Definition: HD Radio is a digital radio broadcast service that offers higher quality audio, clear, static-free reception, more programming choices and text-based information, such as artist, title, weather information and multicasting, which is the ability to receive multiple programs on the same radio frequency (example 97.1-1, 97.1-2,97.1-3, etc.) HD Radio requires a special tuner to receive the broadcast. The FCC approved HD Radio in 2002 as the only AM and FM digital broadcast system operating in the US.
Examples: A HD Radio broadcast improves the sound quality of conventional AM and FM radio broadcasts.
