After a Decade, Digital Radio Still an Also-Ran In UK 200

beschra writes "Digital Audio Broadcast (DAB) was developed as early as 1981. After launching in the UK 10 years ago, only 24% of listeners listen on DAB. The article credits a good part of the delay to the fact that the technology was largely developed under the Europe-wide Eureka 147 research project. How does government vs. commercial development help or hinder acceptance of new technology? From the article: '"If Nokia develops something, they'll be bringing out the handsets before you know it," [analyst Grant Goddard says]. "Because DAB was a pan-European development, you had to have agreement from all sides before you could do anything. That meant progress was extremely slow." But this alone did not account for the hold-up. The sheer complexity of introducing and regulating the system was also a major factor, Mr. Goddard adds."'

        I think reception is a major DAB killer. I live in London, and still can't get a usable DAB signal. The 24% of the country listening on DAB are probably pretty much the 24% who can receive DAB. DAB is a looking like a failed technology at the moment. I use internet radio at home, and there's no real alternative to FM in my car.

      I didn't look too hard, but Argos sells a portable DAB receiver for £20 []. As I said below, the problem is not regulation or standards, but simply that there is no well defined use case for DAB. Other than 'woo, digital!' it isn't actually better than the alternatives in any way. Without that, economies of scale don't push the price down at all because hardly anyone is buying the devices.

          Depends. A clean FM signal is actually pretty good quality, but a clean FM signal is pretty rare. DAB uses 128Kb/s MP2, which is terrible quality. DAB+ uses 64Kb/s AAC+, which is good enough that cheap speakers are going to be the cause of poor quality in a lot of circumstances, but still not actually good. 128KB/s AAC would definitely be better than FM in most cases, but this doesn't seem to be an option for DAB.

              My friend's house is in the country and sits in a natural dip. He can still listen to FM (all be it a little bit hissy at times) on any cheap set without any extra aerials, however he can't listen to DAB at all as he gets about 3 or so seconds of airplay followed by 10 or so seconds of total silence, and this is with a good quality receiver and a roof Ariel.

              He also has similar issues with analogue/digital TV, unfortunately they will be turning off the analogue TV soon, so the only way he will be able to watch TV is with satellite dish and multiple set top boxes so there are no fights amongst his late teen children.

              And also living quite a few miles from his local telephone exchange he can't get ADSL so no broadband internet so that isn't an option either....

              All these things now have a negitive impact on his house value, where as 20 years ago when he bought the place none of these things were important and the isolation was a positive influence on the price.

        There IS a case for what DAB gives you - more radio stations - but that is not a thing specific to DAB. The real problems with the roll-out of DAB stack up as follows:

        1) DAB was promoted as being superior to FM in terms of quality, but then the broadcasters started to tinker with bitrates on order to squeeze as many stations into the available bandwidth, even transmitting some music stations in mono, so that the quality was clearly inferior to FM. This has created a big credibility issue for DAB because the quality angle is still pushed towards an audience that has evidence to the contrary.

        2) DAB reception is patchy in many areas, especially indoors. This may be mitigated when (if?) analogue is switched off and DAB transmissions get more power, but at the moment, for example, I can only receive about 50% of the available stations on my DAB kitchen radio - and if the weather is bad the error rate rockets so all I get is a burble.

        3) DAB reception on public transport, especially trains, is crap. Well-paid city commuters would snap up a decent, working gadget but only AM and FM work well on the move.

        4) The original DAB radios were expensive and also butt-ugly, looking like 'Practical Wireless' projects from the 70s. Many were also mono, with only one speaker - you paid extra for an add-on. These wooden-boxed radios appealed to early adopters and the curious, but the general public were not so enthusiastic. Recent designs are more sensible.

        5) Portable DAB sets - especially the shirt-pocket sized ones - really really eat batteries. I'm lucky to get 4-6 hours out of a pair of good quality alkaline AAA cells. In fact, I have just ordered some 1300mAh AAA rechargeables because the cost to feed the radio with normal cells is stupid - you could easily spend more on cells in 3 weeks than the cost of the radio.

        6) Getting a DAB radio for a car at a sensible price is pretty much impossible - and those who have them don't seem to be impressed with the reception and performance.

        7) The technical spec for DAB is out of date already, but to replace it would mean admitting that the original design was not well thought out AND would force all current adopters to scrap their current kit; and no-one wants to be the one to announce that.

        8) Many people take their own music with them and can pick and choose what they want to listen to. Why swap this for something that sounds worse and doesn't play what you want?

        9) The number of mobile phones with DAB receivers is (I believe) 1 - and it's only available on one mobile network (Virgin). Having a mobile phone with DAB would give the service a *bit* of credibility, but would probably screw up battery life.

