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

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."'

Each step took many years, too.

      Even when the progress in the area was, evidently, highly desirable by people. DAB OTOH isn't nearly as attractive - if anything, first versions of DAB were brought to the market too soon, when available codecs weren't very optimal yet (hence quality suffered).

      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.

      2) Mains powered sets are mostly mono (most popular selling type of set). Where is the improvement in technology when you go from stereo to mono, AND pay a premium for it? The stereo versions charge silly money just for an extra speaker. You get better sound out of a 'crappy' boom-box.

      3) Despite being near a transmitter (and line-of-sight so no excuses for reception problems), FM plays flawlessly, DAB likes to break up for no reason.

      4) The amount of compression on DAB should be a scandal, it is ultra low bit rate to get more stations into the multiplexes.

      5) Many _STEREO_ FM stations are in _MONO_ on DAB, all to squeeze more stations into a multiplex.

      6) The error correction for DAB is not very good, it's ancient technology after all. With FM if you have a noisy signal you can open up the radio and change the amount the radio clips off of the FM signal* (some FM radios can do this with a button), but with DAB, you just get a lot of burbling mess for sound, or no sound at all.

      7) The audio CODEC is ancient and does not give good results for the low bit rates the broadcasters are using. Other countries are already switching to DAB+, but the UK doesn't want to change to it, so continue to flog an ancient technology which is not very good.

      So overall, there is no claimed improvement from switching to DAB from FM, like those pushing that dead format claim.

      * IIRC it's before the demodulation stage.... long time since I needed to adjust an FM radio.

You might assert that the 80 or 90 year old hammer I use to pound nails is obsolete compared to modern powered tools for inserting fasteners. But y'know what, the newer tools require power, special fasteners, and are more expensive, more complex and more likely to break. If I were a building contractor, I'd probably use the newer tools (but I'll bet I'd still have and use a hammer). For me that antique hammer is by no means obsolete.

      The only things that would make FM obsolete would be if DAB had better range, lower costs, significantly better audio quality, or some other positive quality. So far as I can tell, it has only one such quality -- less bandwidth. Problem is that most places, there isn't enough programming available to use the additional bandwidth productively and if there were, sub-carrier audio -- which is compatible with analog FM -- could very likely be used instead of DAB. In point of fact, HD-Radio which is the US digital broadcast technology uses digital signals in the sub carrier spectrum while retaining the analog FM signal. (BTW, I don't know anyone who has a HD Radio receiver).

      In summary. Newer isn't necessarily better. And complicated is better only if it works.

The two primary networks in the western part of the region -- Vermont Public Radio and North Country Public Radio in New York adopted quite different approaches. VPR stuck high powered transmitters on top of the biggest hills they could find. NCPR on the other hand decided to use low powered transmitters and repeaters in the small towns of the region.

      Surprisingly perhaps, both systems work pretty well.

      Here's a link to NCPRs coverage map http://www.northcountrypublicradio.org/about/images/cov_map1.jpg and it's transmitter locations. http://www.northcountrypublicradio.org/about/coverage.html

The main transmitter at St Lawrence University is 40KW. I suspect the higher power is mostly to provide coverage to anglophones in the Montreal, QC area.

      Use of high power for FM is by choice, not necessity. And in any case, getting the same coverage for a digital signal is not going to have much in any power superiority -- at least not the way it is currently being approached. Maybe DAB version 5.7a.02 in 2026 will allocate individual channels efficiently and will include receivers that are capable of improving the s/n ratio by narrowing the receiver bandwidth -- which might allow lower transmitter powers. Of course that'll mean yet another iteration of new transmitters and receivers. But what the hell, we're human so continually breaking stuff that is working fine is what we do.

      FWIW, here's the wikipedia on DAB Power "DAB is not a power efficiency transmitting system. Typically an 2500 W DAB transmitter requires 14 000 W of electric power. If two or more transmitter stations are required, the power including cooling will pass 40 000 W. The power efficiency on DAB is therefor around 25-35%, while FM can be as high as up to 90%."

      What you're talking about is the frequency responses, not the dynamic range. Frequency response details the range of frequencies, low to high, the medium provides. Dynamic range is the range of difference between the loudest and softest signals the medium provides.

      Analog FM tends to provide around a 50 - 15kHz frequency response, which while not spectacular, is nothing to sneeze at (especially in the car). That having been said, FM has generally provided craptacular dynamic range for decades now, as broadcasters severely compress the dynamic range of their signals in order to broaden their coverage footprint. By decreasing the dynamic range down to just 10dB or so (as opposed to the 70+ dB afforded by most recording media) they can provide a noise-free signal to listeners over a much broader geographic area. Unfortunately, it sounds like crap.

      Digital broadcasts don't have that limitation - regardless of the dynamic range of the content, you either get the signal or you don't.

    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.

      Sky started with an already established satellite system, but suffered early issues establishing itself against the established, high quality, television networks in the UK.

    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.

    That's also BTW why any possible benefits of DAB are probably irrelevant - people are happy with very few stations already. For anything more there are ways you mention.

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.

  29. Use to program DAB Radios by Anonymous Coward · · Score: 4, Informative

    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.
