VT Communications Launches Pioneering DRM 26MHz Service in London

VT Communications continues to push the boundaries of digital radio
broadcasting by launching its dual-channel Digital Radio Mondiale
(DRM) transmission service from Crystal Palace in South East London
into Greater London. Partnering with Deutsche Welle and UBC Classic
Gold VT Communications can now provide two discrete broadcast services
over a single 20KHz transmission band centred at 25.7 MHz. This is the
first time the double channel mode of DRM has been used for extensive
field trials and further enhances VT Communications digital offering.

The 26 MHz band is designated as an international broadcast band, but
is underused and could also be used to provide local "FM" type
coverage. Demand for both FM (88-108 MHz) and DAB (band III) spectrum
in the UK is very high, and DRM could offer broadcasters access to
additional spectrum in addition revitalising existing MF and LF
frequencies with enhanced audio quality.

The ability of the 26 MHz band to provide local and digital radio
coverage adds to VT Communications existing regional and international
DRM capability. In 1999 VT Communications started regular "ITU
compliant" DRM tests from the Rampisham transmitter site in Dorset UK,
to Europe. In 2003 a new high power MF transmitter was added to the
portfolio, which now transmits the BBC World Service in digital
quality to the Benelux countries. In March 2006, VT Communications
announced a significant investment in a new high power HF transmitter
at its Woofferton (Shropshire, UK) transmitter site. This will be
operational by mid 2006.

VT Communications are also investing in a new broadcast centre
designed to distribute audio in a totally digital format from studio
to listener, including distribution of DRM. This will eliminate audio
degradation caused by repeated conversion between analogue and
digital, a surprisingly common problem with digital transmissions. The
broadcast centre will also be able to format & distribute audio via a
number of different routes, including archiving, podcasting, content
repurposing and audio on demand. The 26 MHz service in London will
showcase the broadcast centre technology, as data channels, Electronic
programme guides (EPG) and a 3rd audio service are all scheduled for
test during the course of 2006.

"VT Communications ongoing investment in DRM 26MHz and HF capability
is part of our new Global Media Network" says Bryan Coombes, General
Manager Broadcast at VT Communications. "This underlines our
commitment to provide a digital service to satisfy all of our
customers' broadcasting requirements, from local through to truly
international coverage".
