          (was "Question for Skip Pizzi")

Like Bruno Guglielminetti I am also very curious regarding how PC
platforms may be used in the future as flexible foundations for the
reception and retrieval of the variety of Digital Radio formats now
emerging internationally for both satellite and terrestrial delivery.

Also how might such a platform may be able to accommodate future
enhancements to say the EU 147 and other systems to increase program
capacity via the application of AAC; PAC; or other advanced systems
of audio coding that will inevitably emerge, as a way of extracting
the most from the limited and valuable spectrum resources available
for Digital Radio delivery in a manner transparent to the consumer.

I am closely involved with the technical planning work for the
introduction of Digital Radio in Australia via Government established
Committees on behalf of Australian Radio Broadcasters, and it is
clear that when we are planning for a system which will not become
popular for probably many years, we need to consider all avenues of
"future proofing" the system if this is practical and hopefully
economical..

Thinking beyond the traditional "hardware only solutions" seems like
a prudent way to approach planning in my view, so I would be very
interested in opening up discussion on these possibilities further
within Radio L.
