IP + Radio – On a knife-edge between triumph and disaster 21/12/2008

There’s been lots more coverage recently of “WiFi” Radios; radios which stream via the Internet rather than picking up a broadcast signal (FM/AM/DAB). Consumers seem to be enthusiastic about them, and media coverage reflects that enthusiasm.

As it seems impossible for anyone in media to avoid making comparisons, often there’s a line somewhere in the article about DAB being “in trouble”, and that “experts are predicting that internet streaming will over take DAB”.

That would be a disaster for the radio industry, and one that’s avoidable. But more on that in a second.

It’s understandable that consumers are enthusiastic about IP-connected radios. It would appear that consumers are highly motivated to seek out choice in their radio listening, which suggests that they’re not getting that choice now. It’s also pretty clear that regardless of whatever leaps forward in technology occur, people like listening to radio on devices, not on computers. They want something radio-like, and aren’t yet ready to converge on a single-handheld media device.

DAB has delivered that choice in the past, but for a variety of complex reasons, stations have come off the platform, leaving it offering little differentiation against analogue. So if consumers are disappointed by choice on analogue, they’re unlikely to be thrilled by turning on their new DAB radio. That’s something the radio industry could fix, but the barriers at the moment are largely commercial and contractual, as well as a bit of ideology as well.

So if IP-connected devices offer the choice that consumers apparently want, isn’t it the future we should promote?

Firstly, let’s check in on that assumption of choice. We know, even in the analogue domain, that much of it is perception. Media platforms are often promoted and compared on a straight “number of channels” basis; only recently has the relatively saturated market of multi-channel TV opened up a new front on “quality” with the promotion of HD. (I find it ironic that DAB went the other way around – maybe we’ll come full circle with high-quality audio once again becoming something to attract mass-market consumers rather than just connoisseurs?). But even with this amazing choice, consumers tend to gravitate towards a small number of stations. RAJAR tells us that the average listener listens to about 3.2 stations a week, roughly 25% of what’s available to them in the typical British city. The growth in number of commercial radio stations in the last decade (many of which now seem to be unsustainable) hasn’t grown commercial market share, time spent listening, nor particularly the total stations listened to figure. So it would appear that so far choice hasn’t grown listening, and therefore hasn’t grown the total revenue coming to the radio industry.

But how much choice do consumers need, and how must does it cost?

Here’s where it gets dangerous for existing radio companies. Offer too little choice (on FM/AM/DAB) and consumers will seek out the IP-connected alternative. Once they have a IP-connected radio, we have to be on it. Allow that platform to grow too much, and we’ve got a cost and competition headache that will make whatever issues with DAB look trivial. As a defence (and referring to the eponymous “long tail model”) it should be able to produce reasonable choice at low-cost on DAB, which might be sufficient to keep the demand for IP services in check.

If IP is the future, why have no existing broadcasters committed to it as their sole digital platform?

The difference between the “experts” quoted in the media and the established broadcasters is knowledge. Broadcasters have the current and forecast data on their audience sizes, the infrastructure costs for supporting that listening on IP, and the existing relationships with the IP networks. When you start modelling costs, they are breathtaking. The radio industry might end up spending ten times more on transmission than it does now. For a small start-up like Last.fm or Pandora (and yes, they are small), having 50-60% of their costs as distribution is probably OK. But for the mainstream, it would be suicide. You also have to consider the effects of introducing to the picture a whole new array of gatekeepers sitting between broadcasters and listeners, looking to make some money. Net Neutrality is going to be a real battle ground in the future.

(At this point, the “experts” usually start going on about multicast solutions and so on. As far as I’m aware, multicast has been technically possible for 10 years. But the reality is that it is so fiendishly difficult to implement multi-cast AND Quality of Service as a pair, across diverse networks, knowing that every single intermediate router needs to properly support both, nobody is seriously considering it on the public Internet).

If the detailed numbers on current streaming volumes were published, people would be staggered. “Experts” would look rather silly. RAJAR gives us a hint now, saying that only 2% of listening is streamed – that’s about 20m hours a week. And most of that is to the BBC. Despite 60% availability of broadband in homes and offices, internet streaming is still tiny. But the widespread perception, even in the radio industry, is that IP streaming is bigger than DAB.

The radio industry needs to avoid IP streaming becoming the sole standard for accessing radio.

The costs of IP would make the mass-market radio model economically impossibly; doubly so in the mobile space. The growth in IP-connected devices would help new entrants like last.fm and Pandora reach the mass-market at speed, and further erode time spent listening. Consumers would end up paying to listen to radio, either directly or indirectly. Maybe that is the future, maybe that’s what people want. But should we accelerate it by forcing consumers into the IP domain to get choice?

