2000
00:17
or maybe you're watching this talk in some other time or place,
1
17260
3000
00:20
you are a participant in the digital rights ecosystem.
2
20260
3000
00:23
Whether you're an artist, a technologist,
3
23260
2000
00:25
a lawyer or a fan,
4
25260
2000
00:27
the handling of copyright directly impacts your life.
5
27260
3000
00:30
Rights management is no longer
6
30260
2000
00:32
simply a question of ownership,
7
32260
3000
00:35
it's a complex web of relationships
8
35260
2000
00:37
and a critical part of our cultural landscape.
9
37260
3000
00:40
YouTube cares deeply about the rights of content owners,
10
40260
3000
00:43
but in order to give them choices about what they can do
11
43260
2000
00:45
with copies, mashups and more,
12
45260
3000
00:48
we need to first identify
13
48260
2000
00:50
when copyrighted material is uploaded to our site.
14
50260
3000
00:53
Let's look at a specific video so you can see how it works.
15
53260
3000
00:56
Two years ago, recording artist Chris Brown
16
56260
2000
00:58
released the official video of his single "Forever."
17
58260
3000
01:01
A fan saw it on TV,
18
61260
2000
01:03
recorded it with her camera phone,
19
63260
2000
01:05
and uploaded it to YouTube.
20
65260
3000
01:08
Because Sony Music had registered Chris Brown's video
21
68260
3000
01:11
in our Content ID system,
22
71260
2000
01:13
within seconds of attempting to upload the video,
23
73260
2000
01:15
the copy was detected,
24
75260
2000
01:17
giving Sony the choice of what to do next.
25
77260
3000
01:20
But how do we know that the user's video was a copy?
26
80260
3000
01:23
Well, it starts with content owners
27
83260
2000
01:25
delivering assets into our database,
28
85260
2000
01:27
along with a usage policy
29
87260
2000
01:29
that tells us what to do when we find a match.
30
89260
3000
01:33
We compare each upload
31
93260
2000
01:35
against all of the reference files in our database.
32
95260
3000
01:38
This heat map is going to show you
33
98260
2000
01:40
how the brain of the system works.
34
100260
2000
01:42
Here we can see the original reference file
35
102260
2000
01:44
being compared to the user generated content.
36
104260
3000
01:48
The system compares every moment
37
108260
2000
01:50
of one to the other to see if there's a match.
38
110260
2000
01:52
This means that we can identify a match
39
112260
2000
01:54
even if the copy used is just a portion of the original file,
40
114260
3000
01:57
plays it in slow motion
41
117260
2000
01:59
and has degraded audio and video quality.
42
119260
3000
02:02
And we do this every time
43
122260
2000
02:04
that a video is uploaded to YouTube.
44
124260
2000
02:06
And that's over 20 hours of video every minute.
45
126260
3000
02:09
When we find a match,
46
129260
2000
02:11
we apply the policy that the rights owner has set down.
47
131260
3000
02:15
And the scale and the speed of this system
48
135260
3000
02:18
is truly breathtaking.
49
138260
2000
02:20
We're not just talking about a few videos,
50
140260
3000
02:23
we're talking about over
51
143260
2000
02:25
100 years of video every day,
52
145260
3000
02:28
between new uploads and the legacy scans
53
148260
2000
02:30
we regularly do across all of the content on the site.
54
150260
3000
02:34
When we compare those hundred years of video,
55
154260
2000
02:36
we're comparing it against millions
56
156260
2000
02:38
of reference files in our database.
57
158260
2000
02:40
It would be like 36,000 people
58
160260
2000
02:42
staring at 36,000 monitors
59
162260
3000
02:45
each and every day, without so much as a coffee break.
60
165260
3000
02:48
Now, what do we do when we find a match?
61
168260
3000
02:51
Well, most rights owners, instead of blocking,
62
171260
3000
02:54
will allow the copy to be published.
63
174260
2000
02:56
And then they benefit through the exposure,
64
176260
2000
02:58
advertising and linked sales.
65
178260
3000
03:01
Remember Chris Brown's video "Forever"?
