My girlfriend asked me this question yesterday and I wasn't sure how to answer it. When watching NFL on TV, how do they show the line of scrimmage on the field so that the players do not interfere with it. I know it's a computer program, but how do they layer it so it doesn't cut through the players when they cross it? Make sense?

It is probably put into the background somehow. The layer the program so players are on top of the imaginary line but the grass is below the imaginary line.

"There are eight computers... three sets of special encoders and abundant wiring dedicated to generating the virtual first down line in video format." The virtual line is drawn on video based on the position first down marker, ridiculously exact details of of the live camera's position (including altitude and lens angle), a digital 3D model of the field, and two palettes of colors for the field and the players. The player's colors automatically override the virtual line's colors, so it appears as though they're stepping over it."
