What is BS EN 62272-1- Digital Radio Mondial (DRM) about?
BS EN 62272-1 is part one of an international multi-series standard that discusses the aspects of the Digital Radio Mondiale (DRM).
BS EN 62272-1 gives the specification for the Digital Radio Mondiale (DRM) system for digital transmissions in the broadcasting bands below 30 MHz.
BS EN 62272-1 gives a general presentation of the system architecture and gives reference to the subclauses defining the individual parts of the system.
Who is BS EN 62272-1- Digital Radio Mondial (DRM) for?
BS EN 62272-1 on Digital Radio Mondiale (DRM) is relevant to:
- Broadcasters
- Network providers
- Manufacturers of receiver and transmitter
- Research institutes
- Regulatory authorities
- Quality control personnel
- Product development/innovation teams
Why should you use BS EN 62272-1- Digital Radio Mondial (DRM)?
The DRM system is designed to be used at any frequency below 30 MHz, i.e., within the long-wave, medium-wave, and short-wave broadcasting bands, with variable channelization constraints and propagation conditions throughout these bands. To meet the need for a digital transmission system suitable for use in all the bands below 30 MHz, the Digital Radio Mondiale (DRM) consortium was formed in early 1998.
The DRM Consortium is a non-profit making body that seeks to develop and promote the use of the DRM system worldwide. Its members include broadcasters, network providers, receiver and transmitter manufacturers, and research institutes.
BS EN 62272-1 explains the DRM transmission super-frame, consisting of three channels i.e., the Main Service Channel (MSC), the Fast Access Channel (FAC), and the Service Description Channel (SDC). The MSC gives you the data for the services. The FAC provides you with information on the channel width and other such parameters and provides service selection information to allow for fast scanning. The SDC informs about how to decode the MSC, how to find alternative sources of the same data, and gives the attributes of the services within the multiplex.
BS EN 62272-1 describes as follows the frequency bands used for broadcasting below 30 MHz:
- Low frequency (LF) band - from 148.5 kHz to 283.5 kHz, in ITU Region 1 only
- Medium frequency (MF) band - from 526.5 kHz to 1 606.5 kHz, in ITU Regions 1 and 3 and from 525 kHz to 1705 kHz in ITU Region 2
- High frequency (HF) bands - a set of individual broadcasting bands in the frequency range 2.3 MHz to 27 MHz, available on a worldwide basis
These bands offer unique propagation capabilities that permit the achievement of:
- Large coverage areas, whose size and location may be dependent upon the time of day, the season of the year or the period in the (approximately) 11-year sunspot cycle
- Portable and mobile reception with little impairment caused by the environment surrounding the receiver
BS EN 62272-1 illustrates some solutions for transmitting the AM and DRM signals from a single transmitter that can help you to expand your business globally.
Overall, BS EN 62272-1 is useful as it provides guidance on the system specification of Digital Radio Mondial (DRM) which can be beneficial for your business.