        10) Here's the kicker: FM and AM 'just work' and very few have problems with the quality - there is no public tidal wave of protest demanding anything better and this leads to a sense that DAB is being pushed onto the public - which instantly gets people pissed off.

        The current way forward for the broadcasters and politicians seems to be a defensive 'do nothing' while half-heartedly championing DAB, and no doubt there will be some form of mad scramble to do something half-assed when the analogue switch-off dates are imminent. There is an analogue trade-in promotion at the moment and it will be interesting to see what the take-up is.

        Very recently, a Government source stated that the FM switch off would only happen when there was little demand for the service - which is a change from the previous 'rock solid' fixed date, but unless there is some serious push to improve DAB reception and produce a portable set with a sensible battery life, I fear we are going to bump along the 'do nothing' road for a long time.

    You've been able to buy DAB receivers cheaply for ages. Psion used to sell them, and they haven't been around for a while - I remember seeing their DAB receivers for about £20 back in 2001 and now I imagine they're even cheaper. The problem with DAB is not government development, it's that it's a solution with no corresponding problem.

    FM radio is good enough for most people. DAB uses a fairly poor compression system, so doesn't give noticeably better quality than FM (unlike FM versus AM). It requires new equipment, but my father still has the FM receiver he bought in the late '70s - it still works fine and gives good audio quality, so the only reason to upgrade would be if they turned off the FM or if there were radio channels that he could only get on DAB.

    I don't actually own anything that can receive broadcast radio. I listen a lot to Internet radio stations. DAB can't really compete with the available content there - there simply isn't enough bandwidth available to broadcast every Internet radio station. The only advantage DAB had over Internet radio was that it worked while mobile, but the most common place where people listen to the radio while mobile is in cars. DAB receivers in cars are not that common, and DAB reception in a moving vehicle tends to be pretty poor even if they are.

    Now, with mobile phones starting to include data plans, any mobile can stream a 64Kb/s AAC Internet Radio stream from anywhere in the world and get similar sound quality to DAB. DAB uses 128Kb/s MP2, which is pretty poor quality. DAB+ (which requires another equipment upgrade if you bought a DAB receiver) uses 64KB/s AAC+. The radio station that I listen to most often provides 64 and 128KB/s AAC+ streams, so if I am at home I get better quality than DAB, if I listen on a device where bandwidth is more limited then I get the same quality (and, unlike DAB, the non-local station is actually available). Unlike radios, people upgrade their mobile phones every few years, so if a new, better audio CODEC comes out, you can deploy it immediately on the server, watch people slowly switch, and turn off the old one in a few years. When was the last time you saw an Internet Radio station using MP2?

    If Nokia had introduced a digital broadcasting standard, they'd have had devices on the market, but who would have been transmitting? People who bought broadcasting equipment from Nokia? Would the BBC have bought into a single-vendor solution like that? Absolutely not. And if they'd got other companies on board, they'd have needed a similarly long standards process (see WiFi) to get them all to agree and to avoid incompatibilities between implementations.

            The really funny thing is, when they come to sell the FM space, no one will want it as no doubt the pirates will take it over.

            There are millions of FM receivers in this country, and at some point they will all be purposefully obsoleted at once. People will inevitably step up to fill this void, and suddenly the radio waves will be full of stations not wanting to listen to regulators.

Hell, the same stations all over the dial - the other day I was waiting for a mate in the car, and was bored, so skipped through FM 0.1MHz at a time, to see what pirate stations were around. At least 3 different frequencies were exactly the same station, all with different RDS names. And even the independent places all play the same shitty pop-music.

          The UK was quick out of the blocks with widespread DAB deployment and despite the complaints in this story that it hasn't caught up FM, there are many millions of receivers in use which only only support an 80s era codec. Moving to DAB+ codecs will be hard in the UK, and while DAB+ would be more efficient, taking away bandwidth from DAB to broadcast in DAB+ for a cross-over period means reducing the number of broadcast stations. This will upset people who were sold DAB on the basis of the channel choice; witness the recent outcry when the BBC proposed to close the digital-only station 6music.

          The article mentions that 24% of listening is digital; if that were DAB that would be pretty impressive. Unfortunately, in an article about DAB, the BBC is rather lax in the statistics it quotes by not breaking down "digital", which includes DAB plus radio over DVB-T, satellite TV and internet streaming. The last is quite popular with hours spent online streaming BBC radio vastly ahead of the more frequently trumpeted video iPlayer services.

      • Meanwhile, FM radios bought in the '70s still work (and work well).

        Even earlier - my FM tuner was made in the 60s and still works well, it even has stereo (Leak Troughline Stereo). Another radio also works well, but it was made in the USSR where they used a different frequency range for FM (~65-75MHz) so I needed to make a frequency converter. Still, the radio made in 1964 sounds quite good.

        Granted, if the signal is weak I'll hear noise, but I'd rather hear some noise than artifacts produced by the codec, they annoy me more.

