digital tvIt was not too many years ago that your choices for television consisted of the three major networks, public television and maybe, just maybe, a local independent. Times sure have changed!

Digital Television (DTV)

    Digital Television (DTV) is a revolution in television, combining the traditional characteristics of television with the interactivity of the desktop computer. It's an over-the-air system that maintains our tradition of universal access to public service television.

        How Digital Television Works

    If you have looked at television sets at any of the big electronics retailers lately, you know that digital TV, or DTV, is a BIG deal right now in the United States. Most stores have whole areas devoted to digital TV sets. You are also hearing a lot about four other topics:
     

    • HDTV and HDTV broadcasts
    • Digital satellite services
    • Digital cable
    • DVDs and DVD players

    Unless you are in the small group of people in the United States who have purchased a DTV set, what you have in your living room is a normal analog TV that seems to be working just fine despite all the hype.
