Video Over Shortwave Demonstrated at IBC

AMSTERDAM: Transmission of video over the shortwave radio topology is being demonstrated at IBC by Fraunhofer. The company rolled out “Diveemo,” a system delivers video via Digital Radio Mondiale, the MPEG-4-based broadcasting technology used in the AM radio band. It was demonstrated today at the convention with BBC content displayed on a NewStar DRM receiver, Fraunhofer said.

Operating at just 8 frames per second, Diveemo transmissions are not designed to compete with even standard analog television; instead, Diveemo is being positioned for large-area distribution of education and news programs where the video supplements an existing audio program.

Fraunhofer notes that shortwave transmission can reach from “100 to well over 5 million square kilometers depending on conditions and broadcast parameters. The service opens the door to a large range of unprecedented information and education services and is an ideal platform to reach audiences worldwide with a single DRM transmitter or an even more cost-efficient DRM single frequency network. Diveemo offers free-of-charge reception and is independent of gatekeeper and third-party providers like satellite and cable networks.”

The system is being demonstrated by Fraunhofer and Thomson Broadcast on their respective stands at IBC2010. Fraunhofer and Thomson, along with Chengdu NewStar Electronics, developed Diveemo. The service is being presented for standardization by ETSI, and can be implemented by any broadcaster using DRM30 or DRM+.

Video files are added to the Fraunhofer DRM ContentServer where they are converted to MPEG-4 and prepared for transmission. DRM+ is capable of devoting a larger amount of data to the video than DRM30, allowing for better video quality with DRM+. Diveemo complements existing data services within DRM30 and DRM+, including MOT Slideshow for still images and Journaline for text-based data services.– With Radio World

India To Go DRM

In the broadcasting world, All India Radio has been an early adopter of DRM technology. I was pleased to find this article from the DRM Consortium via Andy Sennitt at RNW Media Network:

The Digital Radio Mondiale (DRM) Consortium has welcomed the Indian government‘s approval of All India Radio (AIR)’s ambitious plan of converting its vast broadcasting network to digital using the DRM standard. India is one of the first countries in the world to implement such an extensive and well-researched plan to upgrade its radio infrastructure using the global open DRM radio technology and thereby ensuring that it can maintain significant reach to its 1.2 billion strong population whilst delivering enhanced radio services.

India’s Cabinet Committee on Infrastructure on Thursday 8 April gave its approval to the proposal from the Ministry of Information and Broadcasting regarding 11th Plan of Digitalisation where Rs 9.20 billion (approx US$200 million) have been earmarked for AIR to convert to digital which will cover approx 70 per cent of the country. By converting to digital, AIR will deliver enhanced radio services that offer crystal clear sound, increase user experience with additional functionality such as automatic tuning by station name, interactive user interface through digital screens that offer slide-shows and many other services like EPG, Journaline.

The digitisation scheme involves the installation of over 40 digital (DRM capable) transmitters as well as other digital enhancements and networks for both state radio and television.

All India Radio (AIR) began moving towards digitisation with the adoption of the DRM standard after extensive field trials and tests since 2007 that was offering in their opinion the most ‘robust, reliable’ technology. Last year, it started a regular DRM broadcast from one of its high-power shortwave transmitters located at Khampur near Delhi and this year it acquired two high powered mediumwave DRM transmitters.

The Di-Wave 100, a new DRM digital radio receiver was unveiled at the annual general assembly of the DRM Consortium in Erlangen, Germany. This is big news indeed for DRM enthusiasts as there are so few versatile stand-alone DRM receivers in production.

This announcement also coincides with other exciting news in the DRM world, namely that India and Russia are backing the digital mode for future broadcasts.  See press release here.

The Di-Wave 100 has a USB/SD card  reader and mp3/mp4 play-back. It sports a 3.5 inch TFT color display that reveals station identification, program information, Journaline, MOT Slideshow and listening time shift in several languages. The Di-Wave 100 can receive DRM broadcasts in SW, MW and LW as well as analogue FM and can store 768 stations in its memory.

It should be noted that the Di-Wave 100 will be the first consumer DRM receiver authorized by the FCC for sale in the United States. When FCC approval is granted, the Di-Wave 100 (a.k.a. UniWave Di-Wave) can be purchased from Universal Radio.

UPDATE: Universal Radio is now selling the Di-Wave in North America for $299.95 US. The Di-Wave is also available for sale in Thiecom’s online catalog in Germany (249€) and in AV-COMM’s online catalog in Australia ($499AU). Two other distributors in Germany are Charly Hardt and Alan Electronics.
