The Digital Radio Mondiale (DRM) broadcasting system has been designed by broadcasters, for broadcasters, with the active assistance and participation of both transmitter and receiver manufacturers and other interested parties (such as regulatory bodies).
DRM is an open standard, meaning that its system description is openly published allowing all manufacturers and interested parties to have free access to the complete technical specifications and can design and manufacture equipment on an equitable basis. This has proved to be an important mechanism for ensuring the timely introduction of new systems to the market and for accelerating the rate at which equipment prices reduce. This is a significant consideration for broadcasters investing in DRM infrastructure, manufacturers investing in receiver development and production, and even more for the listeners who will need to invest in the new DRM-capable receivers.
DRM is the only global digital radio standard that embraces all the currently used radio frequency bands. It has been designed specifically as a high-quality digital replacement for former analogue radio broadcasting in the AM and FM/VHF bands; as such it can be operated with the same channelling and spectrum allocations as currently employed. An overview of the frequency-bands where DRM operates is shown in the Figure below:
For the physical transmission, the DRM standard describes several different operating modes (i.e. modulation parameter sets), which may be broadly split into two groups:
For DRM transmissions below 30 MHz there are four different robustness modes which allow the DRM signal to be tailored for the AM broadcast bands with their very diverse propagation characteristics enabling regional up to international service coverage
A dedicated robustness mode, which is centred above 30 MHz on the FM broadcast band and optimized for transmissions in the VHF bands, can be used for local to regional service coverage.
DRM has received the necessary recommendations from the ITU, hence providing the international regulatory support for transmissions to take place. The main DRM standard has been published by ETSI. In addition, ETSI publishes and is the repository of the entire range of current DRM technical standards.
The introduction of DRM services allows a broadcaster to provide listeners with significant improvements in service reliability, audio quality and, most importantly, usability. The standard provides many features and facilities that are impossible to replicate in analogue broadcasting. It is essential that prospective broadcasters understand the potential and flexibility of the system to allow them to optimise and configure their DRM networks in accordance with their own market conditions.
