Fifa is to review how it broadcasts
goalline technology decisions after the process caused confusion during a World
Cup game between France and Honduras.
GoalControl-4D - how it works
- 14 cameras, seven per goalmouth positioned
high around stadium
- All objects within camera range are tracked
- Ball's position is continuously and
automatically captured in three dimensions (X-, Y- and Z-coordinates) when
close to the goal
- Players and referee filtered out by
GoalControl computer system
- System shows the ball's position in 3D to
within a few millimetres
- If the ball crosses the goal line, the system
sends an encrypted radio signal to the referee's watch in less than one
second
- Virtual 3D image of incident from any camera
angle can be shown on screen
On Sunday in
France's 3-0 win, goalline technology was used for the first
time at a Fifa World Cup to aid a decision.
Replays
showed a 'no goal' graphic before judging the ball later crossed the line after
hitting the goalkeeper.
Honduras
coach Luis Suarez and his French counterpart Didier Deschamps were left
confused by the process.
"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," said a statement from football's governing body.
"In
order to ensure maximum clarity in the future for those unfamiliar with GLT,
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."
