BURLINGTON In the quest to make sure all Vermonters are ready for the switchover to Digital Television (DTV), a giant rolling DTV display is making an appearance on the Church Street Marketplace in Burlington, 10 a.m. to 6 p.m., Wednesday, Sept. 24. The DTV Road Show is a large truck shaped like a giant television set. The National Association of Broadcasters has dispatched two of these rolling displays to visit every state before the Feb. 18, 2009 switch to DTV. The display gives people the chance to see a side-by-side comparison between current analog technology and the new digital T.V. system. Those who stop by will also have a chance to win some prizes, courtesy of the NAB. If your television service is provided by a cable or satellite company, youre already prepared for the switch. If, however, you receive T.V. signals through a rabbit-ear antenna or an old-style rooftop antenna, then you may need a digital converter box to continue receiving over-the-air TV. Coupons worth $40 off the cost of a digital converter box (typically a $40$70 expense) are free for the asking from the federal government. Simply call 1-888-DTV-2009 or visit the website at www.dtv2009.gov. There are an estimated 14,000 television households in Vermont that rely solely on over-the-air TV signals.
