GLT (Goal-Line Technology) was used for the first time in the match between France and Honduras at the 2014 FIFA World Cup (final score 3-0). As TV images were not conclusive enough in showing whether or not France’s second goal was actually a goal, GLT animation offered the necessary support to show that it was a goal.
A GLT animation is used by Match Directors in broadcast production team. For FIFA World Cup 2014 the GLT provider is GoalControl GmBH. Such an animation appears when a ball crosses the line completely or when it is 30 cm inside the goal line.
The second goal scored by France highlighted a specific situation in which the ball first hit the inside of the post. It the rebounded away from the goal, hit the goalkeeper and rolled back across goal line.
During the first replay viewers saw that the ball did not fully cross the line. The following replay, which was shown instantly after, showed that the ball fully crossed the goal line.
