I'm not a lawyer, but judging from the wikipedia article, it seems unlikely. This isn't a video of an "event", it's a video describing an event. Sky could have perfectly well made their own video.
Photographs are excluded, however; Cornish, Llewelyn and
Aplin write that this is "in order to preserve the full
value of holding a unique visual record of some person
or event".
I don't think using media created ad-hoc to show how something works is fair use. It's like Fox News showing footage from National Geographic (without paying)

In particular
Does a video count as "photographs"?
