"Black Technology" in the 2018 World Cup

Official ball

This is the official ball of the Russian World Cup - "Telestar 18".

It is made of Brazilian environmentally friendly material, sugar cane extract. The color scheme is classic black and white. The dark part is also integrated with the mosaic pattern design, which is called the mosaic ball by netizens.

More importantly, the NFC chip is embedded inside. As long as the fans are close to the football, they can open the experience content, including the football product information and some online challenges, and even the ball's trajectory and the players' shooting skills can be viewed through NFC.

VAR technology

VAR is the abbreviation of Video Assistant Referee, which is the video assistant referee.

The VAR team consists of a Video Assistant Referee (VAR) and three auxiliary video assistant referees (AVAR1, AVAR2 and AVAR3). All members of the VAR team are top officials in the FIFA event.

In the event of a disputed offside goal, penalty penalty, red card, etc., the VAR team will give a hint to the on-site referee with the aid of the video to ensure the authority of the game.

Door line technology

Goal-line technology is a football aid that has emerged in recent years. It can judge whether the ball has entered the goal line with the help of the Hawkeye system to determine whether the goal is valid.

The Hawkeye system can track the path of the recording ball and display the graphic image of the actual path by means of multiple high-speed cameras. After analyzing the data, the result is transmitted to the special watch worn by the referee. If it is determined that the ball passes the door line, the watch "goal" will appear on the top, and the whole process takes less than a second.

Positioning spray

Presumably, many people noticed the magical spray in the referee's hand, used to mark the position of the free kick and the defensive wall, colorless and tasteless, flat fashion in the referee's waist. His magic is that the sprayed foam dissipates within 1 minute, leaving no traces and will not interfere with the game. Is it amazing?

The main component of the positioning spray is water, and there are some mixtures of butane. When the spray is sprayed, there will be small water droplets. The foam will only last for up to three minutes, and the water and activator remaining on the grass will be evaporated, and the grass and air will be left. No pollution, very environmentally friendly.

In the viewing experience, all 64 games of this year were broadcast live with 4K Ultra HD technology, and the BBC launched the VR program to make the audience feel more immersive...

With the help of a series of innovative technologies, this World Cup will undoubtedly provide a wonderful visual feast for fans around the world.

The World Cup is innovating and upgrading with the times.
