Don't confuse the DAB IP telly stuff from BT Movio with proper telly
over DAB. That standard is called T-DMB and it's excellent quality.
It's in use in various places, including South Korea. The cold, dead
hand of Microsoft goes nowhere near T-DMB.
DVB-H is fine, as long as you don't mind waiting ten seconds to change
channels (!!!) or waiting until 2011 for the frequencies to be freed
up in the UK.
Given that DAB is not dying (don't confuse one radio group's short-
sighted business problems with a death of the medium), it would make
rather more sense to continue investing in its infrastructure.

Thanks for the links.
The speech made me think ... if DVB-H gets adopted and used, which
seems likely, it would probably be better to dump the whole DAB (and
even DAB+) idea and use DVB-H instead.
DVB-H's design has the datastream formatted with information that
allows the reciever to turn off for those moments where the data is
not required for a particular channel. Computed by the broadcast
end, the design allows for the receiver to be powered off for over
95% of the time. This certainly would extend the life of any device
that uses it.
Comparing the quality of the DVB-H system I saw in London in June
2006 to the awful service on Virgin DAB-TV (why oh why did the BBC
take part?), DVB-H seems like a "proper" service.

So, can we pull another Freeview style rescue here? BBC+DVB-
H=future relevance !
Also, would be a perfect fill-in for people who can't get Freeview
after switchover because they have to use a portable set or aerial...
Also Commissioner Reding's speech I alluded to in the DRM thread the
other day discusses this:
