From an historical point of view, the content recognition has always presented an undoubted interest. The broadcasters have obvious needs of broadcast certificate for the CSA, for advertisers, for any copyright organization, both for legal reasons (language quota, speaking time, ...) and monetary reasons. Reversely, these same actors will want to independently validate the declarative statements of the media. Finally, in an increasingly competitive world, the possibility of having an automated analysis of competitors is raising more and more interest. From a technical point of view, you will see that the audio fingerprint technology can today cover other business cases such as the identification of duplicates in the audio libraries, effective audience measurement etc. Until recently, the barriers were technical. This MasterClass will summarize the different content recognition technologies, their advantages and limitations and especially what you can expect today from an available, fully automated and highly accurate solution like SoundID. This Masterclass is aimed at radios (music department, advertising department, ...), advertising agencies as well as content providers and labels.