IP is an ideal technology partner for broadcast radio.

“Experts” seem to love pitching technologies against each other. IP is better than DAB. WiMax will trump everything. DVB-H will create world peace and bring fresh-water to the thirsty. Etc. They seem to think that one technology will eventually do everything, making all others irrelevant. But I don’t see them advising the use of a 2kg hammer to put a screw into timber.

IP is a great technology for radio if it’s used for what it’s best at. Let’s use IP for delivering personalised advertising, capturing interest in things people hear on the radio, lightweight mobile interaction, on-demand, super-niche and personalised audio services. Broadcast (DAB) is excellent for the heavy lifting, delivering masses of streams reliably and in a timely manner, across wide areas at low costs (both for broadcasters and consumers). The two are complimentary, like screwdrivers and hammers. You need both in your toolkit. We need converged radios, not IP-only radios.

The radio industry should avoid getting trapped in a world where consumers expect radio solely via IP. It’s in our power to incentivise people to buy radios that support an intelligent convergence of broadcast and IP, and not IP alone. The economic incentive for existing radio broadcasters is survival. It doesn’t get clearer than that.

Internet Media Device Alliance 19/12/2008

Streaming radio has been around for a long time, and it’s a popular activity. The latest RAJAR “MIDAS” survey shows that 31.7% of the adult population in the UK has listened to the radio via the Internet. As the workplace has evolved, the picture of the workshop tranny has been replaced by PCs and discrete bud headphones.

As with any technology, there’s now a wide range of ways to stream radio. There’s different formats (MP3, Windows Media, Real, HE AAC), different transports (HTTP, RTSP, MMS), and no agreed way to list a radio station, or describe its streams.

That wasn’t necessarily a problem when people listened on PCs, and went via the radio station’s own website to access the stream. Missing codecs were downloaded, players could be installed, and with a bit of persistence, you could get most things to play. (Although the BBC really got it in the ear for being such an early and long-standing devotee of RealPlayer).

But all the evidence is that people like listening to radio on, well, a radio. DAB is in half as many homes as have broadband internet, but gets five times more listening. The PC is conspicously not forming the centre of our entertainment universe, for various reasons.

Streaming devices have existed for a while. Do you remember the Philips Streamium? There’s certainly interest to buy connected devices, and that interest is growing as prices fall.

The problem is that putting new codecs and transport support on a hardware device in the field (possibly literally) is not trivial. Hardware devices are not like PCs (thank heavens), and need to work within more clearly defined parameters.

Which is why standardisation would be a good thing.

The IMDA (Internet Media Device Alliance) is a collaboration of manufacturers and broadcasters who are going to make using a streaming media device as simple and consistent as possible. Something a consumer can pick up and use within minutes.

It’s going to involve some compromises, and some tough discussion. It simply isn’t possible to support everything in a sub £100 streaming device. Some limits will have to be set that exclude some existing devices and broadcasters. Not everyone will get exactly the functionality that they need.

But the prospects for broadcasters are very good. We’ll have a clear idea of what formats, transports and bit-rates we should be using. It will mean a way of consistently advertising our stream-locations, programme schedules, live and on-demand content. We’ll be able to provide visual information and simple interactivity to a standard, rather than having to tailor everything on a device-by-device basis (as is the nightmare in the mobile space, due to the somewhat patchy adherence to behaviours by certain manufacturers).

You can find out a bit more about IMDA at the website. If you’re a broadcaster or a manufacturer, do get involved, because this is another great opportunity to Agree on Technology, Compete on Content.


Conferenced Out? You need fast acting RATE! 28/10/2008

Autumn is certainly the conference season. If you’ve trooped round Le Radio, NAB Europe and The Digital Radio Show, all in the last week, you’re probably feeling like you’ve had enough death by powerpoint, and thinly disguised sales pitches for “strategic consultancy”.

But let me encourage you to come to a conference with a difference. Well, many differences in fact.

Radio At The Edge (RATE) is the radio conference which looks at how technology is changing the business of radio today, and what the leading-edge trends are that we could be exploiting in the coming year(s). This is where we discuss the new world order, whether the new world order has in fact already collapsed in a heap, and if the new world order is a complete load of rubbish and we should all go back to sending status updates as smoke signals and poking using sharp sticks. And leave tweeting up to birds.

