When asked for "The Dark Knight Rises," the TV showed that it was available for rental or purchase on-demand through the Vudu online video app and brought up that app on the TV.
Another feature demonstrated on an LG TV was a way to mirror what's on your smartphone or tablet with the TV. Using what's known as "near-field communications," an attendant touched his Android phone to a kind of sticky pad that was stuck onto the TV stand. After interacting with the chip inside the pad, the phone was paired with the TV. The phone then brought up two arrows, one for "Phone to TV" and the other "TV to Phone."
By swiping up for "Phone to TV," whatever was on the phone then showed up on the big screen. Swiping the other way brought out a set of controls for using the phone like a remote control.
