I wonder how they do the 'lines of scrimmage' graphic that comes up in football games... the line where the ball is and the line the ball has to cross so the team can get another 1st down. They fade in before the play, they move with the cameras, and when a player crosses over the line it's blocked but still 'visible' on the field. I wonder if there's sensors in the line markers on the sidelines that beam a signal across the field that the computers in the production truck pick up.
I know that in MLB the ads behind the batters are just green-screens and the ads are thrown in by computer.
I also wonder what else on 'live TV' is computer generated...
