Whenever mobile digital television broadcasts finally take off LG will be ready and its latest concept design -- following the autostereoscopic 3D screen shown at CES -- is the Tweet-TV pictured above. At the National Association of Broadcasters show this week it's demonstrating the prototype Android phone with a Harris MDTV antenna that also pulls in relevant tweets and displays them over the broadcast being watched.

The press release and a bigger picture follow after the break.
