Digital Radio Mondiale: features and requirements from a broadcaster's perspective
The year 2003 sees the official launch of Digital Radio Mondiale (DRM), the new broadcast system for short-wave, medium-wave and long-wave. As with many digital broadcasting systems that replace their analogue predecessor, DRM offers a long list of enhancements and new features that broadcasters should be aware of. The paper presents DRM from the perspective of broadcasters who are considering introducing DRM services or switching their analogue transmissions to digital technology. What is the trade-off between audio quality and signal robustness? What is the impact on the production of radio programmes in the studio? What issues need to be considered on the transmitter side? What features are available to increase the radio listening experience? These and other questions will be considered in this paper.
