The problem with boffo product demos is that people
might take you seriously. And they might do it long
before you’re sure it’s a product people need or want.
As a case in point, consider Sirius Satellite Radio’s
Backseat TV, introduced this past fall. Sirius, based in
New York City, first demonstrated satellite TV for cars
at the January 2003 Consumer Electronics Show in Las
Vegas. It wasn’t meant to be a real product, just a
conceptual demo. Terry Smith, senior vice president of
engineering for Sirius, says, “We were just flexing our
muscles a bit. We put it on as a technology
demonstration, just to prove that bits are bits and
Sirius could be an entertainment company, not just a
radio company.”
Then some of the automotive companies already
installing Sirius Radio hardware as optional equipment
saw the demos and pushed the company to get the product
into production.
On the face of it, adding video to audio offerings
doesn’t seem like a bad idea. Today, 29 percent of the
115 million households in the United States subscribe to
satellite TV, according to the Consumer Electronics
Association, in Arlington, Va. That’s a tempting market.
Turning a technology demonstration into a commercial
product isn’t always easy. In this case, the first
hurdle was to develop a new modulation scheme. For the
demo, Sirius had temporarily taken several radio
channels off the air and given the TV broadcast all the
bandwidth it needed. But a commercial product would have
to fit into the Sirius network without cannibalizing the
radio channels quite so gluttonously, and without making
it impossible for existing satellite radio units to
continue to receive the company’s audio programming.
The engineers of Sirius’s Advanced Development Team in
Lawrenceville, N.J., got to work. Enthusiastic about the
product, the company announced in January 2005 that it
would launch Sirius TV in 2006. That didn’t happen. “The
PR got out in front of our technology a little bit,”
Smith says.
But the engineers really rose to the occasion. They
developed an impressive new transmission technology that
breaks up the video signal and combines chunks of it
with each of the more than 130 radio channels that fill
Sirius’s allocated 12.5 megahertz of spectrum. Existing
radio receivers screen out that signal as noise, but the
new TV receivers recognize the signal as data and decode it.
This is an implementation of a transmission technique
called hierarchical modulation, in which two streams of
data are sent at a given frequency; one is given a high
priority—in this case, the radio programming—the
other, the pieces of video data, are assigned a lower
priority. Sirius’s new signal carries enough data for
three TV channels at a resolution that looks fine on an
8-inch-diagonal screen. (Sirius won’t say what the exact
resolution is.) And it has some bandwidth left over for
additional applications that have yet to be determined
but may include data services.
To squeeze the video into a package small enough to be
transmitted on top of the radio channels without
affecting their reception, Sirius engineers chose the
H.264 standard for video compression but tweaked
it—exactly how they changed it is proprietary. H.264 was
the obvious choice. It’s part of the MPEG-4 suite of
standards, it’s in blue-laser DVD systems, and it’s used
in Norway for digital TV broadcasts. A host of other
countries are including the standard in their digital
broadcast plans.
The engineers also beefed up Sirius’s existing
error-correction software to reduce dropouts and
designed the system to use two antennas—one attached to
the front of the vehicle and the other to the rear—to
improve the system’s chances of picking up the satellite
signal. The team also developed a chip that implements
this technology, which is being fabricated by
STMicroelectronics, headquartered in Geneva. The Delphi
Electronics and Safety Division of Delphi Corp., in
Troy, Mich., designed and manufactures the receiver
hardware.
Sirius signed agreements to rebroadcast the
programming of three child-oriented TV channels—Cartoon
Network, Disney Channel, and Nickelodeon. The service,
now called Backseat TV, launched late last year. It
debuts in 2008 Chrysler Town & Country and Dodge
Grand Caravan minivans (with more car models in the
pipeline) and is sold through electronics retailers as
an aftermarket add-on. A Backseat TV add-on to
Chrysler’s rear-seat entertainment system costs US $470;
the whole package, including two DVD players, two 8-inch
video screens, a rear backup camera, and a one-year
subscription to Sirius Radio and TV, costs $2020 for
high-end models of the minivans (in which some features
are already standard), more for less expensive models.
In retail stores, a Sirius Backseat TV receiver, without
a subscription, lists at $300. The subscription price is
$7 per month, added to the $12.95 Sirius Radio
subscription; you can’t get a Backseat TV subscription
by itself.
What the Experts Say
“Low-bandwidth satellite-video-subscription
services with a small demographic, few channels, and
high initial cost seem doomed to failure. On the bright
side, adding video to satellite radio will permit
measurement of whether losses escalate linearly or are a
function of broadcast bandwidth.” —Nick Tredennick
The engineers at Sirius are delighted to see their
muscle flexing become a real product. “To be able to
provide a whole new range of service on top of an
already deployed consumer electronics product is really
cool,” Sirius’s Smith says. “If you look at the amount
of technology we developed, what it took to get that
technology into silicon, and all the quality gates that
the automotive industry requires you go through, I think
we’ve turned this around in an impressive time.”
The initial customer response seems positive, if
mildly so. Mike Kane, Chrysler’s director of advanced
technology strategy, says that 20 percent of the Town
& Country minivans now rolling off the assembly line
have Backseat TV installed; for comparison, about 35
percent of buyers have purchased the DVD-only
entertainment system in the past. But for soccer moms,
the product’s main audience, Backseat TV ain’t the only
game in town. And Backseat TV doesn’t appear to be the
game soccer moms want to play. In fact, some seem
downright hostile.
“If it were free and came standard, I’d pay to have it
taken out!” huffs Catherine McNiel, a mom in Glendale
Heights, Ill. Adds Alma Klein, a mother and advertising
executive in Oak Park, Ill.: “I can only imagine how
annoying it would be to pull into the supermarket
parking lot only to hear, ‘No, don’t turn the car off,
my program’s still on!’ ” [Click here for .]
Industry observers acknowledge that with so many ways
to get video in the car—portable game consoles, iPods,
laptops, and some cellphones, in addition to
DVDs—consumers are not going to be clamoring for this product.
Says James McQuivey, an analyst with Forrester
Research, Cambridge, Mass.: “The future of video in the
automobile is on-demand; it isn’t broadcast. Broadcast
may be a temporary blip, but eventually you will have
what you want to watch in your car when you want to
watch it, whether it comes by shiny disk or iPod or
wireless connection. You won’t be watching whatever
someone is willing to broadcast to you.”
Thilo Koslowski, lead automotive analyst and a vice
president with Stamford, Conn.–based Gartner, does not
see Backseat TV as a compelling product in a world with
many on-demand video options. But Koslowski commends
Sirius for innovating, because innovation in satellite
radio has been a pretty rare commodity for a while.
He says, it would have been a really bad idea for the
company to pull the plug on the project after talking
about it for so long. And Sirius did prove that, indeed,
even far-out demos can come true.
