The LG Cafe Phone, which is also known as the SU420, has surfaced in South Korea and is the world's first mobile to comply with version 2.0 of the DMB mobile TV standard, allowing users to access interactive TV everywhere.
Most of the range topping smartphones in Korea feature the ability to accept mobile TV broadcasts, but none can boast the same level of interactivity as the LG Cafe Phone.
The interactivity is made possible because the phone's internet connection is used in conjunction with the received broadcast.
This lets the user view information about products that they might see in an advert or during a show, such as how much they cost and where they can buy them.
The LG SU420 has a 3.2 inch touchscreen display, a three megapixel camera and the usual selection of connectivity options, including HSDPA and Wi-Fi.
So far the price of the SU420 is not known, but network provider SK Telecom is going to be stocking the phone for its Korean customers.
Since mobile TV broadcasts are not available in the UK, there is no news as to whether LG will bother bringing the Cafe Phone over here, but it could release a stripped-down version in the future.