So it’s not your normal, dull, play-16-songs-in-a-row-and-have-nice-jingles type radio conference.

It’s also darned good value as radio conferences go. £200 for a day’s worth of high value information, and a fair amount of entertainment too. With names like Iain Lee, Richard Herring, Andrew Collins, you’d pay for the comedy alone – if it wasn’t also that the bill includes the world’s most tech-literate reporter and prolific blogger, Rory Cellan-Jones, Peter Davies (Head of Radio from OFCOM), and Leo Laporte – Chief TWiT.

Lastly, there’s drinking at the end, and drinking in a proper pub, with proper beer – not a god-awful overpriced chain hotel dribbling sad pints of generic beer at a crowded bar staffed by communication-challenged staff. Did I mention I’d been to NAB Europe this week?

So I can’t recommend it enough, other than to say you should probably attend for the novelty of being at a conference on radio’s future that I’m not talking at – but my good colleague Robin Pembrooke most certainly is.

No More Channel 4 DAB 11/10/2008

Filed under: dab digital radio — Nick Piggott @ 11:51

Channel 4 Television Headquarters, Richard Rogers Development by .Martin. @ flickr

There has been a tidal wave of reporting, comment and speculation today about Channel 4’s decision not to become a radio broadcaster. The implications of their decision came through in two parts. Initially, it became clear that Channel 4 were pulling out of 4 Digital Group, which effectively dealt a death blow to the national multiplex licence that the group (which also included Bauer and UBC) had won in summer last year. Then, later, there was confirmation that Channel 4 would be scrapping its radio division entirely, ending the possibility that one or more of Channel 4’s stations might end up on the DigitalOne multiplex. There has been substantial amounts of speculation and comment regarding the discussions between DigitalOne, Channel 4 and OFCOM, and the issues are so complex, it’s hard to see how any of it could be entirely accurate.

The news that Channel 4 won’t be participating in DAB Digital Radio is, of course, not great. But Andy Duncan was careful to point to Channel 4’s own financial difficulties as being a key determiner in their decision, not DAB Digital Radio as a platform. I wonder how much the C4 Board were working out how to justify cuts to their core, established, business (and a certain amount of pleading for government assistance) as the same time they were launching a radio division. I believe Andy when he says that Channel 4 went into this with all good intention, and are just being clobbered by the economic situation. So maybe it’s not “never”, just “not now”. It’s a shame, because they had some good ideas (particularly for data services) – but they don’t have the monopoly on those.

Some of the current doom-mongering is happening because so much expectation was heaped upon Channel 4. If it became perceived wisdom that Channel 4 would invigorate the Digital Radio business, then clearly a “no show” tends to suggest the opposite. But I would disagree; indeed, some projects in DAB have been held back waiting for the outcome of the Channel 4 / Second National Multiplex story. There are now fewer unknowns to deal with, which hopefully makes decision making on re-inventing DAB somewhat clearer.

In my opinion, not building a second national digital network is a very good thing for the radio industry. The last thing the industry needed now is to be facing another long-term and expensive commitment to transmission infrastructure; infrastructure that would provide capacity that currently isn’t needed. Remember that the second national multiplex licence sprang into life (well, “was slowly conceived”) when DigitalOne was full and getting fuller. But we have capacity now – both on DigitalOne, and on local and regional multiplexes.

There are other benefits too. DAB in the UK needs a shake up, and one that (hopefully) the right combination of DRWG, OFCOM and the broadcasters will give it. To make really effective (and necessary) changes requires as clean a sheet a possible, and it would have been awkward to have a D2 multiplex just a few years into its existence whilst all the other multiplex licences reach potentially useful breakpoints (both in their licence terms and their infrastructure contracts). If DRWG recommends replanning, there’s no easier time to do it. Similarly, at some point we will need to look at the opportunities that DAB+ might bring to us.

Radio is suffering at the moment. Small stations are struggling to stay above water, and everyone is feeling the impact of a turbulent economy. Channel 4’s arrival might have stimulated some renewed interest in radio advertising, but in the short term they probably would have been grabbing revenue off other broadcasters, and doing that in lean times is hard on everyone.

When reading the doom-and-gloom headlines, and some of the melo-dramatic reporting (and “commentary”), it’s easy to lose track of the fact that DAB is a pretty good consumer story. In the four years since 2004 we’ve moved household penetration from 3% to 27%, and receiver costs have dropped to sub £20. (Admittedly, the 5 years before that were pretty dud). DAB accounts for 11% of radio listening, which means it’s underpinning about £60m of revenue for commercial radio.

