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 or 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 to her 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.
