We will share on this page details- What is HD Radio?
Nowadays, HD Radio Becomes is one of the most important devices in our life like other devices, due to the multi-functions that you find in it, So what should you know about HD Radio, and how can you benefit from it?
HD radio tool enables AM and FM radio stations to broadcast their programs digitally – a huge technological leap from analog broadcasting in the past. In a recent study, HD Radio partnered with Nielsen to study the effect of various in-car platforms on awareness and advertising, High-quality radio technology appeared in America through iBiquity, which developed this technology and became widespread throughout America. Current FCC regulations also require stations to broadcast the same audio signal at the same time in analog mode, so if the primary digital signal is lost, the HD radio receiver will revert to the analog signal thus ensuring continuous operation.
The FM HD radio signal has a larger spectrum area than the AM HD radio signal since more bandwidth is allocated to the FM channel. Therefore, FM HD radio signals can operate at higher data rates than AM HD radio signals. This higher data rate can be split into parts to allow additional audio channels to be carried over the frequency.
A presentation about HD Radio
The technology transmits digital and analog waves, but the digital waves do not only carry high-quality sound (the sound comes with the quality and clarity of the sounds that come on the CD), but this digital wave transmits text data such as information about the name of the program that is broadcast by the radio or the weather and finally this technology allows you to be able The radio broadcasts two programs simultaneously, and the user can choose what he wants to listen and this feature is called (Multicasting), for example ( The radio can broadcast music and news at the same time).
And then these waves are received in radios that support high-quality technology, and several devices have appeared from several major companies such as Sony, Kenwood, JVC … etc.
For HD AM broadcasts, stations can choose broadcast rates between 40 and 60 kbps. Most stations use a bit rate of 40 kbps because this method is more powerful and less likely to cause losses due to signal strength issues. In theory, increased AM bandwidth helps ensure FM radio quality for AM radio.
How does HD radio work?
every North American FM radio station is assigned a specific range of frequencies that it can use to broadcast its content. Analog frequency limits for an FM radio station are 88.1 to 107.9MHz, and each station has a bandwidth of 200kHz for both mono and stereo signal transmission. The Federal Communications Commission (FCC) in the United States and Industry Canada (IC) controls the standards and handling of licensing in their respective countries.
On the technical side, with a bandwidth of 20 MHz, there is room for 100 stations in the 88 and 108 MHz bands to broadcast simultaneously within the same area. In fact, some cities have this number of radio stations. The FCC and the IC are of the view that the radio station’s broadcast frequencies are far apart enough that it does not interfere. in addition to that, stations broadcasting at the same carrier frequency need a transmitter far enough from a similar station so that the signals do not interfere with the target market.
How to get HD Radio at your home?
if you want to get HD Radio into your home, you simply need to choose a home receiver capable of receiving HD Radio, Like Sangean HDR-18, or use a different HD Radio receiver as an audio component connected to your existing home receiver. The HD Radio Web site has a listing of HD Radio-available devices, as good as a station listing, so you can explore what HD Radio shows in your location
How can we benefit from HD RADIO?
This device provides many features that benefit its user, such as
- No subscription fees (as they are free !!)
- No smartphone is needed (so no data is used)
- No more stickiness, pops, crackles, or fading
- FM radio sounds as good as a CD
- AM Radio sounds just as good as a traditional FM radio
- Showed information, including station ID information, song titles, artists, weather, traffic, and emergency alerts
- Increase listening options with station multicasting
- 3 car stereo head units
- A difference you can really hear
When we asked Kevin, our social media expert if he’d like to take a tour and give the local HDR Radio stations a listen – and have a delicious burger. So we searched for HD radio stations available in the city, plugged them into the radio presets, and headed out of town.
– No more persistence, pops, crackles, fading .. and no monthly payment
The digital signal is less prone to reception problems. Digital radio tuner processors eliminate static, persistent organic pollutants, hissing, and fade-out caused by interference. You just hear the clear, clean, and rich sound. If the digital signal is lost for some reason (blocking the terrain, approaching the edge of the broadcast area, etc.), HD Radio reverts to analog mode, similar to the way non-HD radio receivers switch from stereo mode to mono when receiving a Weak signal. And like analog radio, HD Radio is free without a subscription.
How to get an HD radio in the Car?
Many car drivers prefer to connect their vehicles with HD Radio to benefit from its amazing features! So what should you do to get HD Radio in your car?
You can add an HD ”Car Connect” radio tuner to almost any car audio system, whether it’s a factory stereo or a brand-name CD receiver that you installed yourself. You install a compact tuner box out of the way and connect it to your existing stereo with either the built-in wired FM switcher or the auxiliary stereo output. Install the dashboard somewhere convenient on your dashboard and you’re good to go.
The control panel features a large, backlit multi-line screen that displays the station information, as well as the artist and song title, with previews of the station’s multicast channel. Use 20 FM and AM presets to skip to your favorite stations with the touch of a button. If you are in an unfamiliar area just use the manual or search for the settings
Conclusion
In this paper, we assess the performance of the HDR benchmark. Technically, the HDR standard uses coherent subtractor extraction. From the simulation results, it can be seen that the performance of the system can be maintained in a drop range under different channel rates. The analysis of HDR system performance can be used in this paper as reference data for test broadcasts. It can also be used as a base material for the verification system.
To conclude, HD Radio is a modern feature which is highly developed, but specialists still updating it to make it more useful and easier to exploit, So I hope that everyone will know how to use it and how to fully benefit from it, because, if you use it perfectly, this will be great. thing
