The Decision Review System(DRS) is a technology based system in cricket to assist the match officials with their decision making.

DRS – The history book stats!

The Umpires have been provided with UDRS since November 1992, and the formal DRS to add player’s Review was used in a Test match in 2008 (India vs Sri Lanka) , One Day International in January 2011 (England vs Australia) and in Twenty 20 Internationals in October 2017 (India vs New Zealand).

The system was first introduced in test cricket for the sole purpose of reviewing controversial decisions made by the on field Umpires to declare a batsman as OUT or NOT OUT. It was first tested in 2008 and was officially launched by International Cricket Council in November 2009.

DRS- The Rulebook stats!

In Test Cricket 2  Reviews per 80 overs for both teams are allowed after which both the reviews are renewed. In ODIs and T20Is One review per innings is allowed for both the teams. If the review is unsuccessful the teams lose the review and if the review is successful then the review remains as it is.

DRS – The Tech out here!

The technologies used in Decision Review System are Television Replays, The Ball Tracking technology used to track the path of the ball, Microphones , Snickometer, Infra Red imaging to detect temperature changes as the ball hits the pad or the bat. The Technologies Used In Decision Review System are:

  • TELEVISION REPLAYS : including Slow Motion which is mainly used to check whether the catch is cleanly taken or not.
  • HAWK EYEBall Tracking technology that plots the trajectory of a bowling delivery that has been interrupted by the batsmen/batswomen often by the pad and predict whether it would have hit the stumps or not. This technology is mainly used for Leg Before Wicket(LBW) decisions where the umpire can check whether the impact of the ball is in line to the stumps , whether the ball is hitting the stumps , and whether the ball is pitching outside the leg stump or not. These three conditions are mandatory for LBW decision which is reviewed using Hawk Eye Technology.  Click here to read more!
  • SNICKOMETERDirectional microphones to detect small sounds made as the ball passes the bat or the padIt is mainly used for caught behind and LBW decisions. If the snickometer shows spikes while passing the bat then it indicates that the ball has hit the bat which can be used for both caught behind and LBW decisions. Click here to read more!
  • HOTSPOT: Infra Red imaging system that shows where the ball has been in contact with the pad or the bat.It mainly shows the point of contact between the ball , bat and pad . It is mandatorily used to check whether the ball has hit the pad or the bat first in case of LBW and checks whether the ball has hit the bat or not in case of caught behind. It can be said as a substitute to snickometer. Click here to read more!

A fielding team may use the system to dispute “Not Out ” decision and the batting team may dispute the “Out” decision using the Decision Review System. The fielding team captain or the Batsman can challenge the decision by signalling “T” with the arms or with one arm and bat. Once the challenge is invoked , acknowledged and agreed , the Third Umpire reviews the play using suitable technology and may overturn the on-field decision or stay with the on-field decision.
