Its presence was first in the 2018 World Cup provides a touch of technology capable of knowing right and wrong breach. Although sometimes the user must stop the match, but the blessing many wrong decisions made by referees. As a more advanced technology, VAR can be said to offer a lot of advantages for football. But like other manmade, he also still has a negative side. Video assistant referees assessed by many observers has changed the taste of football is often marred by a controversy and drama.

Before the present as it is now, VAR is a technology that has been developed a few years ago.VAR technology applied only this time in the tournament FIFA World Cup class. Before the system is tested in the European leagues and the world junior tournament. While the GLT has been tested at the 2014 World Cup. VAR and GLT presence inevitably makes the referee is now nearly perfect foresight. Thin vital possibility of error, fatal error or stupid carelessness that makes the referee so rundungan. For those cons, the presence of technology in football has rated making no more thrilling. One of the fun in football is controversy. That’s what makes people arguing and talking for days, weeks or years after the controversy occurred.As an ancillary equipment, VAR duty to minimize refereeing errors that do not always see clearly what happened by a referee. World Cup 2018 in Russia was the beginning of the device in action on the gridiron. Noted there are already more than 20 decisions made through this VAR tool. Starting from awarding a penalty to the determination of whether or not offside football players. In its work for the 2018 World Cup, the VAR can not alone, he was working with 13 members of the referees. Where there are four people in each match will be the operator of the tool. Do not stop there, for optimum results video assistant referees is also equipped with 33 cameras and 12 are capable of super who could capture all the events over the green field. Starting from a camera that has a normal speed until being able to see a potential for offiside. Because of these players who do not commendable in the match will be easily identified.

There are currently two popular GLT system used in football. First, the Hawk-Eye technology created a British artificial intelligence expert Dr. Paul Hawkins. Second, developed GoalRef German research institute, Fraunhofer IIS, in collaboration with FIFA. This system is used in cricket became popular since the early 2000s. While GoalRef start studied since early 2012. GoalRef system developed FIFA actually been born far away before. In simpler systems that have been found since the 1970s by a German company called Precitec. Osilatori circuits embedded in the ball will be the trigger that sends the voltage on the receiving line installed in the line and around the goalposts.

Simple circuit system has been registered with the United States Patent and Trademark Office since July 19, 1978. The FIFA Development conducted GoalRef refers to systems belonging to Precitec, the company has now disbanded it. The system is more complicated then found 1987 by Ronald James Brandon and Winger. Electronic methods combined with computer and radio transmitter is capable of tracking in the field area Which is ball. The system will sound when the ball leaves the area of ​​the field or into the net. This system was used soccer. In 1998, James D. Crawford enhance electronic detector goaland applying it to the sport of ice hockey. In contrast to football, predict whether the ball plate or not is very difficult goal in ice hockey. Sensors of this Crawford started to be used in competition NHL a few years later. Since then at each wicket installedstrobolightand sirens which will both be lit when the puck enter the goal line. GLT growing development in the decade of the 2000s. In the event the user needs GLT domestic competition is increasingly urgent because many incidents occur phantom goals. GLT present is to minimize their goals this ghost. ghost goal is a term popularized by Jose Mourinho in 2005. At that time he was disappointed with the goals Liverpool striker, Luis Garcia, who believes is unlawful and has not entered into the Chelsea goal in the Champions League semi-final match of 2005. In Germany, the term is called a ghost goal Phantomtor.

In the event the World Cup tournament 70s, 80s, 90s and early 2000s when the actually existing GLT technology, the emergence of a controversial phantom goal never happened. At the moment it finally happened June 27, 2010 when England face Germany in the last 16 of the World Cup. In the 38th minute, Frank Lampard shooting the ball and the ball on the bottom of the crossbar and then bounced into the goal. But the referee did not see this as a goal. In fact, from the record, Lampard’s shot was supposed to be a goal. If the goal is authorized UK will equalize 2-2. Lampard scored annulment is claimed to make the UK become depressed and eventually slaughtered 4-1 by Germany. German public refer to it as “revenge for Wembley goal”. This proverb refers to the time they bent England in the 1966 World Cup final.
When the 1966 World Cup, GTL technology has yet emerged. However VAR can actually be used as a solution to annul the English goal.

In contrast to the GTL, technology VAR born of simple things actually been available since time immemorial. Video analyzed fourth man in the room VAR derived from broadcasting the match. Direct television broadcasting began in the 1954 World Cup in Sweden. The problem at the 1954 World Cup, in 1958 and 1962, the technology of instant replay has not been found. Withoutinstant replay, Hard look at the replays that occurred during the match. Those watching at home will enjoy the same experience as that experienced by spectators in the stadium. In the era of recording reruns is not new. Since 1955 CBC television often do so in the hockey event using kinescope or Ampex Quadruplex system. Only this recording so not instant because it can be broadcasted to pause long enough for many minutes. The system is also unable to show slow motion, freeze-frame, and fast forward or rewind a flexible time index points. CBS Sports Director Tony Verna the first time finding systeminstant replaythis. He created a system that allows a standard video cassette machine played back directly. This machine weighs 590 kg and tested the first time on December 7, 1963.

With this system, the use of multiple cameras in one event began prevalent. When one camera recording the scene inwide, Then the camera will again be watching the action “live” in the star fieldclose-upfrom different angles and in slow motion. And Verna machine work combines it all inlive, impressionsinstant replayThis began to be used in the 1966 World Cup who was then the BBC stations broadcast the final match, featuring re-recorded when the wicket keeper Hurst West Germany, Hans Tilkowski. There are three cameras were used: from the top of the stands, on the edge of the field and from behind the goal. From this record does not appear that the ball crossed the goal line. When the process of the goals came, the Swiss referee Gottfried Dienst, unsure whether it was a goal or not. He ran over and consulting his linesman, Tofiq Bahramov Soviet origin.