    The real problem with DAB isn't price or features. It's battery life. My FM/LW radio lasts over a month of regular use. A similarly sized portable DAB unit manages about 6-8 hours. Why would I 'upgrade'?

    I find the free market plug kinda funny in that instance: if you let the free market decide, you don't get Nokia nor the Euro GSM standard, you get the US mess of incompatible operators and standards, with each company trying to push their agenda, their patent-encumbered techs... How would you like your radio to work in the UK, but not in Ireland ? Or to work on the public channels, but not with some private ones ? Or to work only with tailor-made, more expensive sets ?

      Patents are just another form of regulation. There is no true "free market" when companies can artificially stop competition using lawsuits. Or alternatively, there is just as much free market in Europe, where there is a GSM standard. Regulation either does or doesn't eliminate a free market. You can't have it both ways.

  • When there's spotify, itunes and some slightly less legal services to provide all the music you could want; podcasts to do shows and, if you can stand the news, it's on your phone, your laptop, your tv and probably a load of other devices. It's hard to see what a non interactive audio service offers.
    • Really, people value the non-interactivity, it's a benefit. Sometimes you just want to fill the background with good enough music / etc. while doing something else (I suspect also not wanting something great - not wanting to be hooked too much); with scheduled short news service every hour a nice bonus (also one you don't have to actively follow, but still be certain that important news will reach you)

      This blog post covers it quite nicely []:

      the vast majority of the radio listeners don't listen to music. They hear music instead. There's a difference. They put the kids on the SUV, and drive them to school, and turn on the radio in the meantime. Or, they're stuck in traffic, pissed off, and need to listen to "easy" music to pass the time. Or, they're sitting on their sofa, reading a magazine, and have the radio ON as a background.

      Very few people actually drive somewhere in order to turn on the radio and listen to music. Or sit on their sofa, closing their eyes, and listen to just music. Normal people instead, are so busy with their lives, their problems, the quick pace of this civilization, that simply don't have the time to discover new music. Listening to unknown kind of melodies, or new kinds of sub-genres altogether, takes them out of their comfort zone. Listening to something like Dan Deacon instead of Lady Gaga, for example, while the kids shout at each other at the back of the car, makes it difficult to level your head. Not only you have your problems, but you have this new 'annoying' music playing instead of the music (or kind of music) you already know so well.

      Basically, commercial radio works as a kind of a depressant for the masses. At first, it feels like music is exactly the opposite: an excitement that is, but in reality, in the large scheme of things, as far as FM radio is concerned, it's nothing but one of the ways that helps you kept in check. No, this is not a conspiracy theory, it's just how things work. Listeners want it that way too.

    As many people have already stated, DAB Digital Radio has a plethora of issues.
    The radios themselves aren't that cheap, especially portable ones. There's no real benefit to owning one, you get a couple of extra stations that you probably wont listen to and the reception is terrible in most places. For years, I've wanted the technology to take off and be good, a bit like Freeview OTA Digital TV, but it never happened.
    Now, for me, technology has moved on. I have a pretty decent android phone and use an app called Streamfurious. With this, I can listen to thousands of radio stations from all around the world, including just about every station you'll get on digital radio, in better quality and over 3G as well. It works surprisingly well, less cut outs than I ever did get with DAB.

    I agree with posters above that non-interactivity is good - it reduces cognitive loading, as Bruce Sterling would say. You just want something to tune into, that respects your style of music, stretches your boundaries slightly and gets on with the job in the background. DAB could have been good; however, they failed to move quickly enough to get the receivers out there at prices competitive with FM. It would have to be pretty dang competitive for me, since I have two excellent Home Cinema receivers with FM, a kitchen radio with FM, a bedside alarm clock with FM, a a Hacker Black Knight in the shed, one for when I do DIY and don't mind it getting paint-spattered, several vintage receivers including a bakelite Ecko, one for when I am out flying kites, one in each car ... so anyway before I digress, DAB took too long, so it itself is obsolete against Internet radio, iTunes podcast downloads Sky radio stations and a myriad of other more modern solutions. The Germans are letting it die on the vine also. Why do we not do the Capitalist thing, and let the consumers determine its fate. Oh wait, we already did. LET IT DIE.

    In the UK at least, there was slow take-up of DAB because of all the issues surrounding it at the beginning that the popular press picked up on - namely poor signal coverage, lack of decent car receivers (where I believe the majority of people listen to the radio anyway), and overly compressed streams that made anything but ClassicFM sound awful. There were alternative sources of music and people just wouldn't pay the high costs for little perceived benefit - ie the initial outlay for the receiver, the running costs, and reduced portability.

    Now that the costs have come down, DAB is potentially doomed by switch-off and replacement by DAB+. Many older receivers (many of them were still on sale a few months ago, probably still are) cannot be upgraded to receive this, which has been further highlighted in the press and further puts people of buying.

