HD Radio™reception (U.S. models
only)
Introduction
Display when the radio is receiving an HD Radio
broadcast
NOTE
HD radio volume may fade in and out at
times due to coverage limitations.
HD radio is a brand name registered by the
Ibiquity digital corporation
1
. 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
reception, where the receiver will automati-
cally switch to the analogue signal if the digi-
tal 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 system display. The symbol
is "grayed-out" when HD Radio is in standby
mode and white when the radio is actively
receiving an HD broadcast.
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
number of listening choices through “mul-
ticasting” (consisting of a frequency's
main channel 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/
crackling due to outside influences.
How HD broadcasting works
HD Radio works similarly to conventional
radio and broadcasts of this type are availa-
ble in many areas of the United States. How-
ever, there are a few key differences:
•
Instead of transmitting one analogue sig-
nal, stations send out a bundled signal –
both analogue and digital.
•
An HD radio receiver can receive both
digital and analogue broadcasts.
