I’m referring to the yellow line FOX-TV uses in the broadcast of their NFL games. It’s obviously electronically imposed but I can’t figure out exactly how they do it. For one thing I’ve noticed that it seems to be used in such a way so that the players can be seen stepping over it, instead of having the line “keyed” over the entire picture. Are there any TV engineering types out there who can give a clue?
