A look at the Gracenote TrackID service on Sony TVs.
In 2011 Internet-connected TVs from Sony have a new feature similar to Shazam found on smartphones. The service, which Sony is branding TrackID, relies on a "fingerprinting" technology powered by Gracenote--a company formerly known as CDDB and bought by Sony in 2008. The way it works is simple: anytime you hear a song, or snippet of music, on your TV, you can hit the "TrackID" button to attempt to identify it.
Choosing to search within apps leads to a choice of searching across Sony's Bravia Video services (excluding Netflix, Amazon VOD, YouTube, and Hulu Plus) or a "video search," which at the moment provides only text-based results like biographical information--a sort of "IMDB lite."
