What is HD Radio?

HD Radio is a digital radio standard developed by iBiquity Digital and recognized by the U.S. Federal Communications Commission (FCC). It works the same way that traditional analog transmits, except that the audio is digital formatted and transmitted as a continuous digital data stream along with the analog signal. Radio stations send out the analog and digital signals on the same broadcast frequency, along with the signals for the text data. On the listener end, the signals are received and decoded. An HD Radio receiver picks up both the digital radio transmission with its accompanying text as well as the existing analog transmission. If you have a HD Radio receiver you will still be able to listen to stations that do not broadcast HD. And your existing analog receivers will still continue to receive the analog signals from broadcaster. A big difference between digital radio and digital television is that radio will continue to broadcast both analog and digital signals.
