                           MOBILE TV TRIAL GOES LIVE

Released: 22 September 2005

In a UK first, EastEnders, Coronation Street, CSI and Lost are just some of the
TV programmes up to 400 O2 customers, living and working in Oxford, will be able
to watch live on an advanced mobile phone from next week.

O2 and Arqiva (previously known as NTL Broadcast) have teamed up with Nokia as
well as the leading terrestrial and satellite broadcasters to kick-off the UK's
first trial of full multi-channel mobile TV. 16 channels are being offered to O2
customers, including BBC ONE, BBC TWO, BBC News 24, ITV 1, ITV 2, Channel 4 and
Five, which will provide a core of mainstream channels coupled with programmes
from British Eurosport, Cartoon Network, CNN, Discovery Channel, MTV, ShortsTV,
Sky News, Sky Sports News and Sky Travel.

Customers will be able to select their favourite programme from an on-screen
service guide, search for specific items as well as set their handset to alert
them when a show starts. The trial will run for up to six months and is designed
to test and showcase the televisual capabilities of the next generation mobile
services. It will look at how people choose to catch up on their favourite TV
shows, how they watch the latest music videos and keep up to date with the news
and sport when on the move, and provide an understanding of how much customers
are willing to pay for the service.


The service is based on the new DVB-H (digital video broadcasting - handheld)
transmission standard and works by beaming a signal to a digital TV receiver,
which is attached to Nokia's new 7710 handset, transforming it into a portable
TV. DVB-H is ideally suited to sending high-quality, digital TV pictures from a
single source to multiple users in a way that complements the one-to-one video
streaming which is already possible via today's GPRS and 3G mobile data networks

Dave Williams, O2's chief technology officer, said: "Increasingly, new forms of
content are making their way onto mobile devices - music, in particular, is
already booming - and the latest buzz is about television. There will be many
millions of mobile TV viewers worldwide by 2010.

"As an emerging industry, mobile TV will require a willingness of operators,
regulators, broadcasters and handset suppliers to strike new deals. Regulators
need to licence new spectrum, which will allow global economies to exist,
broadcasters and publishers will need to tackle digital rights issues and
operators develop workable revenue sharing partnerships. By establishing
relationships through activities such as this, we hope that potential challenges
will be minimised and mobile TV becomes a commercial reality sooner than is
currently possible."

Hyacinth Nwana, Arqiva's managing director, mobile media solutions, commented:
"We've pulled together an extremely strong and varied 16-channel line-up,
reflecting the range of content that our original research identified as
desirable for a mobile television service. In Europe all evidence points to
mobile TV being mass market. Oxford will address the critical success factors
such as scalability, consumer experience, content mix and consumer choice."

Mark Selby, Nokia's vice president, multimedia, added: "The Oxford trial is an
important step in the roll out of mobile broadcast TV, building on the recent
successful trial in Helsinki. Consumer reaction and usage patterns will help the
broadcast and mobile industries understand what content viewers want to see on
this exciting new technology. The Oxford trial will add valuable new research
and it will be followed by multiple trials in Europe, Asia and America. Nokia is
pleased to be working with O2, Arqiva and the many content producers
participating in this trial."

In addition to aggregating the content and operating the trial service, Arqiva
is providing the DVB-H transmitter network that will cover an area of 120 sq km
centred on Oxford. O2 customers taking part in the trial do not pay to watch the
TV element of the trial, however all voice and data calls are charged under
their existing tariff plan. Nokia has provided the handsets and is working on a
new range of devices for the future with in-built DVB-H capabilities.
