Decision Review System (DRS)
| Aspect | Description |
|---|---|
| Purpose | The Decision Review System (DRS) is a technology-based system used in cricket to review on-field umpire decisions. Its primary purpose is to rectify potential errors and improve decision accuracy. Teams can challenge on-field decisions, and the third umpire uses technology, such as ball-tracking and UltraEdge, to review the decision and provide a conclusive outcome. The DRS aims to ensure fairness and enhance the integrity of the game. |
| Ball-Tracking | Ball-tracking is a crucial component of the DRS. It uses technology to predict the path of the ball after pitching and helps in assessing LBW decisions. The system tracks the ball’s trajectory and provides data on whether the ball would have hit the stumps or not. Ball-tracking assists in making accurate decisions on the leg before wicket appeals. |
| UltraEdge | UltraEdge, also known as Real-Time Snicko, is another essential aspect of the DRS. It utilizes sound sensors and microphones to detect any faint edges or contact between the ball and the bat. UltraEdge provides conclusive evidence on whether there was a bat involved in an LBW or caught-behind decision, assisting the third umpire in making accurate decisions. |
| Hawkeye | Hawkeye technology is used in the DRS to analyze the ball’s trajectory, especially for LBW reviews. It provides a visual representation of the ball’s path and indicates where it would have hit the stumps. Hawkeye aids the third umpire in making decisions on whether the ball was hitting the stumps or missing them, contributing to accurate LBW decisions. |
| Limited Reviews | Each team is allowed a limited number of reviews per inning in the DRS. If a team’s review is successful (the on-field decision is overturned), they retain the review, but if the review is unsuccessful, they lose it. This system encourages teams to use their reviews judiciously and only challenge decisions they genuinely believe to be incorrect. |
