What is that yellow stripe on the field in football and how do they move it around? Like what is it made of?

Question

I know absolutely nothing about football but I was watching the Bears tonight and I noticed that a yellow stripe was on the field and it kept moving around during the game. I don't know if it's a light or what...the guys step on it and everything I can't figure out what it's made of.

Answer 1

its the first down marker.. it doesnt really appear on the field.. the yellow line is generated by computer projection


To create the line, three game cameras are equipped with encoders that record their precise focus, zoom, and angle. A spotter on the field marks the position of the first-down mark. Another computer contains a 3D model of the field and a palette of colors for the playing surface, the players and the referee. Yet another computer figures out which camera is on-air. Thirty times per second, this data is collected and sent to a central processor that changes the tiny squares that make up the line to yellow, but only if they match the palette of the playing surface.

Answer 2

The yellow lines are put down electronically by a very sophisticated computer system located in the trucks outside the stadium. It takes as much computer energy and work to do the yellow 1st down line as it does for any task the production company will encounter. Some production companies do NOT have the technical skill or the people to produce the yellow line. You will only see it on a few of the networks. More are coming up with it all the time because viewers insist on having it.

Answer 3

Is this a serious question?

If it is... here's an answer for you. The yellow line indicates the line in which a team must move the ball to receive a first down (another 4 plays to get ANOTHER first down). It is computer generated, and only can be seen on TV. It's amazing what technology can do these days!

Answer 4

When your team has the ball, you get four attempts to move forward at least 10 yards. If you move it 10 yards, you get four more attempts. The yellow line is a computer generated marker for the television viewers to keep track of how far the ball has been moved. The players on the field can't see that line.

Answer 5

Fear not, killer.
*The stripe* that catches your attention is merely a HIGH-TECHIE method used nowadays to enhance the TV public's perception of the football game.
This "line" is only a COMPUTER GENERATED image that is created by the technicians inside the production room (all T.V.-broadcasted games are produced in a room like this.) These technicians are kept updated each minute of the game by it's progress and referees who wear microphones.
Again, these lines are merely computer-generated images that appear only on the TV screen, so no "evidence" is left on the field.

Answer 6

that yellow line indicates the 'first down' marker on the field. it isn't actually on the field (the players can't see it). it's a tool that the tv broadcasters use to show those of us sitting in our lazy-boy chairs eating chips and dip where the offense has to get to get a first down. you'll sometimes see a blue line. that blue line indicates the line of scrimmage.

Answer 7

It is a digital special effect to show where the line of scrimmage is and where they have to get to for the first down

Answer 8

It's not actually on the field...it's done through the "magic" of TV.

Answer 9

computer projected image of where the first down marker should be.

Answer 10

Get the F***K out of here! You can't be serious
