WEBVTT 00:00:00.240 --> 00:00:06.080 so last I checked we're a tech Channel 00:00:03.240 --> 00:00:13.559 but for some reason there's been a long time ongoing argument in our comment 00:00:09.040 --> 00:00:16.160 section about whether it's football or 00:00:13.559 --> 00:00:21.039 soccer well whichever side of the argument you're on and our writer John 00:00:19.039 --> 00:00:25.119 would like to gently remind everyone that both are perfectly legitimate names 00:00:23.279 --> 00:00:30.480 for the sport something that should interest all fans of association 00:00:27.920 --> 00:00:37.399 football also correct by the way is the recent surge in popularity of goal line 00:00:34.640 --> 00:00:42.520 technology so for those less familiar with the sport you're probably wondering 00:00:40.000 --> 00:00:48.559 how hard is it to tell when the ball goes into the goal we need tech for 00:00:45.440 --> 00:00:51.960 this actually it's a pretty frequent 00:00:48.559 --> 00:00:54.640 occurrence where the ball seems to just 00:00:51.960 --> 00:01:01.600 barely cross the goal line if for example the goalkeeper tries to save it 00:00:57.719 --> 00:01:04.199 while he is basically on the line or if 00:01:01.600 --> 00:01:11.640 it hits off the crossbar and bounces downward as in the 1966 World Cup final 00:01:08.320 --> 00:01:14.360 and since the ball has to be completely 00:01:11.640 --> 00:01:20.119 across the line to count this decision can often come down to literal 00:01:17.240 --> 00:01:26.320 millimeters meaning that referees won't always be able to get it right on their 00:01:22.799 --> 00:01:28.880 own go line technology seeks to remove 00:01:26.320 --> 00:01:34.479 this uncertainty with systems that are more sophisticated ated than mere 00:01:31.400 --> 00:01:37.479 instant replay in fact the systems 00:01:34.479 --> 00:01:40.640 currently used for major European and 00:01:37.479 --> 00:01:41.920 international matches use not just one 00:01:40.640 --> 00:01:49.600 but 14 different cameras with seven pointed 00:01:46.119 --> 00:01:52.600 at each goal and the way it works is 00:01:49.600 --> 00:01:55.680 really cool every camera is connected to 00:01:52.600 --> 00:01:59.119 a computer which can compare both the 00:01:55.680 --> 00:02:02.280 ball and the pitch that's the field to a 00:01:59.119 --> 00:02:04.920 3D bottle allowing the system to 00:02:02.280 --> 00:02:10.080 triangulate the position of the ball at any given moment and even if multiple 00:02:08.319 --> 00:02:15.000 cameras have their view of the ball blocked by something like a big group of 00:02:12.440 --> 00:02:20.080 players scrambling in front of the goal the system can still work since only 00:02:17.640 --> 00:02:26.560 three of the seven cameras are needed at a time to determine where the ball is in 00:02:23.160 --> 00:02:29.080 3D space if the system recognizes that 00:02:26.560 --> 00:02:34.000 the ball has completely crossed the goal line it will will send a signal to a 00:02:31.440 --> 00:02:39.720 special wristwatch worn by the referee to indicate that a goal should be given 00:02:37.239 --> 00:02:46.720 because this system relies entirely on computer analysis it allows the referee 00:02:42.879 --> 00:02:49.120 to rule goal or no goal almost 00:02:46.720 --> 00:02:53.319 immediately instead of Performing the lengthy video reviews similar to what 00:02:51.480 --> 00:02:58.159 you'd see in sports like American football and ice hockey and because 00:02:56.680 --> 00:03:03.799 these cameras are extremely sophisticated I mean we're talking as 00:03:00.159 --> 00:03:07.879 high as 500 frames per second goal line 00:03:03.799 --> 00:03:10.959 technology can be accurate to under 4 mm 00:03:07.879 --> 00:03:14.480 to demonstrate check out how close this 00:03:10.959 --> 00:03:16.920 call was during a 2016 match between 00:03:14.480 --> 00:03:21.159 Bournemouth and liver poool and even though the powers that be were hesitant 00:03:18.840 --> 00:03:26.360 to introduce it after a number of high-profile referee blunders this kind 00:03:23.920 --> 00:03:32.799 of camera- based goal line technology is now being used in these Major Leagues 00:03:30.120 --> 00:03:37.879 non-domestic competitions like the UFA champions league and Copa America have 00:03:35.480 --> 00:03:43.400 also embraced the technology and it was also used at the World Cup for the first 00:03:40.480 --> 00:03:49.159 time in 2014 and will be again at next year's World Cup in Russia but there's 00:03:46.560 --> 00:03:54.200 also a competing method that doesn't rely on cameras involving magnetic 00:03:51.799 --> 00:03:59.480 sensors that are embedded into the goal frame or even underneath the grass and a 00:03:57.400 --> 00:04:04.799 circuit that gets inserted into the ball itself self this system can determine 00:04:02.360 --> 00:04:10.319 when the ball enters the goal by measuring changes in the magnetic field 00:04:08.120 --> 00:04:14.799 it's less expensive than the high-speed camera scheme used by the big money 00:04:12.360 --> 00:04:20.720 competitions so you may see it become more common at lower levels of the game 00:04:17.639 --> 00:04:22.759 over time but there are likely to be 00:04:20.720 --> 00:04:29.199 concerns among players at the highest here about any modification to the 00:04:26.040 --> 00:04:32.160 standard ball and although purists of 00:04:29.199 --> 00:04:38.440 the sport have opposed the integration of technology in general baseball is a 00:04:35.759 --> 00:04:44.400 prime example of this claiming that human error is part of the game the 00:04:41.680 --> 00:04:50.320 current Trend does seem to be toward ensuring that goal calls on the pitch 00:04:46.960 --> 00:04:53.199 are correct especially with influential 00:04:50.320 --> 00:04:59.720 Mega clubs like Barcelona calling for the technology to be introduced in Spain 00:04:56.400 --> 00:05:01.440 so are you a soccer/football fan with an 00:04:59.720 --> 00:05:05.840 opinion one way or the other on goal line technology or heck maybe you have a 00:05:04.080 --> 00:05:10.919 comment about another Sports use of similar technology let us know how you 00:05:08.560 --> 00:05:15.520 feel in the comments and also tell us if you'd like to see more Tekken sports 00:05:13.320 --> 00:05:18.680 videos in the future I mean maybe we could even come up with a techie 00:05:17.080 --> 00:05:23.000 solution to help the Canadian national team improve its game 00:05:20.440 --> 00:05:28.880 or I guess the other option is uh we could just stick to 00:05:25.600 --> 00:05:31.160 hockey tunnel bear VPN lets you tunnel 00:05:28.880 --> 00:05:36.360 to one of plenty different countries allowing you to browse the internet and 00:05:33.160
