iBiquity HD Radio is a proprietary digital broadcast radio format transmitted in North America, usually as sidebands on analog carriers. This is the AMAmplitude Modulation band implementation of HD Radio. This system exists on both FM and AM Bands. This system was developed by iBiquity, which has been acquired by DTS in 2016.


Characteristics[edit]

HD Radio is an OFDMOrthogonal Frequency-Division Multiplexing digital broadcast that usually coincides with an analog signal, but in the AMAmplitude Modulation band you may find signals that are purely HD Radio format, in a similar fashion as DRM. HD radio can also have multiple soundtracks, adding to the number of radio stations you can listen to on a given frequency channel.

Currently, hybrid implementations employ IBOCIn-Band On-Channel (IBOC) is a hybrid method of transmitting digital radio and analog radio broadcast signals simultaneously on the same frequency. techniques by adding extended subcarriers to existing analog transmissions so that both analog and digital formats can be supported. In the future it is hoped that this will allow a gradual segway into fully-digital radio broadcasts.

For AMAmplitude Modulation IBOCIn-Band On-Channel (IBOC) is a hybrid method of transmitting digital radio and analog radio broadcast signals simultaneously on the same frequency., each HD Radio sideband is 5kHz wide.

Samples[edit]

The sound sample is the upper side band of the AMAmplitude Modulation HD Radio transmission.

Frequencies[edit]

US AMAmplitude Modulation Broadcast Band (535 kHzKiloHertz (kHz) 10^3 Hz - 1700 kHzKiloHertz (kHz) 10^3 Hz)

HD Radio is also used in Canada and Mexico.

Decoding Software[edit]

Since HD Radio utilizes a proprietary codec, owned by iBiquity, there are no known software-based decoders for HD Radio at this time.
