The trials, which will be carried out next year, will provide 500 O2 customers with multimedia mobile phones. The phones will have a built-in digital TV receiver and access to 16 TV channels.
The final channel line-up is yet to be confirmed but NTL said it will cover music, sports, news, comedy, soaps, documentary, drama and cartoons, as well as specialist channels, including interactive gaming and shopping.
Terry Howard, head of media business development, NTL broadcast division, said: 'This is a commercial trial to test the business case for a mobile TV service in the UK.' NTL is developing the TV channel portfolio and will operate the transmission network. Sony Semiconductor & Elec-tronic Solutions (SES) and Nokia are also involved in the project.
The trial will be carried out in Oxford.
