HD radio is a brand name registered by the Ibiq-
2
uity digital corporation . They are the developer
of a broadcasting technology called IBOC or In
Band On Channel, which refers to the method
of transmitting a digital radio broadcast signal
centered on the same frequency as the AM or
FM station's present frequency.

The IBOC system is referred to as a "hybrid"
since it is both analogue and digital. During
hybrid operation, receivers still continue to
receive the analogue (non-digital) signal. HD
radio receivers incorporate both modes of recep-
tion, where the receiver will automatically switch
to the analogue signal if the digital signal cannot
be decoded or is lost by the receiver.
When you have tuned to an HD Radio station, the
symbol will appear in the infotainment sys-
tem display. The symbol will be displayed in dif-
ferent colors:
•
Grayed-out symbol: HD Radio is in standby
mode
•
White symbol: the radio is actively receiving
an HD broadcast
•
Orange symbol: the radio is receiving an
HD broadcast with digital sound
More information about HD radio and IBOC can
be found on Ibiquity's website, www.hdradio.com
and www.ibiquity.com.
Benefits of digital broadcasting
•
Better sound (FM sounds near CD quality
and AM as analogue FM).
•
Some FM frequencies offer a greater num-
ber of listening choices through "multicast-
ing" (consisting of a frequency's main chan-
nel and any sub-channels that may also be
available on that particular frequency. See
also the section "Sub-channels" below).
•
When receiving a digital signal there is no
multipath disturbance or hisses/pops/crack-
ling due to outside influences.
How HD broadcasting works
HD Radio works similarly to conventional radio
and broadcasts of this type are available in many
areas of the United States. However, there are a
few key differences:
•
Instead of transmitting one analogue signal,
stations send out a bundled signal – both
analogue and digital.
•
An HD radio receiver can receive both digital
and analogue broadcasts. Depending on the
terrain and location of the vehicle (which will
influence the signal strength), the receiver
will determine which signal to receive.
