From Wikipedia:

HD Radio is the trademark for iBiquity's in-band on-channel (IBOC) digital radio technology used by AM and FM radio stations to transmit audio and data via a digital signal in conjunction with their analog signals. It was selected by the United States Federal Communications Commission (FCC) in 2002 as a digital audio broadcasting method for the United States,[1][2] and is the only digital system approved by the FCC for digital AM/FM broadcasts in the United States.

I was also interested in the details of this feature and went searching. Here's what I found:

From the XTS owner's manual:

HD Radio Technology

HD Radio™ Technology is a free service with features such as static-free sound, more programming choices on local FM HD2, HD3, and higher, and on-screen information such as artist and song title.

HD Radio Technology Channel Access

To access HD Radio channels:
1. Tune the radio to the channel.
If the channel is broadcasting
HD Radio Technology, the radio
will automatically switch to digital
audio, indicated with an HD logo.

HD Radio channels can be saved
as favorites. Songs can be tagged
for download to a connected
iPhone® or iPod touch.

If the HD Radio signal loses
reception while listening to channel
HD1, the radio will go back to the
main non-HD Radio channel.
