How is digital television different from the existing analog television service?
With digital television, broadcasters are able to offer free, over-the-air television of higher resolution and better picture quality than is possible under the current mode of TV transmission. If broadcasters so choose, they can offer HDTV-television with theater-quality pictures and CD-quality sound. Alternatively, a broadcaster can offer several different TV programs at the same time, with picture and sound quality better than is available today from the analog broadcast service.
