Information technology in the Champions League
Football fans have waited 18 September kicked off the first round matches of the Champions League 2018/2019. The first game of the day brought a judicial error. Overview of Liverpool – PSG clearly shows that could not activate the goal of Tom Meunier from an offside and Edinson Cavani. In the match Galatasaray – Lokomotiv has not been assigned a controversial penalty for handball Ignatieff in the first half. In both situations, the judges could help system VAR, but it’s not used in Champions League matches. What new technologies are already being applied in football, and which are only on the threshold of introduction, you will learn in this article.
System VAR will not work in the Champions League 2018/2019
Despite the successful job Video Assistant referee (var football) world Cup matches in 2018, this tool will help the referees in this season’s Champions League. In fact, many arbitrators are confused about when to go to watch the replay, and when you can’t do it. Occurred and such funny situations, when the referee watched the replay, but took the wrong decision. The conclusion is that VAR is ready for deployment in the Champions League, but not ready referees.
Another stumbling block is the cost of the system VAR for football. Only the installation of all cameras, providing data and display information on the monitors is estimated at least $200 000. Even in the Champions League not all clubs are willing to pay that kind of money. Given the fact that 16 of 32 teams and the tournament will last a total of 6 matches, this technology may be unnecessary until next season.
VAR’ve already completed season in the national Championships of Italy, Portugal and Germany. In the championship of Russia 2018/2019 VAR will be used in the play-offs for relegation and some matches of the Cup of Russia.
How does VAR
The system is applied in four cases:
The removal of the player.
Determination of the severity of the violation, the player.
From the penalty spot.
In any of the contentious issues to the main referee can request a video assistant or the video assistant will give a signal about the violation. If the episode is ambiguous, the referee can review the moment on a screen located a few meters from the fields near the Central line.
Armed with VAR is 35 cameras in the stadium, including drones, fixing any controversial issue from different angles. For processing the entire video stream in a separate room is 10 monitors, the picture for which the following four judges and four operators.
Each judge is responsible only for their area of work:
Main video assistant monitors the stream from the main camera and examines in detail episodes on the other monitor.
While the video referee examines a moot point, the first officer continues to monitor the live broadcast.
The second assistant records the points associated with the offsides.
Third assistant chief in the assessment of controversial episodes.
Data from the cameras delivered live-assistant fibre-optic cables with a delay of 0.3 seconds. Referee and video-assistant to communicate through a radio link.
The system automatically determine the goals
Information technology in football can work without an arbitrator. Automatic determination of the goals was implemented in the Champions League back in season 2016/2017. With the advent of Goal-line technology no longer need the services of a judge, which was to monitor the goal line. The rules of football state that a goal is scored only if the ball completely crossed the goal line. Human reaction is just not able in dynamic scenes to determine the absolute goal. The solution was the development of British engineers Hawk-Eye.
System Hawk-Eye to football was used successfully in tennis and cricket. Based on seven high-speed cameras spread across the field, Hawk-Eye constantly calculates the location of the ball on the field using computer simulation. If the soccer ball was completely behind the goal line, the chief justice receives a signal on the clock accompanied by vibration. The error is 5 mm.
Another principle involved in the system called GoalRef. Danish-German development, uses electromagnetic induction, creating a magnetic field between the arms and the crossbar. For this purpose, a gate frame mounted sensor and the ball stretched the chip. When the chip crosses the magnetic field, the system will signal to the referee about the goal. GoalRef were approved by UEFA, but the difficulty in mounting of sensors and the complaints of players about the unpredictable flight trajectory of the balls with chips prevented the introduction of technology in football.
All major competitions, including the Champions League 2018/2019 use Hawk-Eye and similar systems. To install all of the cameras and maintenance of equipment you will need at least $300,000.
It is obvious that the next stage in the development of new technologies in football should be automatic detection of offside, but in 2018 a tool does not exist yet. There are some applications related to GPS, but they can not boast of reliability.
Live broadcasts of UEFA Champions League
The use of technology in football aims not only to aid referees. Fans should enjoy watching what VR technology being introduced in football.
To draw a straight VR-broadcast, you need multiple VR-cameras located in places with nice view. The image of one of the VR camera 180 degrees to form 12 conventional cameras. The result is a stereoscopic view. The more dots the location of the equipment, the more options for viewing in the viewer. The cameras can be located not only at the stadium – interesting for fans place is the view from the stands of the premises or next to the bench.
Next to the stadium are two trucks, which are transmission cables. In the first truck are the people who control the output video stream on VR helmets, and the second commentator. One of the advantages of such a broadcast is the ability to display statistics of the match directly in the incoming video stream is a good tool for live bets. Audio data can include crowd noise and the commentator’s voice.
In reality everything is not so smooth ? the picture quality is worse than on a regular TV, it constantly slows down and find VR football matches is almost impossible. A pity, because to watch the match real Madrid – Roma online much more interesting, feeling at the legendary Santiago Bernabeu stadium next to defender Sergio Ramos. The football community has already tested VR broadcast on the UEFA Champions League 2017/2018, some matches of the 2018 world Cup and a friendly game of Russian national team against Turkey.
Football and technology are increasingly interacting, which has led to a serious breakthrough in the collection and processing of football statistics, but this is a topic for another material.