66
181260
2000
03:03
Well, it had its day in the sun and then it dropped off the charts,
67
183260
2000
03:05
and that looked like the end of the story,
68
185260
3000
03:08
but sometime last year, a young couple got married.
69
188260
2000
03:10
This is their wedding video.
70
190260
2000
03:12
You may have seen it.
71
192260
2000
03:14
(Music)
72
194260
2000
03:16
What's amazing about this is,
73
196260
2000
03:18
if the processional of the wedding was this much fun,
74
198260
2000
03:20
can you imagine how much fun the reception must have been?
75
200260
2000
03:22
I mean, who are these people?
76
202260
2000
03:24
I totally want to go to that wedding.
77
204260
3000
03:27
So their little wedding video went on
78
207260
2000
03:29
to get over 40 million views.
79
209260
3000
03:32
And instead of Sony blocking,
80
212260
2000
03:34
they allowed the upload to occur.
81
214260
2000
03:36
And they put advertising against it
82
216260
2000
03:38
and linked from it to iTunes.
83
218260
2000
03:40
And the song, 18 months old,
84
220260
3000
03:43
went back to number four on the iTunes charts.
85
223260
3000
03:46
So Sony is generating revenue from both of these.
86
226260
3000
03:49
And Jill and Kevin, the happy couple,
87
229260
2000
03:51
they came back from their honeymoon
88
231260
2000
03:53
and found that their video had gone crazy viral.
89
233260
2000
03:55
And they've ended up on a bunch of talk shows,
90
235260
3000
03:58
and they've used it as an opportunity to make a difference.
91
238260
2000
04:00
The video's inspired over 26,000 dollars in donations
92
240260
3000
04:03
to end domestic violence.
93
243260
2000
04:05
The "JK Wedding [Entrance] Dance" became so popular
94
245260
3000
04:08
that NBC parodied it on the season finale of "The Office,"
95
248260
3000
04:11
which just goes to show,
96
251260
2000
04:13
it's truly an ecosystem of culture.
97
253260
3000
04:16
Because it's not just amateurs borrowing from big studios,
98
256260
3000
04:19
but sometimes big studios borrowing back.
99
259260
3000
04:22
By empowering choice, we can create a culture of opportunity.
100
262260
3000
04:25
And all it took to change things around
101
265260
2000
04:27
was to allow for choice through rights identification.
102
267260
3000
04:30
So why has no one ever solved this problem before?
103
270260
3000
04:33
It's because it's a big problem,
104
273260
2000
04:35
and it's complicated and messy.
105
275260
2000
04:37
It's not uncommon for a single video
106
277260
2000
04:39
to have multiple rights owners.
107
279260
2000
04:41
There's musical labels.
108
281260
2000
04:43
There's multiple music publishers.
109
283260
2000
04:45
And each of these can vary by country.
110
285260
2000
04:47
There's lots of cases
111
287260
2000
04:49
where we have more than one work mashed together.
112
289260
2000
04:51
So we have to manage many claims
113
291260
2000
04:53
to the same video.
114
293260
2000
04:55
YouTube's Content ID system addresses all of these cases.
115
295260
3000
04:58
But the system only works through
116
298260
2000
05:00
the participation of rights owners.
117
300260
2000
05:02
If you have content that others are uploading to YouTube,
118
302260
3000
05:05
you should register in the Content ID system,
119
305260
2000
05:07
and then you'll have the choice
120
307260
2000
05:09
about how your content is used.
121
309260
2000
05:11
And think carefully about the policies that you attach to that content.
122
311260
3000
05:14
By simply blocking all reuse,
123
314260
2000
05:16
you'll miss out on new art forms,
124
316260
2000
05:18
new audiences,
125
318260
2000
05:20
new distribution channels
126
320260
2000
05:22
and new revenue streams.
127
322260
2000
05:24
But it's not just about dollars and impressions.
128
324260
3000
05:27
Just look at all the joy
129
327260
2000
05:29
that was spread through progressive rights management
130
329260
2000
05:31
and new technology.
131
331260
2000
05:33
And I think we can all agree that joy is definitely an idea worth spreading.
132
333260
3000
05:36
Thank you.
133
336260
2000
05:38
