History

Initially tested in test cricket (india vs. srilanka) in 2008.

In test ckt,ICC launched it officially for 1st time on 24 Nov, 2009 played b/w (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.

It is like that cricket is losing its natural flavor because of technological interruption.
