What Is Digital Radio Broadcasting?

Digital radio broadcasting is the broadcasting and receiving communication service through a digital technology group.

Digital technology can be used for the transmission of digital bitstreams for sound broadcasting, as well as a range of other multimedia services. This is the fundamental difference between analog and digital broadcasting. Digital broadcasting offers the flexibility of additional services (which can include text and images) to enhance the viewer experience.

Digital broadcasting only requires a radio spectrum of 1.536 MHz and provides at least 18 high quality music radio services. Analog FM radios require 1.6 MHz to provide eight services. Digital radio broadcasting is more efficient than analog FM broadcasting.

Digital radios are also less sensitive if there is adjacent channel interference. And it can use a single frequency network (SFN). This also helps in the efficient use of the radio spectrum.
