Terrestrial HDTV trial planned for summer

The BBC, ITV, Channel 4 and Five have confirmed plans to test a terrestrial HDTV service in the capital.
Around 450 households with HD Ready sets are being sought to take part in the trial; the broadcasters are partnering with TNS to seek potential participants.
The trials will utilise a frequency not available to commercial broadcasters, and the signal will be transmitted at low power. The test service will only be receivable within a region bordered by the North and South Circular roads.
Programmes to be carried on the test service include live World Cup coverage from the BBC and ITV.
A press release from the BBC explained: "The DTT HD trial will be a closed technical test available only to the triallists. Londoners with Freeview boxes will see the test channels listed in their onscreen menu, but will not be able to access them. The DTT trial will enable the broadcasters to test technical delivery of HD on Freeview and to understand how the audience values HD programming."
"London has been chosen for the trial because a low power HD signal there will reach many homes, reaching many potential triallists, without interfering with existing broadcasts. The test signal will use a frequency which is not available for commercial broadcasting. Freeview has no capacity for more national networks, and will not have enough room for national high definition broadcasts until at least switchover when existing analogue signals are switched off."
