Just because I'm in a generous mood (and because I have nothing better to do with my free time), I'll run through this article like I did the one below. The article, written by John Quain and published in yesterday NY Times, is titled:
Local Radio Is Cutting the Static and Going Digital, Finally
As drivers pick their way down the West Side Highway of Manhattan, the noise is often more annoying than the traffic — and it's not just the honking.
It's the gunshots and screamed obscenities as well.
What's so irksome is the static from the car's sound system, a result of congestion in the radio frequency spectrum in an area packed with AM and FM stations. But that analog annoyance may fade away as radio broadcasters, carmakers and consumer electronics companies make the transition to digital radio.
Or so we're told, we still can't find any well-known brand name other than Boston Accoustics who actually
makes an HD radio.
While satellite radio customers have enjoyed the clean, crisp sound of digital reception, most people tuned to local stations are listening to analog broadcasts based on technology little changed in the last half-century. But more and more broadcasters are pushing a digital format called HD Radio, which rivals satellite radio quality and promises to eliminate the static.
Bringing you the same crappy programming with a crisper, cleaner sound!
Introduced three years ago, HD Radio is the brand name for a technology developed by the iBiquity Digital Corporation of Columbia, Md. (HD is not an abbreviation for high definition, as it is used by television broadcasters).
Let's just imagine how that might have gone down had the topic come up at the end of the interview, shall we?
QUAIN: So, HD, that stands for "high definition," right?
FERRARA: No, not really.
QUAIN: Oh... okay, uh... what does it stand for, then?
FERRARA: Mmm... nothing, really.
QUAIN: Soooooo you named it "HD Radio," but "HD" doesn't really mean anything?
FERRARA: Yeah, pretty much.
QUAIN: Alright, well, it's been a pleasure talking with you, you're a real jackass.
FERRARA: Well, thank you, I-- HEY, WAIT A MIN--
CLICK.
The HD system digitizes and compresses a station's signal; the digital stream is then broadcast in the same frequency range...
(And beyond.)
used for the station's analog AM and FM transmissions. The digital broadcast is sent alongside the analog signal, so you can listen to either analog or digital versions of the same content...
No, actually, you'll be listening to both at the same time... unless what Quain was trying to say was that there are additional subchannels, in which case he could have phrased that part of the sentence this way:
The digital broadcast is sent alongside the analog signal, so you can listen to either the station's primary programming or additional, secondary programming.
See? Geez, if I can do a better job at editing The New York Times than The New Yorks Times editors can, you know something's wrong at 1 Times Square.
...and more important, there is no subscription charge.
(Yet.)
The HD signal also carries artist and title information that can be shown on the radio's display panel.
Which is what RDS is supposed to do, but given the lack of support most radio manufacturers have shown for the technology, it hasn't really taken off. (Yes, I realize it's out there in large numbers, but is it on your new Walkman? Is it on your new boombox? Is it on that new home theater receiver you just bought? I rest my case.) In any event, given the lack of support manufacturers are showing for IB(A)C, I'd say it's probably going to go the way of RDS... if not the way of AM Stereo altogether.
The sound improves over a conventional AM station by delivering a better dynamic range — the difference between quiet and loud sounds.
Strange... I'd think that with all the horns, guns and expletives outside the car, you'd want less dynamic range so you can hear more of what's coming through your radio and less "Get the **** off my ****ing car ya ****ing ****er!"
In addition, HD is better at reproducing the high notes of music...
Well, not really. HD just adds them where they previously were absent. If FM radio didn't have to roll off at 15kHz to protect the stereo pilot and AM didn't have to roll off at 10kHz to protect adjacent stations, they'd actually sound better than IB(A)C. IB(A)C isn't actually all that great when it comes to reproducing those highs. I've heard it. It ain't pretty.
HD is capable of highs up to 15 KHz, compared with the current top end for analog AM of 10 KHz, making it sound as good as a traditional FM station.
No, it really doesn't. It sounds like total garbage. The highs are highly digitized and warbly. It rivals a low-bitrate Internet stream at best.
Better yet, HD FM stations can deliver audio that is nearly as good as a CD in quality, with a frequency response of up to 20 KHz, comparable to satellite radio.
I find it interesting that they're feeding us the line "nearly as good as CD-quality" now. Three years ago they were telling us it was as good as CD-quality. But in reality, it doesn't even come close to nearly as good as CD-quality. It's more comparable with a 64k AAC+ stream... which, in actuality, it is an AAC+ stream, run at 96k nominally if there isn't a subchannel on the station. However, given that a single subchannel is nominally 32k, and also given that most IB(A)C stations are running one, if not two subchannels, the highest you're going to get out of an average primary HD stream is likely only 64k (96-32=64 for those of you who aren't mathematically inclined), and since even 128k AAC+ Internet streams just barely scratch CD-quality audio (I'd say it's just above 256k MP3 quality), I'd hardly call a 64k IB(A)C stream "nearly as good as a CD in quality."
To get this higher fidelity of HD broadcasts you don't need a new antenna. But you will need a new radio tuner that can detect and decode the digital transmissions.
For which you'll currently have to drop around $250. That's for the low-end models.
"There was the proverbial chicken-and-egg problem," said Peter Ferrara, chief executive of the HD Digital Radio Alliance, a consortium of broadcasters including ABC Radio and Clear Channel Communications. "Consumer electronics people didn't want to make radios until there was content available, and broadcasters didn't want to invest in putting out the content until radios were available."
