Digital radio

Summary

Digital radio describes radio technologies which carry information as a digital signal, by means of a digital modulation method. The most common meaning is digital audio broadcasting technologies, but the topic may also cover TV broadcasting, two-way digital wireless communication technologies, and radio delivered via the Internet. The acronym DAB (Digital Audio Broadcasting) is synonymous with the Eureka 147 standard.One-way standards are those used for broadcasting, as opposed to those used for two-way communication. While digital broadcasting offers many potential benefits, its introduction has been hindered by a lack of global agreement on standards. The Eureka 147 standard (DAB) for digital radio is the most commonly used and is coordinated by the World DMB Forum, which represents more than 30 countries.
