DAB stands for Digital Audio Broadcasting

Digital Radio is the name chosen by the marketing to launch the broadcast of the transmissions made with the Eureka 147 standard, better known as Dab + . The Dab (Digital Audio Broadcasting) is actually quite mature stuff: it’s a European project that dates back to the eighties. Nearly 20 years ago, in 1995, Norway and the United Kingdom activated the first DAB digital radio channels. In 2007 the evolution was born, the Dab +. And it is with this standard that broadcasters today also broadcast in Italy. To receive a digital program you need to equip yourself with a special receiver, either home or car.

The development of audio compression codings: the DAB + is born

Take advantage of the efficiency and performance of MPEG-4 (AAC) with the result of having the same audio quality at a lower bitrates.
Another major innovation was the addition of video / multimedia capabilities for Digital Audio Broadcasting, allowing DAB to become a digital DMB (Digital Multimedia Broadcasting) mobile TV platform as well as a digital multimedia radio platform.
DMB and DAB + are extensions of the DAB technical base.

More than half a billion people around the world today are able to receive over 1,000 radio stations and DAB data services. Most of these contents have gone from the experimental to the regulated phase, and the use of the Eureka 147 standard has been confirmed throughout Europe, the Far East and Australia.

Radio is changing, not being left behind, going digital

It is a digital broadcasting system. DAB is the transmission technology designed to integrate the analog FM radio band in the medium term.
The DAB system was developed in Europe as part of the EUREKA 147 project and is currently operational in many countries. The DAB family of standards includes DAB and DAB + for digital radio and DMB for mobile TV. They are global and open standards, the perfect medium for transmitting terrestrial digital radio signals.

At its birth in the late 1980s, the original DAB (Digital Audio Broadcasting) was based on MPEG Audio Layer II, which was also the object of investment and experimentation for EuroDab Italy, today it is still commonly used in some European countries. due to a large number of receivers on the market.
