Read this: The BBC One HD channel is ready for launch

Summary: High Definition HD from the BBC will take another giant step forward in just a few weeks time. The channel will show exactly the same programmes as BBC One in standard definition, but wherever a programme has been made in HD you will be able to experience it in all its glory. We'll open with The One Show, of course, at 7pm, which shifted to HD this summer. - bbc.co.uk