  • one in four, that's sounds like heavy enough adoption to me, millions of units!!!

  • It's lossy low bitrate audio. The reception is dire and when you have a weak signal you get garbled choppy annoying sound instead of a bit of hiss and crackle.

    Would be better streaming from the internet.

    I don't have reliable stats to hand, but I would be willing to bet most radio listening is done in the car, certainly among younger people. I recently bought a new car (Volkswagen Golf Plus []) and the DAB option was £175! To put this in perspective, the reversing camera costs £165. To put this in perspective, the carpet mats cost £75....hmmm....
  • DAB launched in Canada several years ago. Every radio station participating, which was virtually all of them in Toronto from what I remember, filled the airwaves with ads promoting how amazing it was. I was pretty excited about it.

    There was one problem, however: You couldn't buy a damn receiver for it.

    They had a couple of lousy ones at Radio Shack, and DAB car decks were virtually nonexistent. It was doomed to failure, and it indeed failed. I don't know a single person who ever even had a chance to listen t

    I used to work as a programmer at one of the few British DAB firms, which went bust not that long ago. What really annoys me is all the myths about DAB that are propagated by various journalists.
    Myth 1. FM audio quality is better than DAB at 128kbits. This just isn't true and the only FM station with any quality at all is Radio 3, because the BBC pump massive amounts of power and engineering effort into the signal. The problem is that FM signal degradation creates white noise, which the human brain filters out without even noticing (especially in a speeding car). In contrast all digital audio has to suffer unpleasant squeaks and artefacts if the signal is corrupted. However, under truly equivalent conditions of power the DAB signal trounces the FM quality. Unfortunately, in practice the DAB signal is much nearer the noise floor because: linear broadband transmitters are way more expensive to run than constant power FM transmitters; because the thermal noise in the receiver is proportional to bandwidth and the DAB wavelength doesn't penetrate buildings all that well.
    Myth 2. DAB is failing, because the MPEG2-Layer II codec is old and inefficient compared to MP3 and AAC. Truth is the DAB+ codec is horrible to listen to in practice and the old DAB one is much better for the job of sending over poor signal paths. The higher the compression ratio the longer the encoded audio frames get. With the 24ms audio frame of DAB, losing a frame simply causes the classic 'bubblng mud' sound and some frame repetition can be allowed to pad the gaps in a benign fashion. With AAC+ you get 120ms superframes, which equates to massive silent pauses and repetition sounds like Max Headroom. Certainly the DAB+ standard has reed-solomon to push it even nearer to Shannon's limit of SNR, but in truth most fading that causes problem is brief total signal loss, which long frames actually aggravate. This sort of signal loss happens a lot, because most people put there radios deep indoors and actually have a much worse signal reception than they realise. The end result is with DAB+ radios people start to think the software is on the blink due to the on-off nature of getting audio out of one as you move the aerial about and it is very hard to suss out a good reception spot for the antenna as there is no feedback on signal quality.
    Myth 3. The low bitrate used in DAB is in some way due inefficient coding/transmission. This is simply due to short sighted commercial decisions and basically the broadcasters will always reduce the bitrate till users complain. The commercial networks clearly intend to reduce the 128kbits channels used for DAB to 32kbits and 24kbits when using AAC in DAB+ (see Australian DAB+ tender bids), by which point any quality gains from the codec have been thrown away.

    The real reasons DAB is dying are:
    1. All forms of broadcast are dying due to the rise of on-demand/interactive ways of listening to media. The moment decent MP3 players started to be sold, DAB radio sales were doomed. People mostly want to listen to their own choice of music and whilst news, chat and introducing new music are important most commercial stations just act as a jukebox that you can't control.TV and satellite are going the same way, but are partly saved by the fact that the mobile device form factor cannot provide a decent viewing experience. Decent internet connected smartphones are the final nail in the coffin for the classical broadcasting model and I do wonder who on earth is going to want the TV wavelengths when they are finally freed up.
    2. Digital radio is hard to make portable and low powered. The power requirements for MP3 audio decode are tiny compared to those of capturing, sampling and DSP decoding an 8MHz/s signal to the point where you can start the equivalent of MP3 audio decode. FM can be decoded to an adequate signal with a few non-linear components and provide perfectly adequate audio. The aerial size for DAB is also awkwardly large and a proper dipole is essential for coping with the poor broadcast power used in the

  • Could it be IPOD + ITUNES + Podcasting have made radio the cassette tape player? Satellite (Digital) Radio isn't doing too well either, though cars are throwing in receivers for free. Sirius (recently merged with XM due to financial weakness) extends me $5 per month inducement subscriptions which I ignore. So, cost is not a factor; lack of usefulness is. At home, I use shoutcast etc., for "digital radio".
