LG partners with Cognitive Networks
 

There's a problem with Smart TVs -- they really aren't all that smart. While having WiFi-equipped sets that can run apps and stream content from the web might make them seem smart, TV's don't actually know what content is onscreen when they're showing, you know, regular broadcast television. (Which is still what those TVs are most used for.) Cognitive Networks, however, has figured out how to make those televisions aware of what's happening onscreen, and LG is the first manufacturer to leverage the technology with its LivePlus service. LivePlus was first revealed at the launch of Showtime's Sho Sync app last week, but the Cognitive Networks' technology powering LG's platform can do so much more than just display character backgrounds, trivia and other info. To fully appreciate the breadth of possibilities the tech provides, however, it's important to know how it actually works.
