Re: DAB digital radio - Sharp FVDB1 £49.99 at Richer Sounds. Bargain?

DAB sounds worse than FM a écrit :

No. DAB *is* a crap system. If you don't understand why it is a crap
 system then that is not my fault, but it does *not* get away from
the fact that DAB *is* a crap system.


I understand the word crap, and it's an impolite word ;)



If you support the use of DAB then I can only imagine that you must
kill a lot of your patients! ;-)


I was sure you say that :)


I agree. But by the time France wants to start transmitting rolling
out digital radio then it'll have tried and tested systems to choose
from!


And in few years, there are another best system in developping (moore's
law in fact ;) )
Which system must be use in this condition ? The "best" will be always
developping. so, nobody will never choose digital system.
PS : When I tell about DAB I think DMB evolution. Same broadcast
network, so it's low cost evolution.


Have a look at VDL Paris and Lyon:

Yes I do, but so I look TDF broadcasting !

You will not get 192kbps stations. 

Why not. It's true in england, it's false in denmark, in Portugal,
in Germany. experience prove we can get 192 kbps stations ! That is
a fact, not a dream !

And how much does it cost to implement DAB compared to other
systems? The answer is that DAB is very expensive to implement
compared to DMB, DVB-H and DRM, which will mean that they will
try and reduce bit rates in order to lower the cost of
investment, which will result in you not getting your 192kbps
stations.

waiting ! cost of DAB is known today,



It is *very* expensive to transmit per radio station. 

perhaps, but it is known !
DMB is near the same than DAB, but three times less in 64 kbps AAC+/DMB
than 192 kbps mp2/DAB
But for DVB-H we wait berlin experience for that for example.

but you can't argue with DMB, DVB-H or DRM. No one has begin
developping this systems. It's theorycal

What???????????????????????????????? 



Both VDL and TDF(?) said they wanted to use 128kbps for stereo
radio stations on DAB.

VDL and TDF broadcast radio station programs. they don't impose bitrate. MP2 is an old codec, so encoder are better today. 

MP2 is an old and inefficient FORMAT. You cannot change its bitstream
 format.


With DAB certainly not

128kbps isn't the better bitrate with the better codec. We are OK. It will be the same with AAC+ and others ! In few years ... (certainly)

What will be the same in a few years? 

IN a few years, needed bitrate on AAC+ will be down for the same audio
quality, when encoders will advance.
And story will begin back.
