DABbed Out

Digital Audio Broadcasting (DAB in the UK, HD Radio in the U.S.) is a technology I have followed off and on for a long time. It has been a couple of years since the last time I posted anything on this blog, and since that time DAB has mostly fizzled, despite making some inroads. Last week, the British tech website The Register reported that the BBC is drawing back its long-term support of implementing DAB as part of its massive cost-containing efforts under the new government’s draconian budget plan.

As in the U.S., part of the problem is the slowness of consumers to adopt the new hardware in the face of constant tumultuous shifting in music playback technologies. The rise of smartphones, the continued impact of the iPod and other portable players, and the success of “cloud-based” listening services have all contributed to a significant shift away from broadcast radio, and one more competing technology has simply gotten lost in the process.

After some quick gains in the U.S. radio broadcasting business, the number of HD stations has plateaued around 2,000, almost all of which are used to simulcast the programming of existing radio stations. Unlike the mandated crossover from analog to digital television, the FCC has not imposed any such crossover for radio, which would drive the necessary sales of receiver hardware among consumers. Some radio ownership companies, including the desiccated corpse of Clear Channel, are beginning to look at using HD Radio services to sell subscription packages similar to satellite radio, offering multiple programming formats over their assorted subsignals. It’s probably too late to do much more than stave off the inevitable, though.

Linkapalooza – Tech

Take a look at your next laptop’s 80GB hard drive. Yes, I said hard drive. Intel has just announced their solid-state hard drive product line beginning with this drive, called the X25-M. You can’t quite tell from this photo, but the form factor is designed around the 2.5-inch width that current laptop arm-and-platter disk drives use. However, it’s only as thick and as heavy as a typical chip-bearing circuit board, which is to say significantly less than traditional disk drives. This model has 80GB of storage, but Intel’s roadmap has 160GB models in the marketplace by early 2009, and smaller models available even sooner. The throughput performance of this drive is better than most current shipping 80GB laptop drives, and Intel claims that the lifespan of the drive should be five years (a complaint about flash-based drives to date has been the relatively small number of read-write cycles, but they claim to have worked around that). Because they are so efficient on I/O, solid-state drives are likely to be very quickly adopted for use in servers, enabling server hardware to shrink even more and reducing the likelihood of server downtime due to mechanical failures.

Now that the XM-Sirius merger is a done deal, the next thing to think about with regard to satellite radio is interoperability. In other words, making it possible for XM radios to receive Sirius signals and vice versa without making all their customers go out and buy new hardware. The FCC has already ruled that any new satellite radio receivers must be interoperable, but now they’ve put out a Notice Of Inquiry to decide whether or not satellite radios must also be interoperable with terrestrial HD radio. Ibiquity, Clear Channel, and NPR have all lobbied the FCC to mandate including HD Radio interoperability, but the FCC would only go so far as to launch the NOI, which starts a somewhat lengthy review process. This is not unlike the deliberations in the 1970s to compel radio makers to include the FM band on every radio; FM radio was the bald-headed stepchild of radio for decades because no one had FM receivers. Once FM popped up alongside AM on car radios, FM stations finally caught on, eventually pushing AM radio into obsolescence. A lesson no doubt everyone involved in this melodrama remembers all too well.

The idea of using bar-code technology with your hand-held communication device has been around for a while, but has only just now turned into an actual service of some kind. USA Today reports that Air France will start letting passengers travelling from Charles de Gaulle Airport in Paris to Schiphol Airport in Amsterdam opt to receive their boarding passes as bar-code images or as text messages on their smartphones. Quite honestly, I don’t think this is such a great idea for airline boarding passes because of the ENORMOUS security risks it poses. Far better that this had been introduced as a service for something with a lot less inherent risk like movie tickets or supermarket deli waiting line numbers. It’s somewhat telling that Air France is only testing it on one route rather than their entire system, and I suspect that this will be slow to roll out, particularly with U.S. air carriers.

DSL Reports says that the number of consumers signing up for DSL service continues to free fall into nothingness. “DSL is the new dial-up” is the catchphrase du-jour in the broadband business as Verizon’s FiOS fiber-optical service has pushed cable companies to be more aggressive with their speed enhancements, leaving pokey ol’ DSL in the dust. According to that linked story, Verizon and AT&T together had a net LOSS of about 120,000 DSL customers in the second fiscal quarter. Anything that keeps the broadband market in the U.S. aiming toward the 100Mbps speed that’s standard in Korea and Japan is okay with me.

I’m not holding my breath, but this story from MuniWireless.com says that Boston is one of the cities where Sprint expects to rollout WiMax as municipal wireless service maybe even before the end of 2008. The rollout is underway right now in Baltimore, with over 1000 wireless access points in the city. Chicago and Washington DC are expected to be launched before the end of the year, and then the next tier of cities includes Philadelphia, Dallas, and The Hub Of The Universe itself. Seems they’ve figured out how to speed up the process of getting the WAPs out into the field so that they can place up to 25 per day, making the rollouts go much faster than originally projected.

