Some lucky Freeview digital viewers in London will be able to get high-definition TV this summer, thanks to four terrestrial broadcasters in the UK. 500 volunteers in the capital are being sought to test the service, known as DTT HD. Games from the World Cup in Germany will be included.

'This trial will allow us to evaluate the technology and give us valuable insight into viewer attitudes to HD, helping to show the possibilities for HD broadcasts over DTT post-switch-over,' said Simon Fell, the controller of emerging technologies at ITV.
