Abstract

For some time, Internet radio is a fact.

Internet via radio is the ability opened by the digital multimedia radio DAB (Digital Audio Broadcasting) and its newer version DAB+.

This is a new perspective of a radio. A radio enriched – beyond traditional programs of audio and music – by the resources of added information. DAB is a multimedia radio allowing transmission of audio, text, graphics, photographs, maps, charts, and video.

The position of the modern radio in the digital communication world is due to its basic features:

• Digital transmission techniques

• Unilateral simultaneous transmission (broadcasting) for large social groups

• Capabilities of multimedia transport

Digitalization of radio – a necessary condition for the transmission of multimedia data – required new concepts and techniques developed in the framework of the EU Project Eureka 147 DAB and further improved within radio institutions under the WorldDAB organization.
