LONDON: The ruling BBC Trust has given a provisional green light to the state-funded broadcaster's plans for a high definition television channel.

The proposed service, which would initially carry content from the BBC's flagship terrestrial channels and its niche digital offerings, has also received approval from UK media regulator Ofcom.

The Trust - the corporation's twelve-member independent governing body - has now begun a public consultation before delivering its final verdict, due toward the end of November.

If the channel gains approval, a four hour version could be launched immediately via the Freeview platform. However, viewers would need to upgrade their set-top box at a later date to receive the full HD experience following digital switchover.

The service, which is being trialled on cable and satellite, has caused concern among the BBC's commercial competitors which lobbied for the Ofcom investigation.
