I'd like to see how any challenge would play out in court.

You'd have the King basically suing to block his subjects from watching a repeat of his mother's - their Queen's - funeral.

I would suggest that as the event was of significant historical importance, and as it was a "State" event, the footage would therefore become default ownership of the state.

That said, if the Royals want royalties out of it, or want to limit access to it for other reasons, the Treasury should be knocking up the bill for all the pageantry and planning for His Highness to settle.
