Hint at future capacities for HD Radio

C

Carmine5

Although not nearly as interesting as the EXB proposal, this article in RBR hints at some future capacities for HD Radio, including navigational mapping, HD3 multicasting and personalized data services.

http://www.rbr.com/radio/ENGINEERIN...evenue-generating_options_for_extended_h.html

Here's a quote:

"Multicasting additional program channels, adding personalized data services and leasing band space to content providers are a few of the options available to HD Radio broadcasters, who have 50% more available digital capacity compared to last year at this time.

The additional digital capacity is due to the September 2007 ruling by the FCC authorizing broadcasters to increase from 96kb/s HD Radio hybrid up to 146kb/s extended HD Radio hybrid operation. No additional hardware is required of HD Radio stations to begin broadcasting the expanded bitstream, and few, if any, additional hardware or software is needed by most BE customers to add new programming and text services."

Apparently, BE is developing ways to slice up the band "pie" even thinner with more channels.

They've also included in their equipment the "AEROMAX-HD2SC audio processor by Linear Acoustic made specifically for low bit-rate HD Radio audio."

Absolutely! EXACTLY what radio broadcasters need: more products to conceive, install, program, maintain and sell! ::)

One would think that the ancient truism might have dawned on HD promoters by now: "you can't give 100 percent of your attention to more than one thing at once." (And the more fragmented your efforts, the less effective they are.)

Can't sell the main analog channel? Let's add HD subs. Can't sell the analog or the subs? Let's add personal datacasting, program content, more multicasting....oh, and while we're at it, let's compete with TomTom and Garmin!

And the COVERAGE is so effective too......
 
What's that old expression? You can put lipstick on a pig but it's still a pig?
In this case substitute the word bomb for pig and it's pretty accurate.
 
No, actually, with all due respect - the correct quote is:

"You can put lipstick on a Muslim, but that doesn't make him a Christian. Even if he's running for President."

Or in this case it's lipstick and high heels. Still doesn't address the problems plaguing HD Radio and might even make them worse.

But, hey, more is more. More side channels and data streams=more monthly revenue for Ibiquity.

I was kind of curious about this Aeromax-HD2SC and how it actually processes low bit rate audio.

Extended Hybrid mode adds digital carriers which are closer to the analog channel, so if digital injection is also raised 10 dB, the > 99% of the audience listening in analog will be more likely to notice digital-to-host analog interference, aka "self noise", particularly in stereo:

Also, this ancillary data capability is going to flounder as long as the transmission standard is closed and every new consumer product needs to be approved by iBiquity's lawyers. It's fun to talk about all these new text services, bits on the fly, etc, but who owns a radio today that can take advantage of it?

If the proponents really want to encourage innovation, they should make the protocol public and allow the raw data stream to be brought out of the receiver through a USB or Bluetooth port. Right from the start, all HD receivers should have included this port as a standard feature, like a serial port on a PC. This would have encouraged entrepreneurs to develop inexpensive products that would add new capabilities to the base of existing receivers.

I realize this will never happen, which is one more reason the system is doomed.

Can we can the politics, please? Take it outside or something?
 
I just had a brain storm, a great unsung future use for HD radio suddenly just came to me: 200 dollar Door Stops, (gotta capitalize it they usually cost 200-300 hundred dollars) just think these clunky useless radios can now actually do something useful instead of just sitting there hissing at you.
 
Does iBiquity get a payment if an FM runs their sister-station/clustermate AM station's audio on an FM-HD3?
I don't see why every HD-FM station doesn't 'rent-out' it's HD3 stream for the local AMs to use?
We'ver got 4 HD-FM stations with NOTHING on HD2 (or HD3) - so why not put the AM's on there?
 
"I don't see why every HD-FM station doesn't 'rent-out' it's HD3 stream for the local AMs to use?" That's exactly what my former employer is doing. Their AM is simulcasted on HD3. Rumor has it that they will rent channels also. Personally renting out the extra channels is the BEST thing I've seen out of HD, other than that great Sony tuner that they recently put out (used in FM analog mode of course). LOL! Seriously, why not use a sister FM and forget all the hash and costs? Why not let the equipment try to pay for itself by renting the extra channels? With corporate radio companies swirling around the drain hole you'd think they'd be trying to ACTIVELY rent the extra HD channels to special intrest groups right now. I think it would be a decent business model for this MESS.
 
Adding to that, if big corporate would put some support behind these guys with a brain that want to use the channel 5 and 6 band for radio, the long term fix would be there so that even the AMs simlucasting on FM could be rented out eventually. The 5 and 6 TV band idea is a wonderful idea IMHO. It's nothing but positives for everyone involved, even the displaced TV guys that really would have a better signal on UHF anyway.
 
It's an absolutely terrific idea. And it's one which would put many second-echelon AMs on a par with big-group owned stations. Which is precisely why I think it's dead in the water. The big guys and the moronic NAB will stomp on it. What they hope is that HD interference puts smaller guys out of business. That was always part of the plan, which is why the FCC is ignoring interference complaints. The fix was in long ago, so there is no incentive for anyone to change the status quo.

How is that in the best interests of the FCC? Isn't this the same FCC that is hell bent on adding hundreds of small broadcasters on the air? Against the wishes of the NAB. The FCC wants more and more licensees, so they can justify a budget increase to Congress.
 
In one of our discussions, the point was brought up about tune tagging using either a Zune or iPod in conjunction with HD Radio.

There is an interesting new service that will allow any radio station, AM or FM, to be interactive, including tagging and purchasing music. It works with a station's website and a customer's smartphone.

http://www.stratosinteractive.com/sa10.php

A station's contests, promotions, audio stream, etc. can all be accessed by way of a smartphone.

Again, no need for HD Radio here.

In David Rehr's speech at the R&R Convention today he made the point about getting FM radio into cellphones. Again nothing was said about AM radio. Should it ever come to pass that FM radio does get into cellphones than the EXB proposal makes even more sense.

As it is, the only way an AM station can achieve a presence in cellphones is by way of the internet.
