Digital Audio Broadcasting in Canada: Technology and Policy in the Transition to Digital Radio
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
