High Definition Radio is Here 389

Posted by michael from the high-definition-acne-ads-are-still-acne-ads dept.
nfranzen submits this story/advertisement: "Yesterday, I had the opportunity to buy the first High Definition (HD) Radio in the United States. HD Radio, invented by iBiquity Digital, adds a digital channel to the sidebands of an existing analog FM signal. The technology is still pretty new, but I can tell you first-hand that listening to my favorite local FM station in HD sounds just like I am listening to a CD. Well, except for the commercials (grin). Here are some links to local TV news coverage and a news release for more info. HD receivers will hit the open market following the Consumer Electronics Show next week in Vegas." We had an old story about the FCC approving these digital broadcasts in the FM radio bands.

      Keep in mind that digital signalling techniques weren't really invented at all until the 1940s. And that AM was deployed before than, and FM either before that or not much after.

      Is it inconceivable to believe a brand new field has seen startingly gains in efficiency in 60 years time? Look at how much modems improved (56kps over the same line that once only supported 150bps...nearly a 400 times gain).

      There is no catch. Telecommunications technology has just improved a hell of a lot in the last 100 years.

      This is the reason why cell phone provides are so antsy to relaim all those 6 MHz wide UHF allocations....you can use that bandwidth so much more effectively with modern techniques, instead of throwing raw, uncompressed analog data out there.

      Also witness the huge number of digital channels cable providers have packed into coax, despite the continued presence of regular TV stations, AND internet connections.

      And this is the part where everyone should stop whining about taxes and having to give money to their local learning institution.

      Yes, you can tune in plain FM stations with a HD-FM receiver.

      BTW, digital cellular is popular with the carriers not only because of spectrum efficiency, but because of superior link budgeting with lower output power. The range is actually better on digital cellular protocols (whether TDMA or CDMA) than FDMA/AMPS. The reason why your user experience is better with analog is that there is so much more analog stuff deployed. This is likely to change (not exactly a ton of AMPS equipment is still getting deployed).

      Data compression reduces signal bandwidth. And reduced bandwidth means less noise in the band where the signal is, and also means that the signal, since it is less wide, is stronger. This translates to better S/N and thus better link budget. Also, there are things like coding gain which you can't make use of with analog transmissions.

      I don't know how the HD FM divides output power/spectrum to the subcarriers. But it is likely that you can still get a perfectly clear digital signal when the analog FM station would be unlistenable.

        Well, there is a lot of analog out there, more than digital, but that's not really the problem - the problem is the "digital cliff" effect.

        With AMPS, as the signal gets weaker, the audio noise floor comes up, and you get wideband static on the signal. Wideband static is fairly benign, in that humans aren't as offended by it (since it sounds like the surf). The user of the phone knows he is getting out of range well before the call drops, and so usually can terminate the call gracefully.

        With digital, you get no real degradation of the signal so long as the channel bit error rate is less than the channel's error recovery capability. But when the BER gets above that threshold, then the quality drops dramatically. Moreover, the loss of quality is expressed as garbled vocoder output (I've always described it as "watery" - it sounds like you have water in your ears), or as complete failures of the vocoder (dropouts). Those are VERY offensive to the ear.

        Also, the difference between a signal level that gives you a fully correctable BER and a signal level that gives you a BER bad enough the phone drops is almost nil - so just changing position can drop the call without warning.

        Personally, if the phone makers would tie the received signal strength indicator (RSSI) into a variable noise generator, so that as the RSSI fell you started to get static, I think most people wouldn't bitch so badly about dropped calls.

        There is also the problem that the usual vocoders for phone use are compressing the crap out of the signal - taking a 64 kb/second audio stream down to less than 4kb/sec. VSELP, IMBE and AMBE all do OK when fed voice in isolation, but put in any background noise and they get "confused" - they start making poor choices about the vectors they encode, and what comes out the other end is pretty rocky.

        I had great fun feeding the first few seconds of Kansas's "Carry On Wayward Son" into an APCO-25 IMBE vocoder. While there is nothing but voice there, it is a chorus, and the poor vocoder just couldn't figure out what was going on.

    I see a couple show stoppers that could keep this technology from reaching critical mass. First this link [kcrg.com] (from the summary) says that one station needed to pay $200,000 to switch to digital equipment. That's a helluva lot of money, especially in light of the fact that radio stations are cutting costs at every turn; and are even canning local DJ's, and replacing them with canned national announcers, to save dough.

    Which brings me to a second point: nearly all radio today is utter crap. The sort of early adapter who would be willing to shell out $400 extra for digital FM is exactly the kind of person who already shelled out $400 for satellite radio. And why would anyone with that kind of discretionary income want to listen to anything on the FM dial? At the risk of sounding terribly elitist, if you're smart enough to have earned gobs of money, your tastes are likely discriminating enough to want to want nothing to do with what's on the FM band.

