IND vs AUS (DRS in Cricket)
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 once again raised questions about the DRS i.e. decision review system . Recently, in the Test match played between India and New Zealand, questions were raised about the DRS technology on Rishabh Pant’s wicket. Many senior cricketers said that despite having such advanced technology, sometimes the umpire faces difficulty in taking the right decision. Come tell us 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 taken by the on-field umpire. When the decision made by the referee is challenged, the third referee uses technology to check whether the decision made should be maintained or changed.
DRS technology
In DRS, television referees mainly use three types of technology: Hawk Eye, Real Time Snicko and Hot Spot.
hawk eye It is also called the TV Referee’s Virtual Eye. In this case, using ball tracking technology, after the bowler delivers the ball, it is seen through the trajectory whether the batsman has stopped the ball on the wicket line. This technology is used for the LBW decision.
Snicko in real time It is also called ultra-age. In this case, a microphone detects whether the ball has touched the pad or the bat first. Creates audio spikes through voice in real time, helping the referee make the right decision.
Hot Spot – This uses infrared imaging technology, which indicates where the ball has made contact with the bat or pad. An advanced camera system is installed for infrared imaging.
In DRS, through television replays you see whether the ball hits the bat or not or where the ball is bowled and whether it hits the wicket or not. This analyzes videos taken with high-definition cameras from different angles. 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 by sound from the microphone installed on the stumps. Additionally, the contact mark between the ball and the bat is verified using infrared images.
