The Board of Control for Cricket in India (BCCI) finally bit the Decision Review System bullet and implement it in the upcoming five-Test series against England on a trial basis. The board said the move would not be permanent until it can "evaluate the improvements made" in the system.

This is the first time India will be using the DRS since 2008 in a Test match. The Indian cricket board's main bone of contention with the DRS was that the Hawk-Eye technology used to review leg-before-wicket decisions was not foolproof.

The DRS can be used if one of the team’s wants an umpire’s decision to be rechecked. There are aspects of the DRS that one has to understand. The Improved Ball Tracking Technology, which shows the zone of the impact when the ball hits the pads.

The Ultra Edge, which is a ball tracking system designed by MIT based on ultra-motion cameras to determin the position of the ball. It is more accurate that the snick-o-meter which shows if the ball has edged the bat or not. An improved hotspot also works for the bowlers. It is more of a bowler’s aide that a batsmen’s.
