Pulse Analysis

The Digital Radio Mondiale (DRM) consortium has just released version 6 of its DRM Handbook, an 83‑page technical guide now available in both English and Chinese. Issued alongside the DRM General Assembly in Indonesia, the handbook consolidates the latest standards, trial results, and deployment best practices for the growing global digital radio ecosystem. As more countries transition from analog AM/FM to digital platforms, a comprehensive reference like this helps broadcasters, equipment manufacturers, and regulators align on a common technical foundation, accelerating adoption across emerging markets.

The new edition expands on several key technologies. It provides richer examples of DRM multichannel transmission, enabling stations to carry multiple audio streams and data services within a single frequency. Detailed AMSS (Amplitude Modulation Signalling System) use cases illustrate how legacy analog AM can be seamlessly signaled for digital upgrades. A dedicated section on the Emergency Warning Functionality (EWF) Manager shows how national alert systems can be integrated, offering real‑time, geo‑targeted warnings to listeners. Additionally, the handbook outlines Journaline’s revenue opportunities through granular listener targeting, interactive content, and audience measurement tools.

For industry stakeholders, the handbook serves as both a technical manual and a business roadmap. Broadcasters can leverage the outlined revenue models to monetize digital services, while manufacturers gain clear specifications for receiver development, reducing time‑to‑market. Emergency management agencies benefit from the standardized EWF framework, improving public safety communications. By making the guide freely downloadable, DRM lowers barriers for smaller markets to explore digital radio, potentially expanding the global digital broadcast footprint and creating new advertising and data‑service revenue streams.
