(pak & newzealand). 
 In ODI ckt, was launched officially for 1st time in Jan,2011 during England's 
tour to Australia. 
 Initially ICC made it mandatory in all international matches, but later on its 
use was decided upon the approval of both teams. 
 To increase accuracy, amendments have also been made to it time to time.
No, of reviewing options 
 Either of the opponent teams can have max, of 2 unsuccessful options 
 In case, if both the reviews of a teams proves wrong, then they are left on 
the decision of on-field umpire. 
 I n test ckt, after 80 over's, the reviews resets. 
 Beside this if the on-field umpire is doubting about a decision, he might 
also call for review by itself. 
 Note that whenever a player has to call for review, he has to make “T” 
with has hands
Components & working 
 Composed of three parts. 
1. HAWK EYE / EAGLE EYE: 
2. HOTSPOT: 
3. REAL TIME SNICKOMETER: 
 HAWK EYE / EAGLE EYE: 
 A ball tracking technology that plots ball trajectory to check whether the 
ball is going to hit the stumps or not..! It is like to check for LBW outs. 
 Exp: let D=distance from strike end, 
 (if D>2.5m OR travels more than 40cm before it is faced,)…is always 
declared not out.
Trajectories:
2. Hotspot 
 An infrared imaging system that illumines the spot where the ball comes 
in contact with bat or pad 
 Shortly, it checks out for the narrow contacts of ball with bat or pad 
 Its accuracy is about 90-95% 
 New high resolution cameras have been in use for the sack of accuracy
3. REAL TIME SNICKMETER 
 A system having an installed microphone in stumps so that to collect the 
sound produced by minor contacts when the ball comes in contact with 
the bat, 
 Shortly, it checks out the result of caught by case and makes it clear 
whether the ball came in contact with the bat or not. 
 It is like drawing a graph of sound waves.
Advantages & Disadvantages 
 Purity has been brought into cricket. 
 Rights of each player has been reserved. 
 Interest of viewers have been enhanced in cricket. 
 Sports & technology is getting mixed. 
 It is like that cricket is losing its natural flavor because of technological 
interruption.
