"Digital broadcast will vastly improve free TV viewing," said Graham Jones, the director of communications engineering for the science and technology department of the National Association of Broadcasters. This means that many consumers will be able to access HD content without subscribing to a pricey cable package. For example, all the major networks-ABC, CBS, Fox, and NBC-transmit some shows over the air in HD. In some cases if consumers have a high-definition TV, they'll even be able to get some HD channels for free.

In fact, many broadcasters have already launched three or four separate digital channels, each carrying programming of interest to diverse communities. But with digital signals, broadcasters can transmit multiple channels at once. Using analog signals, broadcasters can only transmit one channel of content at a time.
