The studio production is 59.94i
Since the move to HD, it's been a LOT easier to make shows in different frame-rates in Europe - as the image format remains the same (1920x1080 or 1280x720 - though the latter is rare outside North America - as in Europe 720p broadcasters usually run 1080i in studios and OBs)
As a result the same cameras, switchers, VTRs, CGs etc. all can now usually easily switch.
Yes, and last year most (all ?) of the European (and therefore '50Hz' based) trucks that were in Rio for the Olympics host broadcaster (and unilateral) coverage, were running at 59.94.
At least one OB company did take 60 Hz to 50 Hz mains inverters. Brazil's electrical supply is 220/380 volts but of course 60Hz, electronic kit with SMPSUs has no issues with that difference of frequency, but air con compressors and similar do (or can do)
Yes - the real challenges are when you shoot 'off frequency' - i.e. shooting 50Hz video in a 59.94Hz country or vice versa. The big issue is usually lighting flicker. If you film in areas in which you can't control the lighting, and the lighting is mains-frequency discharge, you get horrible flicker. You can sometimes shutter this out - but if you are shooting with non-globally shuttered cameras, or with motion that isn't conducive to shuttering, it looks horrible.
Pity poor Japan - they have both 50Hz and 60Hz mains to contend with - the country is split in half...