    The one kind of station that might benefit from high fidelity is NPR, but considering that they're bellyaching for cash every twelve weeks or whatever during pledge drives, this is probably the last type of organization who could cough up the extra dough.

    One reviewer above described IBOC thus: "Let's start with audio quality. It's my opinion that the current 96kb/s codec is incapable of reproducing even a simple male voice without generating objectionable artifacts. It gets worse with music. On the classical cut the strings were thin and harsh. For those of you who are broadcasting contemporary formats, the codec removes sibilance unnaturally, changes the timber of symbols and makes back up vocals strident. This is not CD-quality by a long shot. In fact, during my listening test I found that our station's plain old analog signal sounded better than the 96kb/s codec."

    But wait, if we all stopped unlawfully copying music to our hard drives, perhaps RIAA would stop trying to reclaim the lost revenues from other sources (read: increasing radio royalties), which would in turn allow the radio stations to reduce the ad content to bearable levels. (Okay, so the royalties aren't likely to come down in the near future, but no need to drive them higher...)

    Or alternatively you could go with satelite radio, but that has subscription costs, because they don't have commercials, but the subscription costs are pretty high, because they have to pay those same royalties, because RIAA perceives that they are losing money to our hard drives.

    So, before you pan radio for the problems, think about how much you have contributed to the sources of those problems.

      Amazing that this nonsense is being moderated as Insightful. Where's the insight? I can't find it amongst the ridiculous assumptions, like how we're "all" "unlawfully copying music to our hard drives" and how radio stations would "reduce the ad content" (it's always so likely that a business will decline a revenue source!) if we contribute more directly to the RIAA's coffers, and that I have "contributed to the sources of [radio's] problems." What a load of bunk.

    invented? thats a strong word. patented [uspto.gov] may be closer to reality. I havent gone through each patent but its likely that only iBiquity can say who makes these new HD-FM radios.

    If the FCC is going to be blessing a new standard for radio, it should be a free and patent unencumbered standard.

    Not that more bandwidth is bad, but the real excitement in radio these days is new ways to use it, more features.

    For example, since it's so easy and cheap to do, why not a car radio with Tivo like functions:

    a) Recording multiple stations at once, letting me switch among the recordings, FF, pause and rewind among them. Heck, with software radio record _all_ the stations, all the time.

    b) Know the local traffic stations (ie. traffic every 10 minutes on the 8s) and record that slot and give it to me at the touch of a button, or better still just tune in some digital traffic service that will tell me only of my route.

    Ditto the news, always record the latest newscast, let me hear it any time I want.

    c) Of course let me pause and resume. Also record my favourite talk shows (NPR for example) like Tivo, and let me play them.

    d) Have a speech interface so I don't have to look at the radio to select programs or tune it or otherwise control it! Just give me a little wheel or 4-way control on the wheel similar to what MP3 players have.

    e) And of course, what I am now playing with is using an MP3 jukebox to forget about radio entirely, exept for news, traffic and weather.
    I download NPR programs into the jukebox to listen to them. I can even record Morning Edition in the early morning and listen to it in the morning commute, except with FF and pause etc.

    Plus of course, music, which Mp3 jukeboxes do just great.

    f) Speaking of radio, put 802.11 in the car MP3 player so when it notices it is parked in the driveway, it syncs up my latest music and audio.

    More bandwidth is of course nice, but boring.
    Think about cool features.

    It doesn't appear that anybody cares! And I'm not surprised; I don't care either. Sure, the idea might be somewhat cool, but the slashdot crowd has evolved along with the rest of the world out of the dot-com era where "cool new technology" was assumed to translate into something that will improve our lives. Just as nobody orders groceries through a web site, nobody turns on their FM radio for good entertainment anymore.

    My morning commute is 20 minutes long, and I don't want to spend 12 of those minutes listening to advertisements. I don't care what American media says, I don't need to purchase products to be happy. I don't need a new SUV (or a used one, for that matter) and tonight I won't be tuning into the latest episode of Fox's newest, most outrageous reality series that everyone will be talking about tomorrow. My morning commute is where I clear my head and prepare to deal with the onslaught of crap that I'll face at work. For that, the Dodge Durango jingle just won't work - sorry, but I need <insert your favorite band here>.*

    This is a solution to the wrong problem. We're not concerned with the quality of the FM radio feed, we're concerned with the idiots sending out the signal! This move is just a diversionary tactic that will result in crisp, clear crap. If I ever get tired of listening to my own albums, I'll be looking towards XM or Sirius.

    *I hate when people name-drop their favorite obscure band in an attempt to show off how cool they are. Just pretend I mentioned your favorite musician. And I'll pretend that your favorite musician is as cool as mine. :)
