Well, sorta 30/second, but really it's more like 60 every-other-line 
scans/second, then add two half-scans together to get 30 complete 
frames per second.

However, that was the deal during the days of vacuum tubes -- maybe 
these days with CCDs and stuff like that they just do 30 entire 
frames/second. Got it?
