There are two important characteristics that recommend digital radio as a service most people would like to have in their vehicles or homes: quality and content. When talking about quality we mostly refer to how clear the sound output is from digital radio when compare to terrestrial radio broadcasts. Content, on the other hand, refers to the quality of the transited material. This is where the two giants in the digital radio industry Sirius and XM Radio battle it out. The quality of the receivers and the technologies they both use are similar, but the difference can be made when it comes to exclusive high quality content. Lets have a look at both the digital radio quality and content characteristics:
The broadcast quality is, when put in numbers, of 128kb/s 44.1khz for both digital radio service providers. This is the equivalent of CD quality. Although the coverage of digital radio, which is far superior to what any terrestrial radio station can deliver, is an important factor, the quality of the sound is what brought Sirius and XM Radio more subscribers.
