Looking back at the schedule that has passed, the emergence of various "black technologies" is even more eye-catching than the "collective Mercury retrograde" of traditional strong teams that have broken many fans.

VAR referee team includes a main video assistant referee and 3 additional video assistant referees. They will intervene in the referee's imprecise judgment to avoid misjudgment.

can actively prompt the referee when there are four situations: goals, penalty kicks, red card penalty and mistaken player.

VAR is not only the referees who are staring at the screen in the "little dark room", but also refers to the entire set of video equipment and technology that supports them. In order to accurately and clearly record every action, VAR equipment not only includes 33 broadcast-level ultra-definition high-speed cameras, but also a series of matching tablets, headsets, video software, etc.

has changed the fate of many teams in the group stage and the eighth finals. In the first round of the group match between France and Australia, after VAR confirmation, Griezmann scored France's first penalty kick in this World Cup. During the group stage, VAR intervened and ordered 26 penalties. includes both the penalty kick that helped Iran 10 equalize Portugal, South Korea's first goal in stoppage time to defeat Germany, and the penalty kick that Neymar and Mane were cancelled after review.

It is true that although VAR performs well, it also brings a lot of controversy. Many fans called it, thanks to VAR, there have been more penalty kicks in this World Cup, the injury time has been extended, and the game rhythm has changed. In this regard, FIFA's judgment on the merits and demerits of VAR is: minimum intervention, maximum benefit (minimum intervention, maximum benefit).

Netizen comments on VAR

After so many games, Sikejun feels that VAR really makes the game more fair and transparent, and even the right referee is difficult to achieve "zero mistakes", so it is still necessary to bring high technology into the green field.

Why do the referee frequently look at the watch? Is he anxious to end the game ?

In this World Cup, every time the player scores a goal, the referee will look at the watch in his hand. At first, Sikejun, a "pseudo-fan", was puzzled why the referee was so anxious to look at the time. I later learned that this was the referee confirming the goal. How to implement such a magical operation in

? This has to mention a black technology - door technology . Goal-line technology is a football assistive technology developed in recent years. It can determine whether the ball has crossed the goal line and thus determine whether the goal is effective. The three systems of

Goal Control system, Hawkeye system and CG system support powerful goal line technology. The three systems use aerial photography, ultra-high-speed camera and magnetic field sensing to calculate and judge whether the ball crosses the goal line, and send the result to the referee's watch.

, like VAR, the "black technology" of gate line technology is also for the referee to improve the efficiency of punishment and reduce the factors of human intervention. Sikejun still said that the purpose of technical support is to make the competition fairer. Learn about

"TV Star 18" body is an upgraded version, equipped with a lot of intelligent "black technologies", such as NFC technology. It can connect mobile phones, referee watches and other devices to record and transmit ball speed, ball direction and other data. Each game ball has an exclusive "ID card". After unlocking the exclusive data information, you can view the ball's movement trajectory and the players' shooting skills. After

is equipped with this technology, the referee team's control over the information on the court will also improve. The receiver network is added to the stadium, and the backend system can track the precise position of the "smart ball" in real time, including when the player completely crosses the goal line on the field, and other data such as data. These key information will be passed to the bracelet and watch worn by the referee within one second, and the referee's probability of misjudgment will be greatly reduced.

can't come to the scene? Ultra-high definition immersive watch the game

Sikejun thinks that being a fan is definitely a technical job. Who says high technology is only exclusive to professional arenas? As the audience members who are watching football, can’t we live a more technological sense?

of course.

VR is one of them. This year, the BBC launched the World Cup VR preview service. As long as you equip VR equipment, you can "in person" to watch the game. Whether the video angle is switched to highlight or at low light at night, the video details in VR will not be lost, ensuring the integrity of the event details.

Sikejun's VR device is still on the way... So it's already very satisfying to watch 4K ultra-high-definition live broadcasts. With 4K quality resolution, the audience can see every detail and close-up in the picture clearly. For example, what is written on the yellow or red card in the referee's hand, or even the time on the referee's watch. Many friends should have enjoyed it this time, right?

The four-year World Cup is not only a feast for the sports world, but also a driving force for the development of the technology world. No matter what new technology is used, the ultimate goal is to let all those participating in this competition feel the unique charm of competitive sports.
