Wikipedia About Digital Radio

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 as well as many two-way digital wireless communication technologies. The acronym DAB (Digital Audio Broadcasting) is synonymous with the Eureka 147 standard.

One-way digital radio standards

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. This standard of digital radio technology was defined in the late 1980s, and is now being introduced in many countries. Commercial DAB receivers began to be sold in 1999 and, by 2006, 500 million people were in the coverage area of DAB broadcasts, although by this time sales had only taken off in the UK and Denmark. In 2006 there are approximately 1,000 DAB stations in operation. There have been criticisms of the Eureka 147 standard and so a new 'DAB+' standard has been proposed.

To date the following standards have been defined for one-way digital radio:
