New gadgets bring over-the-air TV to mobile devices

As usual, there were plenty of giant TVs at the Consumer Electronics Show in Las Vegas last week. But I’ve seen enough forty-acre screens, and so have you. How about something a little smaller?

It’s called Mobile DTV, a technology that lets viewers receive over-the-air television broadcasts on their mobile devices. Instead of wasting your cellular data plan on Netflix movies, get free video from the airwaves, like Grandpa used to do. Mobile DTV works pretty well, too, but for now it is much too limited to catch on with consumers.
