Closed and open PCV system, what's the difference?

Hello agn!
Pretty simple there!
I read about open PCV system and closed one? What's the difference?

-A 1968 camaro sb with a tube from valve cover to air filter and another one from valve cover to carb (with pcv)would be open right?
-A 1967 camaro sb with only a tube from oil filler neck to carb would be closed?
Just want to confirm as a friend of mine is arguing that a closed PCV system is A.I.R setup, which was used for california models only I think.

Thanks a lot!
