"This guide is aimed at the management of broadcasting organisations in areas of policy making as well as in programme making and technical planning. It explains in some detail the advantages gained by radio broadcasters introducing the DRM® Digital Radio Mondiale™ technology and some of the technical and commercial considerations they need to take into account in formulating a strategy for its introduction. The guide is a development of the previous ‘Broadcast User Guide’ and includes information on latest system and regulatory aspects for the introduction of the various DRM system variants. It also includes links to reports and articles on an extensive range of highly successful real-life trials. Digital Radio Mondiale (DRM) is the universal, openly standardised digital broadcasting system for all broadcasting frequencies up to 300 MHz, including the AM bands (LF, MF, HF) and VHF bands I, II (FM band) and III. DRM is greener, clearer, wider, bigger, better quality & audio content and cost efficient than analogue radio; it provides digital sound quality and the ease-of-use that comes from digital radio, combined with a wealth of enhanced features such as, Surround Sound, Journaline text information, Slideshow, EPG, and data services. DRM enables digital radio transmissions in the former AM bands (short, medium and long wave, i.e. broadcasting bands up to 30 MHz), providing large coverage areas and low power consumption, as well as in the VHF bands above 30 MHz up to around 300 MHz (including the FM band) for local and regional digital radio services. Irrespective of the transmission frequency, DRM uses the same audio coding, data services, multiplexing and signalling schemes; only the transmission mode parameters (i.e. modulation or baseband parameters) are optimised for the respective frequency band."
