Don't recognise the clip - but it's highly likely that this is a piece either custom-written for the programme, or an 'off-the-shelf' clip of the type which are made available by a number of studios.
Both sources are popular with programme makers because they are generic, and cheaper to use that commercial pieces, which often demand a large fee and / or royalty payment for use.
The problem is, such pieces are not commercially available, so you will be unable to get a copy of it.
