Sony Ericsson and Nokia to Co-operate on DVB-H Interoperability

Sony Ericsson and Nokia to Co-operate on DVB-H Interoperability

3GSM WORLD CONGRESS 2006, BARCELONA, Spain and ESPOO, Finland, February 13/PRNewswire-FirstCall/ -- Sony Ericsson and Nokia (NYSE: NOK) today announced their intention to
co-operate to achieve interoperability in DVB-H enabled devices and secure
multivendor mobile TV services and pilots from 2006 onwards. There are going
to be a multitude of technologies that will enable consumers to access
different types of content over mobile phones. Sony Ericsson and Nokia
recognize DVB-H as the preferred technology for terrestrial digital broadcast
mobile TV, with both parties being active in ongoing standardisation and
technology development to enable an improved mobile TV experience for the
consumers.

To secure interoperability in multi-vendor mobile TV service pilots, the
Open Air Interface implementation guidelines, publicly available on the web
(www.nokia.com/mobiletv), will be used. Current and future technologies
within related standardisation bodies will be reflected in future releases of
the OAI implementation guidelines and compatible products.

"Sony Ericsson believes that mobile TV will be a key growth area for the
mobile phone industry in terms of handsets, applications, content and
services. With our unique background in telecommunications and audio visual
technology, we are ideally positioned to take advantage of these new exciting
business opportunities" said Mats Lindoff, Chief Technology Officer, Sony
Ericsson. "We are pleased to announce this co-operation with Nokia on
developing DVB-H interoperability as we believe this will be one of the key
technologies driving the mobile TV market in the future."

"Availability of interoperable DVB-H enabled mobile devices is crucial in
opening up the mass market for broadcast mobile TV," says Ilkka Raiskinen,
Senior Vice President, Multimedia Experiences, Nokia. "We are delighted to
see that the Open Air Interface (OAI) implementation guidelines which we
published in August 2005 can serve as a concrete starting point for
interoperability. We are confident that DVB-H will be the technology that
enables the best broadcast TV experience on mobile devices."

DVB-H technology complements existing operator networks, optimizing
capacity and quality. It offers consumers the chance to enjoy high quality
terrestrial digital broadcasts along with voice telephony and internet access
all in a single device. Broadcast mobile TV will offer new business
opportunities for mobile service providers, content and broadcast companies,
infrastructure and handset manufacturers as well as technology providers.

The feedback from different mobile TV pilots has been promising. The
recent interim results from the Oxford Mobile TV Trial showed that there is
clear consumer demand for the service and that 83% of the pilot participants
are satisfied with the end-to-end service provided.

Notes to Editors:

DVB-H technology enables the TV service you are familiar with at home to
be broadcast to your mobile device. DVB-H provides the best user experience
in the mobile environment with excellent picture and reduced battery
consumption. Up to 50 TV channels can be delivered with low cost, over one
network. With extensive pilots of broadcast mobile TV currently taking place
across the globe, involving leading broadcasters, mobile operators, broadcast
network operators and handset manufacturers, the market for commercial
broadcast services is expected to spread during 2006.

The Open Air Interface (OAI) 1.0 implementation guidelines which Nokia
published in August 2005 are availabe at www.nokia.com/mobiletv. The Open Air
Interface is based on existing DVB-H standards and specifies how mobile TV
devices connect with the DVB-H network and the servers of the overall mobile
TV service infrastructure. The OAI specification was published to enable
multivendor interoperability in the mobile TV industry.
