(maybe?) dumb question about the games

I feel the need to say before anything that I have not read any of the books fully, only watched the movies (and I'm pretty sure my question isn't mentioned in the movies..)

With that out of the way, I'd like to know if it's ever mentioned how the districts watch the games, and I don't mean if they have TVs or not, I mean if they only watch their own tributes, or they watch all the tributes (sort of like a compilation of all the cameras depending what was more interesting at the time)

Sorry for the crappy english! not my first language as you can probably tell, if anyone knows the answer I'd be very grateful! :)
