What is HD Radio?

HD Radio represents the next generation in AM and FM broadcast technology. HD Radio is the pure digital transmission medium that greatly improves the sound quality of radio broadcasts, virtually eliminates static, hiss, pops and fades; upgrades the data display capabilities on receivers and opens up the opportunity for multicasting: broadcasting multiple high-quality channels on each frequency.


What are the benefits to the listener?

HD Radio allows you to continue listening to current analog broadcasts while enjoying the features of digital broadcasts. You'll be able to drive around -- behind buildings, inside parking lots, through rugged terrain -- without hearing the interference and static that you might be experiencing now. AM broadcasts will sound as good as today's FM stereo broadcasts, and FM will sound like CDs. You'll also have access to additional format choices when stations multicast.


How does HD Radio work?

HD Radio stations transmit a data stream within the same licensed bandwidth used to transmit their analog broadcasts. This data stream contains the programming for the station, data for the receiver display, and any additional multicast programming.

Stations will bundle the analog and digital signals with data: weather, traffic, artist name, song title, name of the talk show host, etc. The digital signal is simultaneously transmitted along with the analog signal. You can use your current antenna to receive both your analog signal and your digital HD Radio signal. HD Radio receivers already on the market are designed to sort through reflected (multipath) signals with crystal clear reception. The simultaneous transmission of analog and digital is compatible with today's radios and new digital HD Radio receivers.


Do I need a new receiver in order to enjoy HD radio broadcasts?

Yes, you'll need an HD Radio receiver to enjoy HD Radio broadcasts. This receiver will be able to pull in radio stations broadcasting in digital and analog, and it can display text data sent by the station. A number of high-profile receiver manufacturers have committed to launching HD Radio receivers, including ADA , Alpine, Boston Acoustics, Day Sequerra, JVC, Kenwood, Panasonic, Polk Audio, Radiosophy, Rotel and Sony.
