Well I use to work alot with virtual sets during the time and try all solutions on market (brainstorm orad wasp)
the most flexible and complete one comes from VIZRT.
is not true you need alot of scripting.
But now depends of what you have to do and what you want from a virtual set
If is a set for elections and you want to display data from a database maybe you will need some scripting,
but if you want just to have a great way to display informations like financial, breaking news, simulations, weather, Vizrt comes with alot of solutions for this .
In case lets say you need to display on screen weather or anything related with maps is good to consider vizrt has curious maps solution included.
maybe you can contact me and give me more details email@example.com and i can give you advices.
