1.Telestrator
From Wikipedia, the free encyclopedia
Jump to: navigation, search
In sports, the telestrator is typically used in conjunction with instant replay to diagram and analyze a recent play.The telestrator is a device that allows its operator to draw a freehand sketch over a motion picture image.
History
The telestrator was invented by physicist Leonard Reiffel, who used it to draw illustrations on a series of science shows he did for public television in the late 1960s. The user interface for early telestrators required the user to draw on a TV screen with a light pen, whereas modern implementations are commonly controlled with a touch screen or tablet PC.
Today telestrators are widely used in broadcasts of all major sports. They have also become a useful tool in televised weather reports.
2.Hawk-Eye is a computer system used in cricket, tennis and other sports to track the path of the ball. It was developed in 2001 by Dr. Paul Hawkins while working at Roke Manor Research Limited. Later, the technology was spun off into a separate company, Hawk-Eye Innovations Ltd., as a joint venture with television production company Sunset + Vine.
3.Skycam is the trademarked brandname of a patented, computer-controlled, stabilized, flying camera system. The system, similar to Steadicam, but maneuvered through three dimensions in the open space over a playing area of a stadium or arena by computer-controlled cable-drive system, is responsible for bringing video-game-like camera angles to television sports coverage. The camera package weighs less than 30 pounds and can travel at 30mph.
