HD radio is an exciting new technology that enables AM and FM radio stations to broadcast their programs digitally. These digital broadcasts provide listeners with the highest quality of audio. With digital radio, you will never again be disturbed by signal fading, static, hisses, or pops. Additionally, HD radio gives FM broadcasts CD-quality sound. AM broadcasts can sound almost as good as today's analog FM stereo. HD radio features various new forms of data services. Text on a radio screen can display information regarding song titles, artist names, traffic updates, and weather forecasts. Not only will radio stations be able to duplicate their analog programming with an HD radio broadcast, they can also subdivide the digital portion of their signal, allowing them to "multicast," which means that they can broadcast two or more programs simultaneously. Multiple signals give listeners a choice--you could choose, for example, between a sports game or music. A multitude of other services are available, such as surround sound, multiple audio on-demand audio services, and store-and-replay. Store-and-replay allows you to store a radio program while you are away, and replay it when you get home. HD radio also features a "buy" button for music, concerts, and sporting events. Here's the best part--HD radio is free for consumers. Just like regular radio, there are no subscription fees. Hundreds of radio stations throughout the country are have now licensed hi def HD radio technology. There are currently a number of HD ready radio products on the market. The next year will likely be an exciting time for audiophiles. |
