1
00:00:00,120 --> 00:00:06,440
these days we become used to instant gratification whether it's ordering at a

2
00:00:04,400 --> 00:00:11,160
drive-thru looking up incredibly important information on the connected

3
00:00:08,599 --> 00:00:18,080
computer in your pocket or gaming with someone on the other side of the planet

4
00:00:14,360 --> 00:00:20,080
we expect lots of things to happen

5
00:00:18,080 --> 00:00:26,720
instantaneously but as much as our technology has advanced we're still

6
00:00:22,800 --> 00:00:28,960
fighting the dreaded problem of latency

7
00:00:26,720 --> 00:00:34,920
and no I'm not talking about your repressed Freud and desires what I mean

8
00:00:32,000 --> 00:00:39,920
by latency is the gap in time between some kind of input like a key press or

9
00:00:37,480 --> 00:00:44,719
turning your head in a VR headset and the system spitting out the appropriate

10
00:00:42,160 --> 00:00:51,160
response and this latency affects the way that you use tons of things in the

11
00:00:47,800 --> 00:00:54,359
real world but why don't electricity and

12
00:00:51,160 --> 00:00:56,960
radio waves travel super fast well yes

13
00:00:54,359 --> 00:01:01,160
they do in fact radio waves travel at the speed of light while electricity

14
00:00:59,039 --> 00:01:06,080
traveling through wire can go up to nearly the speed of light but the issue

15
00:01:03,879 --> 00:01:12,960
isn't with how quickly a signal goes from A to B instead latency is caused by

16
00:01:09,840 --> 00:01:16,200
processing times and since any kind of

17
00:01:12,960 --> 00:01:19,280
input to a computer has to be processed

18
00:01:16,200 --> 00:01:22,479
everything has at least some amount of

19
00:01:19,280 --> 00:01:24,960
latency this can be very noticeable in

20
00:01:22,479 --> 00:01:29,240
situations where a slow hard drive causes doing something simple like

21
00:01:26,720 --> 00:01:35,240
finding a picture on your computer to be agon singly slow or when a web page is

22
00:01:32,880 --> 00:01:40,479
designed poorly and you can't click on anything for a few seconds while it

23
00:01:37,320 --> 00:01:44,320
finishes rendering you've also probably

24
00:01:40,479 --> 00:01:44,320
noticed latency if

25
00:01:44,960 --> 00:01:51,079
uh well if you've ever watched an interview via satellite on a news

26
00:01:49,000 --> 00:01:56,680
channel where the subject takes a few seconds to start responding to the

27
00:01:53,439 --> 00:01:59,119
reporters questions often these kinds of

28
00:01:56,680 --> 00:02:04,880
latency won't completely screw up what you're trying to do I mean waiting an

29
00:02:01,960 --> 00:02:11,319
extra 15 seconds to look at that TPS report probably won't ruin your day but

30
00:02:08,319 --> 00:02:13,599
latency can be an absolute killer in

31
00:02:11,319 --> 00:02:18,440
other situations if you enjoy playing games online high Network latencies

32
00:02:16,239 --> 00:02:24,519
caused by processing at each point in the network can cause weird laggy

33
00:02:22,000 --> 00:02:29,959
behavior that can result in catastrophic in-game mishaps or even getting kicked

34
00:02:26,879 --> 00:02:32,239
off The Game Server completely you can

35
00:02:29,959 --> 00:02:37,239
learn more about latency in games up here and believe it or not the

36
00:02:34,480 --> 00:02:42,440
consequence of high latency can be even worse than getting fragged in csgo with

37
00:02:40,599 --> 00:02:48,280
car manufacturers increasingly installing backup cameras and some cars

38
00:02:45,480 --> 00:02:54,680
even completely ditching mirrors in favor of cameras such as this BMW I8 we

39
00:02:52,879 --> 00:02:59,840
were checking out last year and I'm wearing a lavalier microphone on me that

40
00:02:56,879 --> 00:03:02,599
will give you guys an exact idea of how how much delay there is between

41
00:03:01,519 --> 00:03:08,879
something happening and what's on the screen low

42
00:03:05,879 --> 00:03:11,519
latency is a must so that drivers can

43
00:03:08,879 --> 00:03:16,319
react to hazards in time even half a second delay could lead to a tragic

44
00:03:14,239 --> 00:03:21,680
accident so how do you cut down on latency other than just having a faster

45
00:03:18,760 --> 00:03:26,799
computer well in Computing context a common tactic is to use wires where

46
00:03:24,200 --> 00:03:32,239
possible instead of going Wireless a good example of this is how current VR

47
00:03:28,720 --> 00:03:35,640
headsets like the Rift and the HTC Vive

48
00:03:32,239 --> 00:03:38,280
rely on wired connections to a PC

49
00:03:35,640 --> 00:03:43,120
although these wires are cumbersome wireless tech typically has greater

50
00:03:40,640 --> 00:03:49,319
latency due to more complicated processing which could mean disorienting

51
00:03:46,519 --> 00:03:55,000
or nauseating display lag when you're in a virtual world this is sometimes called

52
00:03:52,239 --> 00:03:59,799
motion to Photon latency and if you're gaming online and you have a choice of

53
00:03:57,040 --> 00:04:05,159
servers pick the one geographically closest to you although electrical

54
00:04:01,920 --> 00:04:07,200
signals travel insanely quickly latency

55
00:04:05,159 --> 00:04:12,680
of a few hundred milliseconds can still be an issue when you're connecting to a

56
00:04:09,879 --> 00:04:19,079
farway server and that's enough to wreck your gaming experience in most cases

57
00:04:16,720 --> 00:04:25,160
there's also software and even special network adapters that push through data

58
00:04:21,639 --> 00:04:28,440
packets from your game before others so

59
00:04:25,160 --> 00:04:31,479
they won't be stuck waiting around for

60
00:04:28,440 --> 00:04:33,639
other application on your

61
00:04:31,479 --> 00:04:38,400
system some routers can even be configured to push packets to your

62
00:04:35,440 --> 00:04:42,360
system first to reduce latency if a few people on your network are rudely

63
00:04:40,240 --> 00:04:48,120
deciding that now is the time that they have to watch that episode on Netflix

64
00:04:45,880 --> 00:04:53,440
now of course you're never going to get rid of latency completely I mean there's

65
00:04:51,000 --> 00:04:58,000
even eye to brain latency since your brain needs time to make sense of

66
00:04:55,720 --> 00:05:03,280
whatever the heck you're looking at the goal is to get it down to an acceptable

67
00:05:00,600 --> 00:05:08,039
level that won't leave you frustrated or with a lawsuit on your hands because

68
00:05:05,479 --> 00:05:11,600
your backup camera didn't show you that little old lady in time we've teamed up

69
00:05:10,360 --> 00:05:16,280
with Audible and they're offering everyone watching this video a chance to

72
00:05:22,720 --> 00:05:29,720
train running errands playing games that you don't need to listen to the audio to

73
00:05:27,039 --> 00:05:34,199
or whatever else you happen to be doing I've personally been listening to the

74
00:05:31,199 --> 00:05:36,440
princess diarist by Carrie fiser a

75
00:05:34,199 --> 00:05:41,759
behindth scenes recollection of her experiences filming Star Wars Episodes 4

76
00:05:39,280 --> 00:05:46,840
from Princess Leia herself and audible is offering a free Audi book with your
