DRM - One of the highlights of the International BES Expo 2020


Digital Radio Mondiale™ (DRM) – One of the Highlights of the International BES Conference and Exhibition in New Delhi

The DRM Consortium highlighted its recent achievements under the overarching theme "DRM for India - Smart Radio for ALL" at the 26th edition of the international BES (Broadcast Engineering Society – www.besindia.co.in) conference and exhibition (BES EXPO 2020) on Broadcast & Media Technology, in Halls 7ABC&E, at Pragati Maidan, New Delhi, India, 13-15 February 2020.  

The not-for-profit DRM Consortium (www.drm.org) and some of its Indian and international members and partners (including Fraunhofer IIS, Gospell Digital Technologies, Inntot Technologies, NXP, RFmondial, Starwaves, Dolby etc.) welcomed all visitors at Hall 7A – Booths 61 and 49, a larger and more visible presence than ever before. Visitors could see and experience live AIR broadcasts in pure DRM on the variety of receivers on display. They ranged from very low-cost "tuk-tuk" type receivers to full-feature DRM sets complemented by automotive solutions able to receive locally generated DRM in the FM band with live emergency warning functionality.

The efficiency of DRM digital FM broadcasts was highlighted through a demo that showcased the combination of up to 6 independent DRM signals onto a single FM transmitter – providing 12 to 18 audio services plus multimedia content with shared infrastructure cost. The DRM Digital FM solution for the Indian FM broadcasters is fully compatible with both the existing analogue FM services as well as with AIR's existing DRM AM-band transmissions in India.

Visitors could also experience a public display signage demonstration that gives information based on a live DRM Journaline advanced text service. During times of emergency, the public screen becomes a public alert station with full volume audio and visual emergency information.

Another innovation was the online monitoring of the live DRM content of selected transmitters from all over India, allowing both technical and editorial staff to monitor DRM in real time.

For the first time at BES, Nautel, one of the key Consortium members, hosted a DRM event giving an update on DRM latest developments and improvements. This was the ideal opportunity to announce the winner of the DRM Enterprise Award 2019, the Southern Indian company Inntot Technologies, developer of Indian solutions for the automotive and standalone receivers.

The BES conference underlined some of the new things shown in the exhibition hall. They focused on the increased opportunities for enhancing the radio business with DRM, as well as very efficient ways of sharing the DRM transmitter infrastructure. On the last day of the conference DRM led a panel discussion where representatives of AIR and the receiver industry debated the key requirements of a successful and complete DRM rollout in India.

According to Ruxandra Obreja, DRM Chairman, "India has made tremendous progress on the road to radio digitisation. A public launch date is now necessary to bring the benefits of DRM in all bands to the whole Indian population on receivers in cars and in standalone receivers at prices that are affordable to increasing numbers of listeners.

DRM allows for multiple FM-like radio services plus associated data such as multi-lingual news articles to be carried in place of or as an extension to the former analogue radio services, while maintaining the large-area service coverage of the AM bands.

35 MW transmitters of AIR, of power ranging from 20 kW to 1000 kW, continue to operate in DRM – 2 of these in pure DRM and 33 in simulcast. 25 of these are working in pure DRM daily for one hour. 2 SW transmitters are also carrying services on DRM.Two more transmitters, 100 kW each, are under trial in Delhi and these are expected to be operational soon.

Digital Radio Mondiale endorses & exhibits at international BES conference & exhibition in New Delhi

The DRM Consortium will highlight its recent achievements under the overarching theme "DRM Drives Forward" at the international BES (Broadcast Engineering Society –  www.besindia.co.in) conference and exhibition BES EXPO 2019 on terrestrial and satellite broadcasting at Pragati Maidan, New Delhi 110002, India, 17-19 January 2019.  BES EXPO is rated as the biggest broadcast technology show in India with nearly 300 exhibitors from 25 countries and an estimated 3,000 professionals and decision-makers attending.

The DRM Consortium (www.drm.org) and some of its Indian and international members and partners (including BBC, Communication Systems Inc., Fraunhofer IIS, Gospell Digital Technologies, GeekSynergy, Inntot Technologies, NXP, RFmondial), will welcome all visitors at booths 72 and 73 (in Hall 7B), ready to present the latest DRM receiver models and solutions as well as letting visitors experience a live DRM transmission for local coverage.  Visitors will be able to learn more about the latest DRM encoder equipment with full CAP compliance able to support the roll out of DRM Emergency Warning Functionality in India.

A three-day conference on the theme "Next Generation Broadcasting in the IT World" will be held in parallel with the exhibition and will include three DRM sessions. One of these will be a panel discussion on the successes and next steps necessary for getting receivers to the population in parallel with the introduction of DRM transmissions in the country.

According to Ruxandra Obreja, DRM Consortium Chairman: "As the DRM All India Radio roll-out makes India potentially the largest digital radio market in the world, the DRM Consortium is keen to showcase the many benefits of DRM emphasising its local coverage potential. Digital radio DRM is already showing its superiority, as its features and benefits overtake anything the analogue mode can provide. Using the full DRM standard in both AM and FM is the only way to make it attractive to the Indian listeners, to the whole country engaged on the digital path."
