Ho HO!
Me thinks he hasn;t experienced digital tv/fm yet!

My earlier post said I DID hear IBOC in Las Vegas last April.

What makes you think I haven't seen digital TV?

Read me.
Not 'seen'.. Experieinced.
We WERE talking fringe here I thought...

That's why car radios should have a compression function. Not why the
source should be compressed.

It's all Motorola's fault.

I don;t get it... TWICE now I had to get a lo-end rental and they BOTH had
automatic-volume-compensation features on the sound system... Somebody can;t
but a cheap compressor in there???? Hell relicense a dbx-II encode chip and
be done with it... It could HURT most of this stuff on the road?

What would you label the button so as not to confuse the user?

Yes, I can't disagree that in a perfect world it is the right way to
do it. In the real world, "Should have" don't cut it. Things are
done the way they are due to the evolution of the technology. If they
knew back then what we know now, things might not be that way now.
When all cars have local compression that would be a first step toward
correcting. In the mean time, turn off the damn radio if it offends
you.

I have already done that, problem is the dynamic range compression on
CDs is getting as bad as the radio.

So, it's just like FM, only more so?

Digital does not break up in multipath situations. no more "picket
fence" effect.

Yeah, with multipath it just gives up.

The way it is being done now and will be done for some time is to have
both the existing analog and the new digital signal. The digital
signal has to be delayed for error correction purpose and also the
need for a buffer in the consumer's equipment. I think it is like 5
or 10 seconds delay. The plan is to delay your analog also so they
will be in sync. When signal conditions favor the analog, the
receiver will switch back and forth as needed. At this point in time,
since virtually no digital receivers are being manufactured yet some
of the few stations that are broadcasting IBOC have not yet time
aligned their analog and digital signals. When lots of people are
listening digitally, that will be very important.

The name for HD radio, IBOC stands for In Band, On Channel. Which
means the digital signal is placed in the same band on the same
channel as the analog signal. That is why the total IBOC bandwidth is
only 96kbps. That's all the bandwidth available in the existing
service.

Yeah, with multipath it just gives up.

I don't think so. Either the signal makes sense digitally or it
reverts to the analog, which may sound like sh*% but I don't think it
will ever just give up.

Sadly there is. With IBOC, the digital signal is transmitted as just a
subcarrier on the existing analogue signal. It's no relation to the
Eureka-147 L-band system that most of the rest of the world is adopting.

Just downloaded 6-9; I see what you mean. Thanks for pointing these out.
Wish I'd been in time to grab the earlier ones. If we're lucky, the BBC
may put 'em out on CD...