A Little DAB’ll Do Ya

Long-time readers know that I have followed developments in the realm of what is called “HD Radio” in the U.S. and “DAB” (Digital Audio Broadcasting” in the U.K. since way back when. DAB has had far greater success in Europe, though it has done reasonably well in large American media markets (Boston, for example, has quite a few stations that broadcast in HD Radio now), In fact, last month, a task force set up by the BBC and other interested parties in the U.K. recommended that all traditional radio services be decommissioned in favor of all-DAB as soon as 2012, but no later than 2020. It’s unclear to me whether or not this might have some impact in the U.S. market; after all, it took nearly 30 years to implement HDTV, and broadcasters are still dragging their feet on that, but the radio business is in a bit more of a state of desperation than the television business.

Meanwhile, British radio maker Roberts has introduced the first solar-powered portable DAB radios in the U.K. (that’s them up there in the picture). (via) Engadget calls them ugly, but I kind of like the neo-retro style. In this country, even though you can find plenty of home HD radio receivers, the thrust of the hardware market has primarily been in the automotive space. Radio listening has been automobile-centric in the U.S. for decades, and is the place where any successor to traditional radio, be it HD or satellite, needs to make its stand. The satellite radio business is still in limbo now that the XM-Sirius merger has been put on hold yet again, so it’s a good time for HD Radio proponents to push for something similar to the U.K. task force recommendations.

Tech News Link Dump

 

Here’s a bunch of unrelated tech news items I’ve been collecting for the last couple of weeks, hoping to get some sort of coherent post out of.

Engadget says that even though Microsoft has extended Windows XP’s shelf life until June 30th of this year (due to flagging sales of Vista and the demand from customers to be able to "upgrade" from Vista to XP), it should still be possible to score a license after that IF you meet a few qualifications.  However, Microsoft is sticking to it’s End-Of-Life date for XP support — April 14, 2009 — AND they’ve been putting out the word that Windows 7, the next version after Vista, won’t be ready until 2011, despite lots of rumors that they would ship it in 2009 to try to overcome the stigma of Vista (it’s really just a Vista follow-on, sort of like Windows 98 SE, and not a whole new iteration).  I think the thing to take away from this news is that if you’re thinking about buying a new computer, do it soon before you’re stuck with Vista…or, better yet, don’t use Windows at all.  Buy a blank PC and choose between several flavors of Linux, Mac OS X (which can now be installed on any Intel-based PC), or even the Linux-based gOS that Wal-Mart installs on their house-brand PCs.

Remember the EyeFi SD card with built-in wireless?  Now they’ve added the ability to sync directly with iPhoto, which should enhance its appeal to Mac users.  I still want it to be able to upload to my home computer via the Internet, so until it does that I’m not likely to buy one myself.

Over the years, I have followed the emergence of HD Radio off and on.  There are now over 1600 HD Radio stations in the U.S.; with three more stations in Boston adding a total of seven HD channels since last year.  There’s still a lot of ground to make up, though, compared with satellite radio.  This recent Wired article says that HD radio receiver sales were only in the "several hundred thousand" range, compared to over 13 million satellite radio receivers.  By comparison, HD radio has done reasonably well in the U.K. (where it is called DAB, "digital audio broadcasting"), where there are 4.7 million DAB radios in use; British DAB users have a wider selection of services to choose from including downloading and purchasing music, programming guides, and the ability to pause/rewind/fast-forward, none of which are available to American consumers.  In Germany, the government-sponsored DAB "experiment" has been de-funded after a 10-year run which only saw two stations adopt the format and 200,000 receivers sold.  Similar lackluster results have been the case in most European countries, which are now waiting for a successor technology called Digital Multimedia Broadcasting (DMB).  DMB, which is already in service in South Korea, carries audio, television, and Internet connectivity on digital terrestrial boradcast signals.

See You On The Radio

A few recent dispatches from the world of radio worth mentioning:

HD radio is beginning to make serious in-roads into many major markets. For example, in the Boston market, there are now 22 stations offering a total of 34 “channels”, where just two years ago there were only a couple.

But HD is small potatoes compared with the booming growth of satellite radio. This Wired article from last week says that there are only a few hundred thousand HD radio receivers in use in the US compared to 13.5 million satellite radio receivers, and even 4.7 million HD radio sets in the UK (where it is called DAB).

The Wired article also points out that in the US, HD radio broadcasters use their sub-bands for multicasting (which is how 22 stations broadcast 34 channels of content), whereas in the UK the BBC and other broadcasters offer a variety of services in addition to the music programming (many of which would face challenges from the RIAA and friends in this country).

Even though satellite radio has the edge at the moment, there is still no guarantee that it will win out over HD radio, which has several advantages including the well-established infrastructure of thousands of radio stations across the country and the value of locally-oriented programming — even though Clear Channel and Inifnity and the like have centralized much of their programming, it would be easy for them to decentralize it if local content proved to win away satellite listeners).

Despite their relative success as noted above, the two satellite services have still not quite lived up to their own projections. For much of 2006, there was speculation that the two would merge into a single service that would have a much larger audience. But late last week the FCC announced that they would not approve of such a deal. In fact, it was specifically disallowed in the 1997 regulation that licensed the two satellite services.
