What is VAR? The Video Assistant Referee explained

The team consists of major video officers and three assistants who can use all 33 broadcasting cameras in the stadium, 12 of them are slow motion.

They also have two additional cameras designed to monitor possible offside and a computer generated line projected to the arena. In the knockout phase, an ultra slow motion camera is placed behind each target.

The VAR team is not just to review the shots of the referee's instructions. They constantly check for "obvious and obvious" mistakes behind the scenes.

Communication between the referee and the executives watching the video image is bidirectional. If the VAR judges that the referee made a mistake, they can notify him at any time via headphones.

Video Assistant Referee (VAR) is a football assistant judge who will review the decisions made by the referee and use video and headphones for communication. In 2018, after the International Football Association Council (IFAB) conducted a series of major competitions, the VAR was written in the rules of the game. This process begins with the Video Operator Assistant Referee and the Assistant Video Assistant Referee (AVAR) watching the problematic game with the Video Operation Room (VOR) monitor set with the help of the playing operator. This may be triggered by the VAR to check whether the comment should be recommended to the referee, by the reviewing request. If no VAR is found during the check, you do not need to communicate with the referee. This is called "silent check". If the VAR judges that there is a possibility of a clear mistake, contact the referee.

Assistant Video Assistant Referee (AVAR) is a current or former referee who is responsible for assisting the VAR in the Video Operating Room. AVAR's responsibility includes monitoring real-time real-time behavior when the VAR is "checked" or "reviewed", recording the incident, and communicating the results of the review to the broadcaster. VAR was invented by the Refereeing 0 project in early 2010 under the direction of the Royal Netherlands Football Association (KNVB). This system was tested through simulation tests during the 2012-23 season's top National Football League, Eredivisie. In 2014, KNVB urged the International Football Association Council (IFAB) to amend its competition law to use this system in a wider trial. IFAB approved the trial and complete implementation approach at the 2016 meeting
