Intro:

Final preparations are taking place at the venues for the Confederations Cup - where Goal-Line Technology (GLT) will be used.

Script:

After much debate Goal-Line Technology will be implemented for the upcoming Confederations Cup in Brazil.

Final testing at the venues with the 'GoalControl' system is taking place as part of the official certification process.

The technology is due to eliminate errors such as goals wrongly given - or not awarded at all - if the ball has or has not crossed the line.

Goal-Control chairman Bjorn Lindner explained how the system works.

SOUNDBITE: (English), Bjorn Lindner, Goal-Control chairman:
"The whole system uses 14 cameras that are installed on the catwalk. We have seven cameras per goal and computers are connected to those cameras. The computers are catching the images - around 500 pictures per second - and we get by triangulation the position of the ball in real time, and once the computer precepts the ball has crossed the goal line it gives a signal to the referees watch. So all the referees on the field will see the signal, it vibrates and gives an optical signal 'goal' and he knows a goal has occurred."

The technology was also on hand at the FIFA Club World Cup in Japan last year - although it wasn't required.
