YOUTUBE Copyrights:
How YouTube identify copyrighted material is uploaded to
their site?
Whether We are an artist, a
technologist, a lawyer or a fan, the handling of copyright directly
impacts our life. Rights management is no longer simply a question of
ownership, it's a complex web of relationships and a critical part of
our cultural landscape. YouTube cares deeply about the rights of content owners, but
in order to give us choices about what they can do with copies, mashups
and more, they need to first
identify when copyrighted material is uploaded to our site. Let's look at
a specific video so we can see how it works. Two years ago, recording
artist Chris Brown released the
official video for his single "Forever." A fan saw it on TV, recorded
it with her camera phone, and
uploaded it to YouTube. Because Sony Music had registered Chris Brown's
video in their Content ID system, within seconds of attempting to
upload the video, the copy was detected, giving Sony the choice of
what to do next. But how do they
know that the user's video was a copy? Well, it starts with content owners delivering
assets into our database, along with a usage policy that tells us
what to do when we find a match. They compare
each upload against all of the reference files in their database.
YouTube's Content ID system addresses all of these cases. But
the system only works through the participation of rights owners. If
we have content that others are uploading to YouTube, we should register
in the Content ID system, and then we'll have the choice about how
your content is used. And think carefully about the policies that we
attach to that content. By simply blocking all reuse, we'll miss out
on new art forms, new audiences, new distribution channels, and new revenue streams.
This heat map is going to show you how
the brain of the system works. Here we can see the original reference file being
compared to the user generated content. The system compares every moment of
one to the other to see if there's a match. This means that they can
identify a match even if the copy used is just a portion of the original
file, plays it in slow motion and
has degraded audio and video quality. And they do every time that a
video is uploaded to YouTube. And that's over 20 hours of video every
minute. When they find a match, they apply the policy that the rights
owner has set down and the scale and the speed of this system are
truly breathtaking.
They are not
just saying about a few videos, they’re talking
about over 100 years of video every day, between new uploads and the legacy scans will regularly do
across all of the content on the site. When they compare those hundred
years of video, they're comparing it against millions of reference
files in our database. It would be like 36,000 people staring at
36,000 monitors each and every day, without so much as a coffee break.Now, what do we do when we find a match? Well, most rights
owners, instead of blocking, will allow the copy to be published. And
then they benefit through the exposure, advertising, and linked sales. Remember Chris Brown's video
"Forever"? Well, it had its day in the sun and then it dropped
off the charts, and that looked like the end of the storyBy empowering
choice, they can create a culture of opportunity. And all it took to
change things around was to allow
for choice through rights identification. So why has no one ever solved
this problem before? It's because
it's a big problem, and it's complicated and messy. It's not uncommon
for a single video to have multiple rights owners. They're musical
labels. There're multiple music publishers. And each of these can
vary by country. There're lots of cases where they have more than one
work mashed together. So we have to manage many claims to the same
video.
But it's not just about dollars and
impressions. Just look at all the joy that was spread through
progressive rights management and new technology. And they think we
can all agree that joy is definitely an idea worth spreading