The threats to DAB are understood and fixable. There are no problems that are insurmountable, and no threats outside the control of the UK radio industry. No other technology has suddenly appeared that makes DAB look irrelevant. Most people believe that the decision (if there is one) is whether radio stays analogue or goes digital using DAB – I don’t hear anyone seriously postulating using an alternate digital technology.

I’m reconciled to the fact that there’s going to be lots of negative commentary about DAB over the coming weeks, and a lot of it won’t be very accurate. Channel 4 not committing to DAB at this stage won’t kill it, but when the dust has settled, it might just make it stronger.

Standardising the standards – why DAB Digital Radio profiles became essential 01/10/2008

Filed under: DMB, dab digital radio, radio, technology — Nick Piggott @ 05:00

DAB Digital Radio Receivers Lineup (C) DRDB 2008

The Eureka 147 project, from which DAB Digital Radio was born, bequeathed us a very feature rich, powerful and flexible multi-media broadcasting platform, neatly optimised for small, mobile, battery powered receivers. In fact, as a piece of technology, the core EN 300 401 spec and its associated standards (EN 302 077 etc.) are often imitated and are hard to beat. For mass-market radio broadcasting, I believe it is an unbeatable technology.

The core standards were written as a pan-European project to create a digitisation path for radio; an early example of Agree on Technology, Compete on Content. Whilst there are daft things in there (over 10 categorisations of speech programming, only 2 categorisations of “Pop” and “Rock” music), the core has been on-air since 1995, and remains virtually unchanged.

Being fine technologists, the original specification writers left lots of hooks and places to extend the specification. That’s why DAB has so easily incorporated DAB+ and DMB (Mobile TV), and spawned a myriad of interesting data applications – Slideshow, Broadcast Website, EPG, TPEG, IP over DAB (to name but a few). Whatever problem you have to solve, EN 300 401 provides a pretty good starting point. Without over-simplifying things, if you can write packet-orientated IP applications, you can probably write applns for DAB too.

But somewhere along the way, the community lost track of the real reason to Agree on Technology – and it’s receivers. It’s all very well writing the coolest ever DAB application, but what if nothing can receive it? E P I C F A I L…..

I’ve grumbled enough about the individual nations of Europe (and elsewhere) tinkering around without thinking about the implications of their actions. Nuff said.

The outcome was that too many manufacturers, particularly the automotive manufacturers, just found it too confusing and risky to build receivers. Last time I looked, there were three different audio transmission systems, three different ways of visualising radio, two ways of adding browseable content, two ways of transmitting text information, two ways of downloading Java apps to the receiver, and nobody seems to have agreed completely yet how to transmit traffic and travel information. Not only were receiver manufacturers confused about what to support in their devices, broadcasters and regulators couldn’t decide what to do either.

In an attempt to get some direction back into the matter, WorldDMB have produced (after due consultation with the relevant stakeholders) a set of standard receiver profiles, which attempt to balance functionality, complexity and cost, whilst retaining a goal of European-wide interoperability.

  • The Profile 1 receiver is pretty simple – audio (all three types), simple text display. The Profile 1 receiver is the market entry receiver that demonstrates that DAB Digital Radio is a mass market technology anyone can afford. I would hope to see €15,- receivers available Europe-wide within 5 years.
  • The Profile 2 receiver is, in my opinion, where it’s at – or more precisely, where the money is at for the broadcasters. Profile 2 requires a colour screen and supports simple visualisation (amongst other things). If Profile 1 is analogue radio made digital, Profile 2 is proper digital radio. Profile 2 ought to be attainable by all “radio” manufacturers, and Profile 2 (automotive) has to be a slam dunk when you see what people like Audi have in store for our cars.
  • The Profile 3 receiver will probably never get built. Seriously. Profile 3 is the all-singing-all-dancing-it-does-everything-the-licensing-costs-will-be-horrendous profile. What I expect will happen is that a device that already includes pretty much all the relevant technology (and nasty licensing fees) will use Profile 3 to integrate DAB into the device. Think Nokia N-Series, Apple iPhone, Google Android (because I certainly am).

Hopefully by creating some more definite “standard receivers” from the standards, it will enable to confident decision making and commitments. Without it, the market would have stalled in hesitation and uncertainty.

So the ball is back in the court of the broadcasters to broadcast services that consumers will want to buy new radios from manufacturers to receive. That’s natural order of these things. And hopefully, in the future, my colleagues from across Europe will be talking together about how to evolve radio, so that we avoid another clearing-up session in 5 years time.
