Why are the TV broadcasters changing to digital TV?
• Congress passed legislation, beginning in 1966, mandating the change from analog to digital TV broadcast. Viewers should notice improvements in picture and sound, particularly in the case of high-definition (HDTV) broadcast. In order to receive HDTV you will need a high-definition TV set. When analog broadcast end, broadcasters will return those frequencies to the federal government. Some of the analog frequencies will be used for public safety, including communications for police and fire departments.
