1
00:00:00,240 --> 00:00:06,080
so last I checked we're a tech Channel

2
00:00:03,240 --> 00:00:13,559
but for some reason there's been a long time ongoing argument in our comment

3
00:00:09,040 --> 00:00:16,160
section about whether it's football or

4
00:00:13,559 --> 00:00:21,039
soccer well whichever side of the argument you're on and our writer John

5
00:00:19,039 --> 00:00:25,119
would like to gently remind everyone that both are perfectly legitimate names

6
00:00:23,279 --> 00:00:30,480
for the sport something that should interest all fans of association

7
00:00:27,920 --> 00:00:37,399
football also correct by the way is the recent surge in popularity of goal line

8
00:00:34,640 --> 00:00:42,520
technology so for those less familiar with the sport you're probably wondering

9
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

10
00:00:45,440 --> 00:00:51,960
this actually it's a pretty frequent

11
00:00:48,559 --> 00:00:54,640
occurrence where the ball seems to just

12
00:00:51,960 --> 00:01:01,600
barely cross the goal line if for example the goalkeeper tries to save it

13
00:00:57,719 --> 00:01:04,199
while he is basically on the line or if

14
00:01:01,600 --> 00:01:11,640
it hits off the crossbar and bounces downward as in the 1966 World Cup final

15
00:01:08,320 --> 00:01:14,360
and since the ball has to be completely

16
00:01:11,640 --> 00:01:20,119
across the line to count this decision can often come down to literal

17
00:01:17,240 --> 00:01:26,320
millimeters meaning that referees won't always be able to get it right on their

18
00:01:22,799 --> 00:01:28,880
own go line technology seeks to remove

19
00:01:26,320 --> 00:01:34,479
this uncertainty with systems that are more sophisticated ated than mere

20
00:01:31,400 --> 00:01:37,479
instant replay in fact the systems

21
00:01:34,479 --> 00:01:40,640
currently used for major European and

22
00:01:37,479 --> 00:01:41,920
international matches use not just one

23
00:01:40,640 --> 00:01:49,600
but 14 different cameras with seven pointed

24
00:01:46,119 --> 00:01:52,600
at each goal and the way it works is

25
00:01:49,600 --> 00:01:55,680
really cool every camera is connected to

26
00:01:52,600 --> 00:01:59,119
a computer which can compare both the

27
00:01:55,680 --> 00:02:02,280
ball and the pitch that's the field to a

28
00:01:59,119 --> 00:02:04,920
3D bottle allowing the system to

29
00:02:02,280 --> 00:02:10,080
triangulate the position of the ball at any given moment and even if multiple

30
00:02:08,319 --> 00:02:15,000
cameras have their view of the ball blocked by something like a big group of

31
00:02:12,440 --> 00:02:20,080
players scrambling in front of the goal the system can still work since only

32
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

33
00:02:23,160 --> 00:02:29,080
3D space if the system recognizes that

34
00:02:26,560 --> 00:02:34,000
the ball has completely crossed the goal line it will will send a signal to a

35
00:02:31,440 --> 00:02:39,720
special wristwatch worn by the referee to indicate that a goal should be given

36
00:02:37,239 --> 00:02:46,720
because this system relies entirely on computer analysis it allows the referee

37
00:02:42,879 --> 00:02:49,120
to rule goal or no goal almost

38
00:02:46,720 --> 00:02:53,319
immediately instead of Performing the lengthy video reviews similar to what

39
00:02:51,480 --> 00:02:58,159
you'd see in sports like American football and ice hockey and because

40
00:02:56,680 --> 00:03:03,799
these cameras are extremely sophisticated I mean we're talking as

41
00:03:00,159 --> 00:03:07,879
high as 500 frames per second goal line

42
00:03:03,799 --> 00:03:10,959
technology can be accurate to under 4 mm

43
00:03:07,879 --> 00:03:14,480
to demonstrate check out how close this

44
00:03:10,959 --> 00:03:16,920
call was during a 2016 match between

45
00:03:14,480 --> 00:03:21,159
Bournemouth and liver poool and even though the powers that be were hesitant

46
00:03:18,840 --> 00:03:26,360
to introduce it after a number of high-profile referee blunders this kind

47
00:03:23,920 --> 00:03:32,799
of camera- based goal line technology is now being used in these Major Leagues

48
00:03:30,120 --> 00:03:37,879
non-domestic competitions like the UFA champions league and Copa America have

49
00:03:35,480 --> 00:03:43,400
also embraced the technology and it was also used at the World Cup for the first

50
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

51
00:03:46,560 --> 00:03:54,200
also a competing method that doesn't rely on cameras involving magnetic

52
00:03:51,799 --> 00:03:59,480
sensors that are embedded into the goal frame or even underneath the grass and a

53
00:03:57,400 --> 00:04:04,799
circuit that gets inserted into the ball itself self this system can determine

54
00:04:02,360 --> 00:04:10,319
when the ball enters the goal by measuring changes in the magnetic field

55
00:04:08,120 --> 00:04:14,799
it's less expensive than the high-speed camera scheme used by the big money

56
00:04:12,360 --> 00:04:20,720
competitions so you may see it become more common at lower levels of the game

57
00:04:17,639 --> 00:04:22,759
over time but there are likely to be

58
00:04:20,720 --> 00:04:29,199
concerns among players at the highest here about any modification to the

59
00:04:26,040 --> 00:04:32,160
standard ball and although purists of

60
00:04:29,199 --> 00:04:38,440
the sport have opposed the integration of technology in general baseball is a

61
00:04:35,759 --> 00:04:44,400
prime example of this claiming that human error is part of the game the

62
00:04:41,680 --> 00:04:50,320
current Trend does seem to be toward ensuring that goal calls on the pitch

63
00:04:46,960 --> 00:04:53,199
are correct especially with influential

64
00:04:50,320 --> 00:04:59,720
Mega clubs like Barcelona calling for the technology to be introduced in Spain

65
00:04:56,400 --> 00:05:01,440
so are you a soccer/football fan with an

66
00:04:59,720 --> 00:05:05,840
opinion one way or the other on goal line technology or heck maybe you have a

67
00:05:04,080 --> 00:05:10,919
comment about another Sports use of similar technology let us know how you

68
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

69
00:05:13,320 --> 00:05:18,680
videos in the future I mean maybe we could even come up with a techie

70
00:05:17,080 --> 00:05:23,000
solution to help the Canadian national team improve its game

71
00:05:20,440 --> 00:05:28,880
or I guess the other option is uh we could just stick to

72
00:05:25,600 --> 00:05:31,160
hockey tunnel bear VPN lets you tunnel

73
00:05:28,880 --> 00:05:36,360
to one of plenty different countries allowing you to browse the internet and

74
00:05:33,160 --> 00:05:38,759
use online services like video streaming

75
00:05:36,360 --> 00:05:43,520
services as though you are in a different country it is a great way to

76
00:05:41,360 --> 00:05:49,560
get access to content that's behind pesky Geo restrictions they have easy to

77
00:05:47,199 --> 00:05:55,720
use apps for iOS iOS Android PC and Mac they also

78
00:05:52,840 --> 00:06:01,360
have a Chrome extension and it is so simple to use that there is just no

79
00:05:58,639 --> 00:06:07,720
excuse for for not encrypting your connection and hiding from advertisers

80
00:06:05,000 --> 00:06:12,599
and your ISP or anyone who wants to spy on what you're doing online your

81
00:06:10,080 --> 00:06:18,080
activities you just press pretty much one button and boom you are anonymized

82
00:06:16,440 --> 00:06:23,000
