Abstract
Technology has gone a long way in proving its mettle in sports. It has created a niche for itself in every major sport on the planet. Be it the outdoor sports like soccer, tennis or cricket or their indoor counterparts like snooker, badminton or basketball, technology is used in each one of them. The system works via six (sometimes seven) high- performance cameras, normally positioned on the underside of the stadium roof, which track the ball from different angles. The video from the six cameras is then triangulated and combined to create a three-dimensional representation of the trajectory of the ball. Hawk-Eye is not infallible and is accurate to within 5 millimeters (0.19 inch) but is generally trusted as an impartial second opinion in sports. Hot Spot uses two infra-red cameras positioned at either end of the ground. These cameras sense and measure heat from friction generated by a collision, such as ball on pad, ball on bat, ball on ground or ball on glove. Using a subtraction technique a series of black-and-white negative frames is generated
into a computer, precisely localizing the ball’s point of contact. Instant replay is a video reproduction of something that recently occurred which was both shot and broadcast live. The video, having already been shown live, is replayed in order
for viewers to see again and analyze what had just taken place.
Key words: Technology, Sports.
