so that’s how that’s done

Audible Magic analyzes clips by listening to their soundtrack, including the musical score, the dialogue and the sound effects. Working with Hollywood studios and record companies, it has compiled a library of audio files, including about 6 million individual music recordings.

When a user uploads a video onto MySpace, for instance, that clip is sent to Audible Magic for a test. Audible Magic’s system checks if the clip has a soundtrack that is similar to something in its library. If there is a match, the video is flagged and cannot be uploaded. The examination takes a few seconds to a minute, depending on how closely the site wants to monitor, and it occurs at the same time the video is processed to be displayed on the site.

In addition to MySpace, online video sites such as Grouper, Break.com and GoFish also use Audible Magic, which can process about 5 million to 10 million files a day. The company, which is also developing video tracking technology, has seen an increased interest as the online video phenomenon grows. “A lot of the sites are worried about being sued, too,” Audible Magic CEO Vance Ikezoye said.

I was wondering. I’ve also noticed that google video loves text embedded in the video.
