Bundle analog and
digital audio signals (with textual data, such as artist and song
information and more)
The signal will be
compatible with HD Radio receivers and analog radios
HD Radio technology is a
digital radio standard developed by iBiquity Digital and recognized
by the U.S. Federal Communications Commission (FCC)
How does it work?
Instead of sending out one
analog signal, stations send out a bundled signal – both analog and digital.
Because it is digital, textual data such as traffic, stock info and song
titles can be sent out, as well
The digital signal layer is
compressed
HD Digital Radio supports
CD-quality sound as well as song titles and artist names. And because the
digital signal piggybacks onto a conventional broadcast signal, it is free
to the listener
HD Radio sends more information
over the same radio frequency by digitizing the signal
The extra bandwidth of an HD
Radio signal leaves room for completely separate channels operating on the
same frequency
Multipath interference, caused
by the signal reflecting off of buildings, is ignored by the digital radio,
which is able to discern the true signal and ignore interference
The three-layered
signal is transmitted from the radio station's upgraded digital
transmitter
What do I need?
An HD Radio Receiver, yes,
that's it!
Okay, how much will it cost me?
Reception is free, with no
subscription costs
The cost for the station is
about $200,000 to convert over to HD Radio Transmission
