This meant having the ability for the transmissions to occupy a variety of different bandwidths dependent up the location and frequencies in use. The main thrust of the development was to ensure that far greater audio quality could be achieved, but this needed to be achieved whilst keeping the transmissions in a form where they could operate alongside the existing AM transmissions. When the specification for DRM, Digital Radio Mondiale was being drawn up there were a number of key requirements that needed to meet. A preliminary system was designed and tested within a laboratory and this was later extended to include field trials on air to ensure that the new system would successfully meet all the requirements.

As a result the new system has come to fruition remarkably swiftly. It has been able to draw on the experience of the membership to ensure that the resulting standard met the requirements, and it has also drawn on the experience gained by the Eureka project that was set up to develop DAB Digital Radio. Now with 82 members, the wide base of its membership has been part of the reason for its success. It was founded in Guangzhou, China in 1998 and now has its headquarters in Geneva. What is DRM?ĭRM itself is a consortium of broadcasters, network operators, equipment manufacturers, broadcasting unions, regulatory bodies and other organisations representing 29 countries.

Known as DRM it provides many of the improvements that are badly needed along with the flexibility to allow for future developments. As the requirements are very different to those experienced on the higher frequencies the DAB standard is not applicable and as a result a totally new system has been developed. The next stage is to improve the transmissions on the long medium and short wave bands. Now DAB Digital Radio is available in many countries and this has set new standards in broadcasting. Broadcasts in the VHF FM band have received far more listeners with the result that audience figures are dropping for AM broadcasting. These transmissions are of low audio quality and particularly in recent years there has been a move away from these bands to find higher quality transmissions. Since the very earliest days of broadcasting these wavebands have been filled with signals that are amplitude modulated.
