Hawk-Eye is the revolutionary ball-tracking system which enables Channel 4 viewers to get the most information about how players are really performing against each other out in the middle.

We use six cameras strategically-placed around the ground to follow every ball in flight, tracking it accurately from the moment it leaves the bowler's hand.

The resulting 3D images are then processed, taking into account swing, variable bounce, trajectory and deviation to determine exactly what each player is doing, and also how each team uses specific tactics to get key opposition players out.
