The Asia-Pacific is the world's largest region and it has a huge range of potential radio uses that analogue terrestrial broadcasting simply cannot meet. This article explores the impact that digital radio transmission will have on the region, and the importance of satellite broadcasting and multichannel broadcasting for better coverage and quality of services.

Abstract: This article presents an overview of digital radio policy in Canada in the period 1995 to 2005 and the attempt to implement the Eureka-147 Digital Audio Broadcasting (DAB) standard as the replacement technology for analog AM and FM broadcasting. Canada was an early adopter of this system, but unfavourable conditions have led it to largely abandon the approach in favour of a multiplatform system. The interaction between industry, government regulation, and broadcasting policy around digital radio reveals a complex situation of competing interests. Despite extensive regulatory intervention to protect Canadian interests, the pace of technological change and the dominant influence of U.S. interests have made the transitional path to digital radio even more uncertain than it was 10 years ago. Résumé : Cet article offre un survol des politiques qui régissent la radio numérique au Canada pour la période de 1995 à 2005 et expose la tentative d'implantation de la norme Eureka-147 Digital Audio Broadcasting (DAB) comme technologie de remplacement pour la diffusion analogue AM et FM. Le Canada fût rapide à adopter ce système, mais des conditions défavorables l'on mené à l'abandonner en très grande partie en faveur d'un système multi plateforme. L'interaction entre l'industrie, la réglementation gouvernementale et la politique de diffusion qui touchent à la radio numérique révèle une réalité complexe composée d'intérêts concurrents. Malgré une vaste intervention en matière de réglementation visant à protéger les intérêts canadiens, le rythme des changements technologiques et l'influence dominante des intérêts américains ont rendu le passage transitoire à la radio numérique encore plus incertain qu'il ne l'était il y a 10 ans.

Purpose – The diffusion of digital radio has experienced more challenges than for digital TV regarding a digital switchover. The purpose of this paper shows on the specific case of Germany, which difficulties the digital sound broadcasting technology of Digital Audio Broadcasting (DAB) has been facing from several points of view. The difficulties are reviewed and outlined to overcoming different barriers and to facilitating its diffusion. Design/methodology/approach – The paper analyses how the diffusion of digital radio is perceived by industry representatives such as radio consultants and several stakeholders along the value chain of the radio industry. In semi-structured interviews, participants describe and evaluate the challenges for DAB as digital audio broadcasting standard mainly in Germany. Findings – After two decades of deploying digital radio in Germany, its success is still missing. Various very different aspects have prevented the diffusion of the new technology. Among various barriers, the radio industry sees missing benefits, marketing errors and a lack of inter-industrial collaboration as barriers in a retro-perspective. Research limitations/implications – The analysis does not cover other countries, where DAB as standard was introduced. Also other standards for digital radio are not considered. Practical implications – With referring to barriers for digital radio, there is a scope for those countries about to introduce the technology to troubleshoot the failings of overcoming barrier. An idea can emerge, how authorities and industrial stakeholders can help to facilitate the diffusion of digital radio. It also indicates the need of governmental interaction for the coordination of a technology introduction in a network industry. Social implications – The theoretical model, referred to, gives a good overview of potential diffusion barriers as most identified problems for the German case. The model and the illustrated problems of the paper can be used in practice to manage potential diffusion problems during technology introductions. Originality/value – There is a lack of published information about the faced challenges for the diffusion of digital radio. The retro-perspective benefits from the broad experience of participants having observed the challenges of the past decade with DAB in Germany. Additionally, the results are mapped to a theoretical framework with limits for the diffusion of innovation for generalising.