That was never the primary problem, and Ferrara knows it. The problem always was and still remains that manufacturers don't want to spend the money on the licensing fees (which are ridiculously high, not to mention the fact that they exist to begin with... there's no licensing fee for analogue radio!). Not to mention that if they do spend the money, they'll have to pass that cost down to customers, and the average customer doesn't want to pay the one-time extra cost on each radio they buy. That's the risk that the companies who are making IB(A)C receivers are taking: how much are they going to spend until they figure out the public isn't interested in the technology? Most companies don't want to play that game.
But broadcasters decided to take the plunge at the end of 2005, according to Mr. Ferrara, by forming the alliance to promote digital radio and by committing to introduce HD Radio stations in the nation's top 100 markets. That rollout is nearly completed, with 1,204 stations broadcasting in HD Radio as of last month, reaching a potential audience of 235 million listeners.
No, right now they're reaching a potential audience of about 3. 235 million listeners do not have HD radios.
The alliance expects there to be about 2,000 stations broadcasting in the digital format by the end of the year. (A list of stations that broadcast HD is available at hdradioalliance.com.)
And in the future, those stations will be known as "dupes."
Satellite radio initially gained traction by adopting a marketing approach similar to that used by cellphone companies. XM and Sirius entice listeners with relatively inexpensive tuners, often less than $100, but then charge buyers a monthly fee of $10 or more. HD Radio took the opposite approach: tuning in was free, but early HD-compatible radios were nearly $1,000.
Now they're just less over-priced.
But prices have dropped, with tuners costing half that much or less. JVC's in-dash HD-W10 Mobile HD Radio, for example, costs $188 and includes a CD player. Wal-Mart began selling the JVC model at about 2,000 stores this month.
And it will be off the shelves in two months. You watch.
Carmakers have been much slower to adopt HD Radio. Among the major auto companies, only BMW, which had previously limited HD as an option on some premium models, will offer the HD Radio option on all of its vehicles this spring.
But if you want an affordable car with HD standard, you're SOL.
Add-on HD Radio tuners are also available. The Directed Car Connect HD Radio, for example, is $199 and connects to jacks on the back of existing in-dash head units using connectors known as RCA plugs. The model includes a display that can be mounted in or on the dash, but the company recommends having a professional install the tuner.
Visteon, the automotive electronics supplier, will also offer a similar product called the HD Jump for $249 next month. The HD Jump will include a cradle so that it can be used not only in a car, but also at home as a tabletop HD Radio.
Because we weren't innovative enough ourselves, so we just ripped the idea off'a XM.
While HD Radio does not offer a breadth of programming for different tastes comparable to XM or Sirius, it has thrown a new ingredient into the mix: multicasting. Also called HD2, multicables...
"Multicables?" I think that was supposed to read "multicasting enables," but one can never be sure. Again, editors? Where were you on that one? (By the way, here's the link to the original story so you can see that it really was written that way and that I'm not just trying to make the New York Times look bad. They're doing a pretty good job of that on their own so far.)
...individual HD stations to divide the digital stream into as many as eight separate channels within their existing frequency.
I certainly hope he means eight separate channels as in, "eight separate channels allowing for four different programming options; the primary signal and three different sub-stations. " Otherwise, I could go sit on the toilet right now and make noises that would sound better than the audio coming out of a stereo tuned to a station that broadcasts seven subchannels in addition to their primary signal. Though, for that matter, the bathroom noises would probably sound marginally better than a station broadcasting three additional subchannels as well.
For example, about 500 stations offer a second HD programming channel, enabling them to appeal to smaller audiences in niche markets. WKTU-FM in New York uses its second channel to broadcast country music. In Dallas, a Clear Channel station, KHKS-FM, offers Pride Radio for a gay audience on its second HD channel.
Which is really just a dance station, and I frankly find that rather sexist of Clear Channel to assume that A) only gay people listen to dance and B) all gay people listen to dance. I'm straight, and I listen to dance. I also have gay friends who don't listen to dance. See how that works, Clear Channel? Geez...
By the way, I can't be the only one who noticed Quain didn't specify KTU as a Clear Channel station. I doubt there's any meaning behind that fact, I just found it odd that he mentioned Kiss 106.1 as such and didn't add that KTU is as well.
Nationwide coverage and acceptance of HD Radio is probably years away.
If ever, God forbid.
One impediment is that the average cost for a station to add HD is about $100,000, according to iBiquity and the HD Alliance.
Another is the fact that it will obliterate the AM band, home to some of the most successful stations (and, in some cases, the most successful station) in most larger markets.
And although several automakers have said they would offer HD Radio as an option, none besides BMW have made any announcement.
Good! Let's keep it that way!
"It's the last medium that hasn't converted from analog to digital," said Rob Lopez, national marketing manager at Panasonic, which has offered an in-dash HD Radio unit for several years. "So I'd like to think we'd see HD Radio as a standard feature in cars in the next five years."
"Though I'm most likely wrong in that line of thought," he added.
William Scully, a BMW spokesman, pointed out that listeners didn't necessarily have to choose between satellite and HD Radio.
"It's not an either-or kind of thing," he said. "Our Logic 7 combo models come with satellite and HD radios."
So not only can you get better programming, you can get additional crappy programming as well, all for three times the price! Whatadeal, whatadeal!
So ultimately, one way or another, car radios will enter the digital era.
But only with the addition of WiFi connectability.
And that will bring better sound into autos, so that the only static you get in the city is from other drivers — not from the radio.
Just try to dodge the bullets.
