World Cup 2014 Goal Line Tech Proves Itself During France v. Honduras: How Does it Work?
Sunday's World Cup match between France and Honduras marked a milestone in soccer history: it was the first time that technology helped determine a goal. Despite some confusion on the broadcasting end, the event helped prove that goal line technology could become a soccer staple in the future.
Here's a look at what makes the tech tick.
The system in use at the 2014 FIFA World Cup is the German-based GoalControl, which uses 14 cameras (seven on each goal) mounted on the stadium roof or catwalk to capture the ball in three dimensions in real time. There isn't too much fancy play after GoalControl determines whether or not the ball passed the goal line. Within one second of the ball passing the goal line, referees on the pitch receive a vibration that helps them in their "goal or no goal" decision.
Goal line technology has always been contested in the game of soccer, where players and fans alike clamour for uninterrupted play, but after the 2010 England Lampard debacle, FIFA has caved into the necessity of a fair game.
GoalControl passed its first test Sunday when France played Honduras and a shot from France's Karim Benzema was revealed to have crossed the goal line after Honduran goalkeeper Noel Valladares knocked the ball towards his own net. It took less than one minute to convey the decision to the audience, showing that goal line technology doesn't necessarily have to interrupt the flow of "The Beautiful Game" for long periods of time. Still, despite its success, FIFA is working to make sure there is less downtime and more accuracy in the future.
"What we are now doing is working to make it even more clear and we will modify guidelines on the key relevant goal line technology animations in cases such as yesterday so that you just see a goal sign," a spokeswoman for FIFA said on Monday.
One thing that did go wrong, however, was the fact that two conflicting replay angles confused television viewers, including announcers commenting on the match.
"The first replay that was used showed the ball hitting the inside of the post and not fully crossing the line, before the next replay aired seconds later with the animation confirming the ball had fully crossed the line after it had hit the goalkeeper," FIFA said in a statement.
"In order to ensure maximum clarity in the future for those unfamiliar with [goal line technology], FIFA will review the coverage of this match with the broadcast production team and GoalControl GmbH, to see if any improvements can be made to enhance the viewing experience for fans."
