How are the graphics for the national phone numbers triggered during #eurovision?

“Graphics in three, two, one, now!”
*lengthy 1 kHz tone*
“Graphics away in three, two, one. now!”

Using an 1 kHz tone on an digital audio track in an MPEG-TS instead of… anything else (e.g. a subtitle track?) seems a little bit odd?

@smrqdt Well, it's well-tested and synched (and probably well-tested to be synched), and extremely resilient to failures. If *anything* fails it can still be done manually with zero switch-over time, instead of, you know, bungling the largest live broadcast of the year.

@henryk The sync thing is probably true, and I fully understand the announcement thing (also a lot of small broadcasters are participating without complicated broadcasting systems). But I would have though this is a common problem and there would be some value in adding some more information (e.g. which kind of graphics is shown).
