Explainer: goal-line technology and the World Cup

Goal-line technology is being used at the 2014 World Cup. The first goal confirmed by the system was in the game between France and Honduras.

A German company, GoalControl GmbH, won the rights to supply the technology to FIFA in 2013. It was used for the first time in the 2013 Confederations Cup in Brazil.

Frank Lampard’s goal that wasn’t in 2010 – if only for goal-line technology.

The GoalControl system uses 14 high-speed cameras (seven for each goal). These cameras film at 500 frames per second. Images from the cameras are processed to a margin of error of five millimetres, and within one second the referee receives a signal as to whether a goal has been scored.

In the France vs Honduras game, the system gave two decisions. The first decision was that Karim Benzema’s shot that bounced off the post was not a goal. The second decision confirmed that all of the ball did cross the line when the goalkeeper Noel Valladares tried to save the rebound from the post.

The goal was recorded as an own goal rather than credited to Benzema.

Goal-line technology was used to decide whether Karim Benzema’s second goal crossed the line.
