1x Scoreboard Court One 1080i50
1x tournament statistic
1x Lgraphic (1080i) feeding 150 TV sreens in the venue
quite a list but more impressive which actually makes casparcg the real tool of choice is the way it can be controlled
server 1,2 & 3 are all controlled by one person during players introduction. 3 servers sync-rolling several channels !!
during showblocks parts off the playout were controlled by the LD (lighting director) with OSC but some other layers still by the VT at the same time
during the game the same servers are controlled by several persons in different ways.
1 the umpire with scoreboard data
2 hawkeye personal switching to the hawkeye feed and triggers all LED screen channels
3 showing hawkeye stats during sitdowns
4 Set and Match points animations controlled by the showcaller
while server 4 is all controlled by external data
of coarse non open-source software can do this too (probally even better) but NOT in the same budget!!
did i mention that 6 semi trailers fully packed with displays / LEDsreens are just controlled by 4 CCG servers !!!
with EASE !!
big shout-out to all @Superfly and julian !!
some channels ran on cherrypicked NRKO 2.1 builds 
all others on 2.2 !
