How does technology developed by iBiquity
allow digital broadcasts to be transmitted over the existing
AM/FM bands? The technology used to create the powerful
digital broadcasting solution known as HD Radio is called
In-Band On-Channel Digital Audio Broadcasting.
Benefits of iBiquity Digital's HD Radio technology are:
- Enhanced sound fidelity.
- Improved reception.
- Upgraded audio quality.
- New advanced application services offering new features
and information for consumers everywhere.
- A seamless conversion process for the nation's 12,000 radio stations to move from analog to next-generation digital broadcasting.
- A unique opportunity for broadcasters and listeners to convert from analog to digital radio without service disruption, while maintaining current dial positions of existing stations and brand equity.
All of these enhancements to local AM and FM radio are designed to better serve the listening public while offering tremendous growth opportunities for broadcasters, manufacturers, retailers and automotive manufacturers.
iBiquity Digital's HD Radio technology is a method of:
- Digitally transmitting compact-disc-like quality
audio signals to radio receivers along with new wireless
data services such as station, song and artist identification,
stock and news information, local traffic and weather,
and much more.
- Using the current radio spectrum to transmit AM
and FM analog simultaneously with new higher quality
digital signals.
- Eliminating the static, hiss, pops and fades associated
with today's radio caused by conditions known as multipath,
noise and interference.
- Allowing radio broadcasters to send audio and data
content via digital signals on the existing AM/FM
bands through the more efficient use of existing bandwidth.
With iBiquity Digital's IBOC-based HD Radio technology, radio receivers and other consumer electronics will support:
- "Backward and forward" compatibility, allowing them to receive traditional analog broadcasts from stations that have yet to convert and digital broadcasts from stations that have converted. Current analog radios will continue to receive the analog portion of the IBOC-based broadcast, allowing for a smooth transition to a digital world. In fact, specific features have been designed into iBiquity Digital's IBOC technology to improve the existing analog reception during the "Hybrid Mode."
As the market reaches maturity, broadcasters will transition out of analog broadcasts and offer "all-digital mode" in much the same way that television stations did with black & white programming. As a result of our digital architecture, enhanced services such as increased data capacity, surround sound or other multi-casting solutions can be made available across this unused bandwidth.
