Another transition in the making. And for all of those who are fixated
on a single solution, like there can be nothing better, please note
this:
"MacAvock declined to reveal building blocks for the emerging DVB-T2
spec since discussions are still in progress. But he noted, 'We've
re-opened Pandora's box. We're examining everything from spread
spectrum, single carrier systems to more advanced orthogonal frequency
division multiplex for single and multiplexed channels, and even China's
DMB-TH' as possible candidates for DVB-T2."
If what Craig says is true, that the purpose of HDTV was so that
broadcasters could retain their 6 MHz channels even after transmissions
went to digital, then perhaps the similarly cynical purpose of DVB-T2 is
toward the same goal? The returned analog spectrum would once again have
to be recylced for another TV transition? Here's the quote which
suggests this:
"Driving the DVB Group to develop DVB-T2 is the opportunity for
broadcasters to claim new spectrum expected to be freed up after analog
TV broadcasts are switched off to make way for digital TV."

AMSTERDAM, Netherlands - The Digital Video Broadcast (DVB) Group, which
forged terrestrial, satellite and cable digital-TV broadcast standards,
will launch its next-generation terrestrial digital TV broadcast
specification called DVB-T2 by early 2008, according to Peter MacAvock,
executive director of the DVB project.
"There is real rocket science going on" in this area, MacAvock said
Friday (Sept. 7) at International Broadcast Conference. The new standard
"will be a groundbreaking system" rather than "tweaking a few buttons"
on the current DVB-T standard, he added.
MacAvock declined to reveal building blocks for the emerging DVB-T2 spec
since discussions are still in progress. But he noted, "We've re-opened
Pandora's box. We're examining everything from spread spectrum, single
carrier systems to more advanced orthogonal frequency division multiplex
for single and multiplexed channels, and even China's DMB-TH" as
possible candidates for DVB-T2.
Driving the DVB Group to develop DVB-T2 is the opportunity for
broadcasters to claim new spectrum expected to be freed up after analog
TV broadcasts are switched off to make way for digital TV.
The DVB Group wants to give broadcasters "the very best technology that
can exploit a newly freed-up spectrum," MacAvock explained.
DVB-T2 will be designed to co-exist with the current terrestrial DTV
standard, DVB-T. The new standard will enable broadcasters to offer a
variety of new services including "ultra-mobile TV, multimedia channels
and HDTV," said MacAvock.
By building in enough smarts and advanced technologies into the spec,
the DVB Group hopes that DVB-T2 can be pitched to regulators as the best
use of the new spectrum.
The DVB Group will complete the first draft of the DVB-T2 spec in the
first quarter of 2008. Development of consumer products based on the new
standard will start in late 2009 to early 2010, MacAvock predicted.
