CLEAN : WC2014: goal line technology to be used for the first time

The video tutorial discusses a digital system used in sports to determine if a goal has occurred. It covers the system's offline capabilities, development, and testing process, which took about five years and involved over 10,000 shots. The referee has the final decision, although the system provides reliable information. The system uses seven cameras per goal, capturing 500 pictures per second, and transmits data via fiber optics to a computer system.
