DRM is the complete digital radio solution
DRM is the complete, open and internationally recognised solution for digitising radio in all frequency bands. It uses less spectrum, which can be released for other use. Through DRM listeners can tune in on station name not frequency, can get multimedia content, audio and text information, as well as pictures. Radio receivers can automatically switch for emergency warnings in case of impending disasters. DRM ensures genuine green broadcasting through less power usage and therefore less costs.
Benefits for Regulators
An international standard
Digital Radio (DRM) is the universal, openly standardised digital broadcasting system for all broadcasting frequencies below and above 30 MHz, including LW, MW, SW, band I, II (FM band) and band III. DRM has been successfully tested globally while larger countries such as India have already adopted DRM as their digital radio standard.
DRM can be deployed on its own or as a complementary technology to plan a successful and flexible transition to digital radio.
Uses less spectrum and releases spectrum for other use
DRM is able to achieve real benefits in spectrum efficiency in all circumstances. This is through tailoring spectrum use to actual broadcast requirements.
In the VHF band, DRM can be configured to use less spectrum than current stereo FM broadcasts (half of it, actually), whilst additionally deriving the potential benefits of increased robustness, reduced transmission power, increased coverage and additional services.
DRM in AM bands can replace AM transmissions on the Short, Medium and Long wave bands. In this case there are no spectrum savings but the perceived quality on digital AM would be closer to that of FM broadcasting, thus making better use of the available spectrum. Equivalent coverage can be maintained with a significant power reduction.
Lower power costs – green broadcasting
DRM programmes on Short, Medium and Long wave for broadcasting bands up to 30MHz (‘DRM in AM’) cover large geographical areas with much lower power consumption.
DRM in the VHF bands (above 30 MHz) uses the existent infrastructure and maintains the coverage area at slightly reduced energy costs but with more content capacity.
Emergency warning alerts
Due to the unique feature of DRM as an all-frequency-bands standard, the Emergency Warning in-built feature is suitable for governments of large countries, where disasters may occur frequently. The DRM system sends an alert signal to receivers that in turn switch automatically to emergency channels. DRM enables the delivery of emergency and alert programmes containing both audio and text in several languages simultaneously. This provides essential and real time information and advice to the population, thus fulfilling one of the major roles of governments across the world.
DRM is the only digital radio system that triggers automatic switch to the emergency warning channel, even when the receiver is in stand-by.
