Digital TV transition takes effect Tuesday night

If you are using an analog TV and antenna to watch television, you will need to hook up a digital converter box in order to keep your picture from Tuesday night. Digital television (DTV) is the sending and receiving of moving images and sound by discrete (digital) signals, in contrast to the analog signals used by analog TV. The first country to make a wholesale switch to Digital Over-the-Air (terrestrial) broadcasting was the Netherlands, in 2006. This was followed by Finland and Sweden in 2007.
