  Gracenote Entourage is an application presented at Mobile World Congress 2012 and with its help any iDevice can recognize a movie, a TV show or a song by simply pointing the microphone at the audio source of the conversations in the respective multimedia content. Basically, we are talking about an application that offers a functionality similar to that of Shazam, but we are talking here about movies, TV shows and also about music. In the video clip above we have a short demonstration of how the application is able to recognize movies, but there we only see how it works on an Android tablet.

At its core, Gracenote Entourage features audio fingerprinting technology that allows smart phones and tablets to instantly and automatically identify movies, TV programs and music in real time by simply "listening" to short sound clips. Then, Gracenote Entourage unlocks data from the Gracenote database to create paths for TV viewers to explore related content, such as actor filmographies and advertising brands, and link to on-demand services to purchase, stream and download content that intrigues them.

  Gracenote Entourage was also presented at CES 2012, but not much fanfare was generated around it, so the manufacturers are also present at Mobile World Congress 2012. The idea is interesting, but the system must be able to recognize TV shows from various countries on next to movies or music, so it won't be widely available everywhere.
