The switch to digital TV promises several benefits:
• Viewers should notice improvements in picture and sound quality, particularly in the case of high-definition (HDTV) broadcasts. (To get the full effect, you’ll need a high-definition set, and the broadcaster and, if applicable, cable or satellite provider must provide a high-definition signal.)
• Digital transmissions make more efficient use of the broadcast spectrum, leaving more of the airwaves available for additional channels or interactive data services.
• When analog TV broadcasts end, broadcasters will return those frequencies to the federal government. Some have been pre-allocated to public-safety uses, including communications systems for police and fire departments. The government is likely to auction off much of the rest to wireless companies and others for commercial uses.
