1. Instant replay

is the replaying of video footage of an event or incident very soon . instant replay is often used during live broadcast, to show a passage of play which was important or remarkable, or which was unclear on first sight.

In NBA basketball, the officials must watch an instant replay of a buzzer beater to determine if the shot was released before time expired. Since 2002, the NBA also has mandated installation of light strips on both the backboard and the scorer's table that illuminate when time expires, in order to assist with any potential review.
"The referee may use technical equipment to determine on a last shot made at the end of each period or extra period, whether the ball has or has not left the player's hand(s) within the playing time."
In field hockey, the International Hockey Federation allows the match umpire to request the opinion of a video umpire as to whether or not a goal has been validly scored, and whether there was a violation in the build-up to a goal.
In Motor Sports, video replays are used to review rules infractions and scoring disputes.
video replay is used to determine if a car has crossed the pit entrance before the pit was closed for a yellow flag, used to supplement electronic scoring to determine the positions in which cars exit the pits (during cautions), also determines if drivers are following pit road speed limits.

2. Soccer Goal Line Technology

There has been a need for goal line technology in soccer, particularly as TV replays are showing in retrospect wrong decisions by the referee.

Possible Options:

Smart Ball

A promising prospect has been a "smartball" loaded with an computer chip, jointly developed by German companies Cairos Technologies and the Fraunhofer Institute for Integrated Circuits, an engineering research and software development company, along with the Adidas athletic clothing and shoe company. 
The companies' technology uses a network of receivers around the field designed to track the ball's precise position in real time - including exactly when it has fully passed the goal line. That information would be relayed in less than a second to a watch-like device worn by the referee.


The Hawke Eye system uses three cameras focused on each goal-line, and each taking footage at 600 frames a second. Hawk-Eye is able to give a definitive decision on whether the ball has fully crossed the line, and relay this information in the form of an audible beep to the central referee within half a second. 
As the Premier League referees use headsets, the signal is easily sent to them. In other leagues, other methods such as through a watch can be used.
