On the first day of the first Test match of the Border-Gavaskar Trophy (BGT) 2024 being played between India and Australia, the wicket of Indian batsman KL Rahul has once again raised questions on the DRS i.e. Decision Review System. Recently, in the test match played between India and New Zealand, questions were raised on the technology of DRS in the wicket of Rishabh Pant. Many veteran cricketers said that despite having such advanced technology, sometimes the umpire faces difficulty in taking the right decision. Come, let us know about the technology used in DRS…
DRS (Decision Review System)
DRS was first used in Test matches in 2008, ODI in 2011 and T20I in 2017. This system is used by any team to challenge the decision given by the on-field umpire. When the decision given by the umpire is challenged, the third umpire uses technology to check whether the decision given should be maintained or changed.
DRS technology
In DRS, TV umpires mainly use three types of technology – Hawk Eye, Real Time Snicko and Hot Spot.
Hawk Eye – It is also called the Virtual Eye of the TV Umpire. In this, using ball tracking technology, after the bowler throws the ball, it is seen through the trajectory whether the batsman has stopped the ball on the line of the wicket. This technology is used for the decision of LBW.
Real Time Snicko – It is also called ultraage. In this, using a microphone, it is detected whether the ball has touched the pad or the bat first. It creates audio spikes through voice in real time, which helps the umpire in taking the right decision.
Hot Spot – Infrared imaging technology is used in this, which tells where the ball has made contact with the bat or pad. Advanced camera system is installed for infrared imaging.
In DRS, through television replays it is seen whether the ball hits the bat or not or where the ball is pitched and whether it hits the wicket or not. In this, videos taken from high definition cameras from different angles are analyzed. Apart from this, ball tracking technology is used to know the direction of the ball. Not only this, the TV umpire checks whether the ball has touched the edge of the bat through the sound of the microphone installed on the stumps. Also, the mark of contact between the ball and the bat is checked through infrared imaging.
