Unscramble the Blue Letters


Let's look at a specific video so you can see how it works. Two yreas ago, rerodincg artist Chris Brown released the oifcifal video of his single "Forever." A fan saw it on TV, reocdred it with her camera phone, and uploaded it to youubte. Because Sony Music had registered Chris Brown's video in our Content ID system, within seconds of attempting to ulpaod the video, the copy was detected, giving Sony the choice of what to do next.

But how do we know that the user's video was a copy? Well, it sttras with content owners delivering atesss into our database, along with a usage policy that tells us what to do when we find a mctah. We compare each upload against all of the reference files in our database. This heat map is going to show you how the brain of the system works. Here we can see the orignail reference file being compared to the user generated content. The ssyetm capomers every moment of one to the other to see if there's a match. This means that we can identify a match even if the copy used is just a portion of the original file, plays it in slow motion and has dgreaedd audio and video quality. And we do this every time that a video is uploaded to YouTube. And that's over 20 huors of video every minute. When we find a match, we apply the policy that the rhgits owner has set down.

Original Text


Let's look at a specific video so you can see how it works. Two years ago, recording artist Chris Brown released the official video of 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 our 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 we 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. We compare each upload against all of the reference files in our database. 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 we 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 we do this every time that a video is uploaded to YouTube. And that's over 20 hours of video every minute. When we find a match, we apply the policy that the rights owner has set down.
