In addition, the Trust also agreed an extension of daily hours on the existing, dedicated BBC HD channel from an average of nine hours to 12 hours a day. These changes are reflected in amended service licences for BBC One and the BBC HD channel, published today.

BBC Trust Chairman Sir Michael Lyons said:

"The launch of a high definition simulcast of BBC One is great news for audiences. As we move towards digital switchover, this is a high-profile commitment to the provision of HD services, which will help to fulfil the BBC's public purpose of delivering to the public the benefit of new technologies. And this is possible within existing channel budgets, meaning excellent value for licence fee payers."

In taking this decision, the Trust took careful account of the implications of the proposals, including noting that adverse impact on other broadcasters was likely to be minimal, that neither change represents a new area of activity for the BBC, and that the changes can be made within the agreed budget range for each channel.

Despite the overall benefits of a universally available HD simulcast of BBC One for audiences, the Trust also recognised that technical and financial constraints currently prevent additional variations, and asked the BBC Executive to take steps to minimise the effects of this on viewers in the nations and regions.

Ends.
