One of the turning points on the way to the demise of traditional
broadcasting in the USA was the NAB's flat refusal to adopt Eureka 147
because legacy stations would lose their higher-power legacy facilities
and AM would have equal footing with FM.
Eureka did not even get to the NAB level; the band in the US is reserved for
military uses. It has failed miserably in canada, too.

Actually, NAB management initially supported Eureka 147 but then had
to back away when faced by a revolt from its members.

That is my understanding as well. The protocol can be applied anywhere
in VHF/UHF. While the L Band is used by Boeing and Rockwell; at the time
the S-Band was wide open and was already allocated to sound broadcasting.

Radio World saw, by invitation, the SiPort chip.
I don't know what they saw. Did they see it work? No. Did they see it
installed in a prototype operating? No.
Actually, they saw both.
Actually did not see it work.

Show me a link.
They saw the prototype working. Buy a subscription to Radio World or shut
up.
Shifting the burden to the person one is trying to
convince is no way to make a point.

If the point Eduardo is trying to make were a
good one then it would be supportable with
multiple independent references.

As unbelievable as it may seem, not everything is on the Internet. The
dealings of Samsung and SiPort are directly with iBiquity and receiver
manufacturers, of which there are relatively few in the world. There is no
need to have an internet presence for the chips, as the appropriate people
already have samples, and are proceeding to the design phase of the process.
There is no purpose in promoting chips to consumers, just the manufacturers.

Anyone who wanted to see the chips working could at CES. Articles in paid or
controlled subscription magazines and newsletters have covered the
developments, including Inside Radio and Radio World. There is lots of
documentation, but all of it requires either going to CES or having
subscriptions to the publications; Inside Radio is about $400 a year, for
example.



The only people putting money into this turd are dinocasters and
American carmakers. That should tell you something.

Since then, Sirius and XM filled the void. Radio has been bleeding red
ever since.
No, satellite has been bleeding. Clear Channel had EBITDA of $1.8 billion
last year while the satellite companies collectively lost $1.6 billion.

Radio billings were up 2% last year.
Everybody's bleeding 'cept for me and my monkey.

No, you are just lying and making up statistics that do not exist. Billing
back to the 60's is on the RAB website.


Y'all are bleeding audience, if not cash. How much of that CCU figure
was TV? Outdoor? Attractions?

Looks to me like the Samsung chipset is klunky compared to the competitor:

"...Samsung's HD Radio baseband processor, based on Tensilica's
programmable core, integrates the baseband, memory, SDRAM and flash in a
system-in-package measuring 9 x 9 mm. Including the companion RF chip,
the chip set's total power consumption is 150 mW...

...Sunder Velamuri, vice president of marketing at SiPort, said power
dissipation of the mixed-signal device is expected to be "around 100 mW
in typical configurations." He added that the chip, essentially "a
software radio," can tune and demodulate not only analog AM/FM and HD
Radio but also DAB and DMB-T, making it ready for the global market.
Taiwan Semiconductor Manufacturing Co. is fabricating the device..."

There are no chips developed for HD radio. Sansung and TI have some
years old notes on how you can use a set of their respective general
purpose chips DSP/CPU and analog baseband devices to make an HD radio.
For these parts to work as an HD radio they need additional support
devices and the license to use the ibiquity software. A lot of power
must be used to drive all this.

That's not what it says. It says it uses ca. 100 mW in "typical
configurations". It says it "can tune and demodulate" so I would think
any "additional support devices" wouldn't be that big a deal.

Maybe you should take a look at the proposed block diagrams before you
open your mouth and the specifications I read were 500 mW not 100 mW.

In fact, since the dot com bubble burst, there has been a major
decline in the availability of technical material on the 'Net
(many citations available on the Web and Usenet archives). In
my personal experience I have found that the usefulness of the
'Net to obtain arcane and especially mature technical material
has declined to deplorable levels. I used to be that nearly
everyone with any digitized material made it available by ftp,
gopher, or the web; now if you are very lucky sometimes you
can stumble on things in binary newsgroups or peer-to-peer
if you are really clever. The cost of storage has declined to
the point that it cannot be an excuse for the deletion of
'legacy' material on the part of larger firms; there are obviously
other (perverse) reasons behind it.

I'm not sure what it is you are addressing here but the subject is what
is available from the semiconductor web sites. I can tell you for a fact
that any manufacturer out there recognizes the benefit of getting their
products on their web sites. I use these sites all day long looking for
components to incorporate into my companies products or for automated
test. Doesn't matter if it is a 1 cent resistor or a $100K network
analyzer, my search starts on the web.

For chips that actually exist you can find its full specifications,
application notes, and if it has a complex or difficult implementation
it will have a reference design that some application engineer put
together. And of course you find news like when samples will be
available and when production will commence.

What's up Eduardo. Where are those quotes from Radio World?

Try getting NXP (ex Philips) to understand that ;-(

Again, it very much depends on your choice of vendor; some have websites
that are truly impenetrable. I find myself going first to datasheetarchive.com
nowadays. And when I design with 'mature' devices, I can forget most manufacturer's
websites as a first choice; the chips 'exist'; it is just that the vendor
has chosen to make using them difficult.

In my previous post I was bemoaning the elimination of mature software, manuals
and datasheets that cost very little to host, which seems to be the result
of company business decisions and ownership changes, and also the loss of many
private sites that used to mirror such materials -- gone for undocumented
reasons. As to new announcements, I used to get some 80 trade journals per
month (the bingo-card renewal process took a lot of time) and found that
I was better informed with the mass of paper than I have ever been on the
'net.

If you ever feel like getting lost in a web sit try Agilent. It is a
truly massive site that their own people can not navigate.

Funny. My BMW came with HD. BMW is German, in case you are so clueless as to
not know.
