What does this tiny little switch do? (P or N)

    I've just found this tiny, little switch on the back of my cam. It's on the side of the little board, and has two positions; One is labelled 'N' (what it was set to when I got it) and the other is labelled 'P'.

    Not sure what they do. Any ideas?

    (PS: Merry Christmas!)

    N = NTSC for USA video, P = PAL for Europe. (there are a few exceptions.)

    Thanks! Got some good info from Wikipedia (Source; Source2). So is this the selector for what type of broadcast signal I'm sending? Not too familiar with radio transmission. How would changing the switch affect the transmitter? Clearly I should just leave it on "N" and not touch it, but it would be good to know.
