DIGITAL RADIO GUIDE INTRODUCTION

1 Introduction

Digital technology has steadily transformed the way in which programmes are made and

distributed in recent years. Already many broadcasters have invested in digital systems

for contribution and production and now the switch from analogue to digital is moving

along the broadcasting chain into transmission. At the same time, digital developments

are drawing together the broadcasting, telecommunications and computer industries in a

process of convergence. For all broadcasters, this is leading to a new and challenging

business environment in which they are searching for a clear ‘multimedia’ role.

Although similar changes are happening in both radio and television, this guide deals with

radio. It is designed to help managers, including those in developing countries, identify

the technical and business forces that are driving the analogue to digital conversion

process. There are many benefits that radio broadcasters stand to gain by adopting

digital technology and the current interest in digital television should help and encourage

the switch from analogue to digital in radio broadcasting. The issue is likely to be brought

into sharper focus if and when individual countries or regional groups set timetables for

phasing out existing analogue services.

This updated Digital Radio Guide focuses primarily on the various digital radio systems in

operation today and their associated standards. The guide visits not only terrestrially

based digital system but also overviews the services now available via satellite radio.

The important development seen in this updated guide is the significant changes to

digital radio development compared to the original guide published in 1998. The first

guide presented many options for the US-based studies into digital radio as well as

satellite radio. These systems have now matured to the level that there is unlikely to be

changes in the choice for digital standards for many years. The only development

planned at present is that by the DRM Consortium with its DRM120 project.

This guide is a compilation of inputs provided by WBU members for the benefit of the

world broadcasting community. Note that references to relevant worldwide websites and

a glossary of acronyms are provided in Appendices B and C at the end of this guide.
