stations
and a wider range of mobile TV channels and a wider range of data services,
and laugh at the incompetent countries like the UK and Denmark.
|
As for Denmark, if DAB2 gets off the ground, I am sure an additional
network of transmitters will be quickly installed to cover the whole
country. And since the public has learned to adapt to new technologies
and take advantage of increased programme selection - they will enjoy
the new audio quality as soon as everybody else.
In the meantime we have had a taste of the future in the moderate
success of DAB.

|
Well, I think there are other factors in play when a country is
reluctant to introduce many new free but exclusive radio channels that
have to do with media policy. I'm not thinking about technical
considerations which are beyond general comprehension.
|
Ultimately, it does boil down to the fact that *if* the old DAB system were
good enough then the old DAB system would be sweeping across Europe as we
speak. And by "good enough", that is an all-encompassing "good enough", i.e.
it must be cheap enough to transmit, allow enough stations to transmit, and
the audio quality must be good enough.
|
It is fortunate that some enlightened people like the members of this NG
take a stand on technical standards. I think the same non-technical
factors that have caused the failure of DAB in Sweden will also play a
part in DAB2 in Sweden.
|
We'll have to wait and see.

This passage is interesting:
Kodningen i nya DAB2 innebär också en fantastisk möjlighet för
musikälskare: att för första gången digitalt i Sverige kunna få ta emot
musikradio med full ljudkvalitet, alltså en sorts HD-radio, utan minsta
brus eller förvrängning av signalen.
Promises the possibility for HD-radio without noise or distortion.
Provided that uncompressed mode is used. Didn't they make similar
|
Uncompressed?
|
(Det här förutsätter förstås att Sveriges Radio beslutar att t ex lägga
ut P2:s sändningar okomprimenrade i nya DAB2, något som vore fullt
möjligt och som då skulle ta samma plats i etern som tre-fyra vanliga
DAB2-kanaler.
Något sådant beslut finns inte förberett på SR idag, men nu finns alltså
möjligheten.)
A precondition of that [i.e. distortionfree sound] is of course that SR
will decide to distribute e.g. P2's [i.e. classical music] programmes
uncompressed in the new DAB2, which would be perfectly possible, and
which would occupy the same space in no. 1 [...?] as would 3 or 4
ordinary DAB2 channels.
|
Make that:
"and which would occupy the same space in the ether as would 3 or 4
ordinary DAB2 channels."
|
Such a decision has not been prepared in SR today, but the possibility
exists.
|
3 to 4 times the bit rate of an ordinary DAB+ station still wouldn't be
uncompressed - you'd need a full DAB multiplex for a 1411 kbps uncompressed
bitstream to be transmitted. Presumably they actually mean that the audio
quality of P2 should be indistinguishable from a CD.
|
Compression could also mean: dynamic range compression or other
processing. In fact leaving that out would improve the sound of digital
|
Perhaps, but they did mention that the station would consume 3-4 times as
much bandwidth as normal DAB+ stations.
|
broadcasts significantly whatever the bitrate.
gr, hwh
|
Anyway, it's just an article on a web page, and they're usually written by
people that don't know much about bit rates vs quality etc.
|
|
|
promises at the introduction of DAB?
|
They have never introduced DAB.
|
|
|
The article seams to fix up DAB2 with DMB (and trow in "HD-radio" too).
Any idea what exactly has been descided? Is this for pure radio or for
mobile TV too?
|
We have to wait and se. This is about radio transmission
and maybe via the terrestrial digital TV system (DVB-T).
They want to test new standards and alternative methods.
Old DAB has no future in Sweden. That's for sure.

Cheerio! Kr. Bonne.

Any chance of a translation, or if not a brief summery.
