"DIGITAL RADIO IN BRAZIL - IBOC IBIQUITY X DRM"

"Brazil is running to choose between the IBOC IBIQUITY or DRM... The IBOC is very expensive and can exclude most part of little radios in 3rd world... the Brazilian government is tending adopt IBOC under pressure..."

It must be iBiquity's arm-twisting thugs at work, again ! Good luck to either one, since they require the purchase of expensive, new receivers !

Yea, ya better watch out there "linty" The Ibiquity folks have your address and will be knocking on yaw daw soon. Better make sure your security system is in top shape.

So, we are back to stalking me again ? You seem convinced that I have done something libelous and that you have my address. Did you ever follow-up on your threat to call the Greg Smith in Olney, Md. ?

I read rec.radio.shortwave, alt.radio.digital, and ba.broadcast daily and DRM is failing to take-hold - I see such topics as, "DAB, DAB, what is it good for?"

Geez, that's some sense of humor you have there "Linty". Remember this line from your own post?;

"It must be iBiquity's arm-twisting thugs at work, again !"



Yea "Linty" It was you who concieved the while "thugs" issue. Maybe a night away from your computer will help you relax.

DRM will only work in countries with relatively few AM stations, because each station will require TWO frequencies..one for analog, the other for digital. In many European, Asian, and African countries, that's not much of a problem. Throughout much of the Americas, it's a massive hurdle. HD is more spectrum-efficient.

But don't forget that analog is still the most spectrum-efficient of all. Why, you can put 10khz of audio in only 20khz of bandwidth.
Try to do that with HD-IBOC. What? It needs to be 30-40 khz wide? Sounds wasteful to me.

Why should the IBOC signal be just as wide even if the data is silence? That's wasteful of spectrum, too.

 

[Mike Walker]

Actually analog is more efficient than that, Tom. Of course you know this (being a radio "nerd" like me), but half of the bandwidth on an analog AM station is wasted, as one of the sidebands (take your pick) is redundant (they're identical, but in opposite polarity). If spectrum efficiency is what it's ALL about, kill one of da' sidebands!

"Brazil to Reduce Tax on Imported HD-R Gear?"

"Brazil's Minister of Communications says that country could adopt HD Radio by September and allow transmissions at the beginning of 2008... According to the report, Minister of Communications Hélio Costa indicated that Brazil will likely adopt a hybrid of IBOC for AM and FM and Digital Radio Mondiale for shortwave."

DRM for shortwave has stalled in Europe, DAB has stalled in Canada and interest is slowing in the UK, and there is no consumer interest in HD/IBOC in the US - lots-of-luck, trying to sell new digital receivers !

FMeXtra is much more spectrum efficient then HD radio, offers equal fidelity, the same codec (aacPlus), better range, simpler design, cheaper implementation, got FCC final approval before HD radio, and does not jam adjacent channels.

AM sidebands of "opposite polarity" would cancel and leave just a constant carrier. You must mean the sidebands are spectrally mirror images, above and below the carrier. Not the same thing as "opposite polarity".

 

[Mike Walker]

Sorry Supercaster. I must've started drinking earlier today. Take two. The sidebands are identical (in theory at least, there are SLIGHT differences in frequency response occasionally). Only one is required for proper playback. Hence: "Powerside" by crazy ole' Leonard Khan!

It's interesting to see you promoting single sideband Powerside type transmission (a la Kahn) in spite of the fact that with Powerside the carrier remains, just not one of the sidebands. Perhaps Leonard was not as "crazy ole' " as you seem to say.

Hey look, my comments got noticed - maybe, we can help derail HD Radio in Brazil !

Do you speak Portuguese?

In any case, the largest of the group operators in Brazil have already committed to HD. Since Brazil is the second largest economy in the Hemisphere, and they have several thousand stations, this is a major advance for HD.

Just as with the digital radio around the world, HD Radio will be met with consumer apathy in Brazil - they will never convince consumers to purchase new digital radios, when existing analog radios work just fine. HD Radio hasn't even registered with consumers in Brazil, yet:

"Your terms - "hd radio" - do not have enough search volume to show graphs."

I'm not sure what the state of health is for SW in general, is there still a world audience for it?

I do know the FCC adopted DRM for use in HF broadcasting in the U.S. in March 2005.

"DRM - Do the Right Marketing"

"Unless this marketing issue is addressed, only a subset of existing shortwave listeners are likely to be interested in DRM. Consequently sales of DRM-capable receivers - when they eventually appear in significant numbers - will be low, and the momentum will be lost. The majority of consumers will not even be aware that there's a digital AM broadcasting system out there, especially as they need to buy a new receiver before they can hear it. And since the total number of hours aired by the international broadcasters continues to fall, the selling of the medium in terms of listener choice becomes harder and harder day by day."

http://www.radionetherlands.nl/features/media/features/drm050113.html

I read shortwave message boards daily, and SWL is certainly dying as broadcasters move to the Internet and satellite radio. Of course, there are many listeners in third-world countries who can bearly afford analog SW radios, let alone new, expensive digital SW receivers.
