Is that the reason for this breakdown that went unnoticed for over a minute a few months back? Not able to override it immediately?
Unlikely to be anything to do with the announcers sound desk issue dbl mentions above as that won't affect the directors ability to cut the vision away from a fault. Looks like it was just someone not paying attention, I think it was late at night.
Also the new playout suites only came online this year, so that snooker was going through the old one.
Of course it could just be that the announcer was indisposed or that a backup suite was being used that doesn't have an announcer to hand
