Demo on DRM Transmissions at Bangalore :

Digital Radio Mondiale (DRM) is a new terrestrial digital sound broadcasting technology in MW and SW bands. DRM can provide wide coverage - the inherent advantage of long distance propagation characteristics of this band. Due to robust digital modulation and coding schemes employed, DRM can provide FM like sound quality to the listeners. It also has additional advantage of carrying data transmission along with the audio, easy selection of the frequency for the user etc.

World wide, DRM transmission by majority of the public service broadcasters like BBC, Deutsche Welle etc has already started. Recently, AIR too has inaugurated DRM transmission from Delhi. Expert opine that, in coming years, gradually, DRM shall replace the conventional analog sound broadcasting in MW and SW bands.

Considering the importance of DRM technology in terrestrial sound broadcasting, Bangalore chapter of Broadcast Engineering Society, has arranged a presentation/ demonstration of this technology by me on 23rd March 2009 at 1800 Hrs at BEL officers club, BEL, Jalahalli, Bangalore. Presentation will contain brief like necessity, objective, system summary, broadcast hardware infrastructure, service planning of DRM technology etc. Also, demonstration of field recorded sound of the DRM will be made.
