DRM: The World’s Only open standard, Universally Standardised Digital Radio System
DRM is the world’s only open standard, digital system for long-wave, medium-wave and short-wave and the VHF bands, including the FM bands, with the ability to use existing frequencies and bandwidth across the globe.
DRM’s success in standardization and regulation with ETSI and the ITU is outlined below.
The DRM System Specification has been approved and published by the European Telecommunications Standards Institute (ETSI). The standard has evolved from the original, which covered only the AM bands, to the current version which includes operating modes for all the frequency bands below 300 MHz. In addition, ETSI has published additional specifications that allow contribution and distribution networks to be built, and allow data applications in addition to audio. DRM is also able to transmit data applications designed for the DAB system, enabling authoring tools and receiver decoders to be reused.
The DRM Consortium has worked closely with the ITU and administrations to ensure that DRM can be deployed globally. ITU-R has published bothe system recommendations and planning parameter recommendations for DRM, both for use in the AM bands and VHF bands. In addition, digital transmission is often authorised in place of analogue transmission provided that no greater amount of interference will be generated.
The most relevant ITU-R Recommendations are listed below:
