Which idents did it use?

It used all the old BBC HD idents as well as using all of its trailers, slides and DOG. No times were given on the trailers, just stating that each programme was "On Board, On TV, On BBC HD".

Also interestingly was that EastEnders was broadcast in a filmic style fading to black between scenes. I suppose it's edited in this way for particular international audiences? But did give quite a different feel to it.

By ‘old’ do you mean the original gemstones set? Or the 2009 idents with the different scenes viewed through the HD diamond? Were the idents clean or did they have announcements?

I suspect the EastEnders fades might be for foreign broadcasters to insert ads where they see fit. The filmic style is probably for the benefit of countries that don’t broadcast at 25/50fps like we do.
