Digital Technologies And The Future Of Radio: Lessons From The Canadian Experience., Brian O'Neill
Conference Papers
This paper examines the position of digital radio in Canada. It examines the Canadian experience of digital radio development from its introduction in 1995 to the present and asks whether the approach adopted and the lessons learned provide useful models for application elsewhere. Three main strands form the background to digital radio’s current stage of development: firstly, the introduction and early support for Digital Audio Broadcasting or (DAB) in the mid 1990s; secondly, the response of the radio industry to the internet and new media as complementary to traditional radio broadcasting provision; and thirdly, the more recent experience of the …

Digital Radio Policy In Canada: Fragmentation Or Evolution Of The Medium, Brian O'Neill
Conference Papers
In December 2006, the Canadian Radio-Television and Telecommunications Commission (CRTC) issued its review of Digital Radio Policy. This replaced the transitional digital radio policy of 1995, and sought to implement a framework designed to support multi-platform digital radio broadcasting in an increasingly complex technological environment for the medium. Drawing on policy analysis, interviews and expert group perspectives, this paper traces the background to the legislative provision for digital radio development in Canada. While Canada was an early adopter of the Eureka-147 or Digital Audio Broadcasting (DAB), the policy of DAB as a replacement technology approach proved to be mistaken. Subsequent …

Digital Watermarking And Self-Authentication Using Chirp Coding, Jonathan Blackledge
Articles
This paper discusses a new approach to ‘watermarking’ digital signals using linear frequency modulated or ‘chirp’ coding. The principles underlying this approach are based on the use of a matched filter to provide a reconstruction of a chirped code that is uniquely robust, i.e. in the case of very low signal-to-noise ratios.
Chirp coding for authenticating data is generic in the sense that it can be used for a range of data types and applications (the authentication of speech and audio signals, for example). The theoretical and computational aspects of the matched filter and the properties of a chirp are …
