What is HD Radio?

HD Radio is an upgrade of the way AM and FM radio signals are transmitted, from analog to digital signals. Sounds neat. But what does that mean for us listeners?

  • FM radio with near CD-quality sound
  • AM radio that sounds as good as traditional FM
  • No more static, pops, crackles or fades
  • Transmission of additional information, such as song titles and artists
  • Increased listening options with multicasting
  • Tagging a song for later purchase through the iTunes® Store
FM radio with near CD-quality sound

Digital technology allows Meyer Communications to transmit more information in the same radio wave. Primarily, this means higher quality sound. So much more so that FM transmissions sound nearly as good as CDs.

AM radio that sounds as good as FM Stereo
AM radio uses smaller sections of bandwidth than FM. There is not enough bandwidth for HD Radio to give AM stations the same CD-quality signal as FM stations. But there is enough room to give AM stations clarity equivalent to current analog FM stereo radio. This boost in sound quality is expected to make AM radio a viable alternative to FM, which means more options for listeners.
No more static, pops, crackles or fades
The digital signal is less vulnerable to reception problems. The radio tuner's digital processors eliminate the static, pops, hisses, and fades caused by interference.
Should you lose the digital signal for some reason (obstructing terrain, nearing the edge of the broadcast area, etc.), HD Radio technology defaults back to analog mode, similar to the way current radios switch from stereo to mono mode when receiving a weak signal. The radio sacrifices detail in an effort to boost reception.
Transmission of additional information
Another benefit of digital radio is Meyer Communications ability to transmit additional information along with the music signal. Typically, this takes the form of scrolling text on your receiver's display, such as a song's artist and title, station call letters, and advertising information. If you're listening to a news show, financial updates can be transmitted to your radio. And stations can include local and regional information, such as weather updates or even traffic alerts.
Questions and Answers

Q: What is HD Radio?
A: The term "HD Radio" is iBiquity Digital Corporation's trademarked name for their digital audio broadcasting technology, which has become the IBOC standard adopted for the United States.

Q: What's IBOC?
A: IBOC — In Band On Channel — derives its name from the kind of digital signal being broadcast. IBOC signals use the same AM and FM bandwidth as a station's analog signal ("in band"). The digital information is contained within the station's signal ("on channel").

Q: Is HD Radio technology the same as HDTV?
A: Only in the sense that they're both digital signals. Television's move to HDTV is mandated by the federal government. HDTV will soon completely replace current analog television broadcasts. On the other hand, radio stations are voluntarily adding HD Radio technology to their regular broadcasts. Stations will continue using the same AM and FM frequencies they do now.

Q: What does "HD" stand for?
A: Originally, the initials stood for "hybrid-digital," because the digital signals were carried with the analog wave. According to iBiquity Digital Corporation, that's been changed, and the letters "HD" now don't stand for anything. Some articles and news stories have erroneously assumed that "HD" stands for "high definition," which has contributed to the confusion between HD Radio technology and High-definition TV.

Q: How is HD Radio different than current FM and AM radio?
A: Because they're digital, HD Radio signals aren't subject to atmospheric interference the way current FM and AM signals are. Background crackle and hiss are eliminated. The effect is similar to the difference between CDs and records. The digital CD signal is free of the surface noise that's always present on LP playback.

Q: How can I find out if my local station is broadcasting digitally?
A: As stations add HD Radio capability to their service, they generally publicize the fact. iBiquity Digital also maintains a site that lists which stations are broadcasting with HD Radio signals.

Q: My radio isn't compatible with HD Radio broadcasts. Will it become obsolete?
A: Partially. Stations broadcasting with HD Radio technology will continue to simulcast their AM or FM analog signals, so you'll be able to enjoy the same stations as before. Without an HD Radio tuner, though, you'll miss out on the digital-only multicast channels stations will now be offering.

Q: What is multicasting?
A: An HD Radio signal can be subdivided to send out two or more different kinds of programming simultaneously. When a station does this, it is multicasting.

Q: What is HD2?
A: HD2 is the term multicasting stations are using for their secondary digital-only channel. Some stations are using this second channel to offer more specialized programming, such as Latin Hits, Classical Opera, and Electronica.

Q: Can all HD Radio tuners get these extra channels?
A: Multicasting was developed after the first generation of HD Radio tuners hit the market. While all HD Radio tuners will pick up the station's primary digital channel, only radios that are designated multicast-capable will be able to pick up HD2 and any additional subchannels. Multicasting capability has since become a standard feature on HD Radio tuners. At this point, most HD Radio tuners on the market can receive multicast channels.

Q: Satellite radio requires a monthly subscription fee for their digital broadcasts. What do HD Radio broadcasts cost?
A: Like current FM and AM radio, HD Radio broadcasts are free to the public. Your only expense is the purchase of an HD Radio tuner.

Q: Is the coverage area of my station's HD Radio signal identical to that of their current signal?
A: Although the coverage area will be similar, there can be areas where only the analog signal can be heard, and conversely, areas where only the HD Radio digital signal can be tuned in. Because terrain obstacles affect analog and digital signals in slightly different ways, there's no sure-fire way to predict reception, especially on the outskirts of a station's coverage area.

Q: What happens if I lose the HD Radio signal?
A: If your HD Radio tuner loses the station's digital signal, it will automatically switch over to the analog signal broadcast at the same frequency. There may be a slight break in the sound when this happens. When the tuner is back in range of your station's HD Radio signal, it will automatically go back to the digital broadcast.

Q: I see a lot of car radios use the term "HD Radio ready." What does that mean?
A: An HD Radio ready car radio — or "head unit" — can play HD Radio signals, but requires connection to a separate HD Radio tuner. If the radio is a factory stereo, you'll have to get the tuner from the dealer. If you have a brand-name stereo, we probably have the add-on tuner you need.

Q: Can I only hear HD Radio in the car?
A: No. Several manufacturers offer stand-alone tabletop radios that have built-in HD Radio tuners. There are also a few home theater and stereo receivers with HD Radio tuners available as well. The first add-on component HD Radio tuner for advanced audio/video systems came to market in 2007.

To get an HD radio, you will need to visit your local BEST BUY dealer and pick one up today!
Just look for the HD Radio logo on the unit.
