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.

In particular

    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".

Does a video count as "photographs"?
