There’s television technology being tested in Chicago that about a dozen people can watch right now. But the question is how many people will tune in when it’s ready for prime time? If this TV is free, and it may be, it could be a hit. Called “Mobile DTV,” it will send live signals from local TV stations to a hand-held device or a car-mounted video monitor. The signal stays sharp as you drive along the Kennedy Expressway or ride the “L” to work. Our current mobile options come from wireless phone carriers and do not offer live, local channels.
