ABSTRACT

The first system that was developed was the European Eureka-147 or Digital Audio Broadcasting (DAB) system. The term DAB is used as a general term for digital audio broadcasting and it is also used as a synonym for Eureka-147. This chapter provides a brief technical description of many of the systems mentioned in the introduction. It focuses on audio services in the case of DMB and DAB+, there is also video broadcasting. The chapter describes two potential future upgrades of the HIBOC-FM system. It presents an improved receiver based on the concept of the List Viterbi Algorithm. The second potential system improvement is related to simultaneous transmission of the host analog frequency modulation and digital. With the advent of the compact disc (CD) and higher-quality distribution channels for music, the need for radio broadcasting of digital audio with CD or CD-like quality arose. For successful digital audio broadcasting, efficient high-quality audio compression was required.
