Digital Radio Mondiale Transmissions during ABU and CBU Conferences

Digital Radio Mondiale (DRM) to be demonstrated simultaneously from two continents

This year's annual General Assembly of the Asia-Pacific Broadcasting Union will be hosted by the Indonesian public broadcaster, RRI, in Bali. DRM will feature not only in the meetings of the specialised committees but also concretely with a live medium wave transmission on 20-24 October from one of the RRI MW transmitter in Denpasar, Bali on 1206 KHz. The DRM broadcasts will feature special messages for the ABU participants, presentations on RRI, DRM the emergency warning functionality, music, as well as the Journaline service accompanying the audio, allowing listeners to look-up the latest news on demand, free-to-air, on their receiver screens and in multiple languages simultaneously. The DRM demo run by RRI is actively supported by GatesAir, Transradio, Fraunhofer IIs and RFmondial key members of the Consortium.

In parallel, Babcock International (member of the DRM Consortium) will transmit BBC World Service content in DRM short wave from Singapore on 11995 kHz (25 metre band) at 0500-0700 UTC or 1300-1500 local time.

After last year's DRM medium wave trial, north of Jakarta, this is another chance to enjoy the audio qualities of DRM, and, as Mr Frederik Ndolu, member of the RRI Supervisory Board said:" to show RRI's commitment in understanding what is the most efficient solution for getting the best programmes, in the best quality to all our listeners, wherever they are in our vast country."

Almost at the same time with the big gathering on the tropical island of Bali, the General Assembly of the Caribbean Broadcasting Union (24-27 October) will convene in Havana, Cuba. It will mark a significant moment as the Digital Radio Mondiale Consortium has announced it will be bringing the first live digital radio signal transmission to Cuba, the Caribbean region and parts of northern Latin America, and even as far north as Florida. The broadcast facilitated by Babcock International will come from the BBC via its Atlantic Relay station.

The DRM transmission will be in the 13 meter-band on 21720 kHz and will carry BBC World Service programmes in English. Additional multimedia features of DRM will also be demonstrated on radio receiver screens. The DRM broadcast will be on air from 1600-1800 UTC, 1200-1400 local time on Oct. 24 and 25.

Ruxandra Obreja, DRM Chairman, feels that: "this is a great opportunity to introduce DRM to the Caribbean nations, to highlight some of its great benefits, like the emergency warning functionality, so much at the top of the agenda for the people in this region of the world."

Via Announces Patent Pool License for MPEG xHE-AAC to Support Digital Radio and Mobile Streaming Applications

SAN FRANCISCO--(BUSINESS WIRE)--Via Licensing Corporation announced the availability of a patent pool license for MPEG Extended High-Efficiency Advanced Audio Coding (xHE-AAC), the latest upgrade to the AAC family of audio compression technologies used around the world for broadcast, streaming, downloading, and audio/visual capture and playback applications. xHE-AAC provides exceptional audio quality using low bit rates to deliver a listening experience suitable for mobile devices, but which can scale-up to offer audiophile-quality reproduction.

xHE-AAC is also designed to support the delivery of mixed music and speech content on mobile devices and automotive products. Applications for MPEG xHE-AAC include digital radio broadcasting, streaming over mobile networks, and audio books. Because MPEG xHE-AAC delivers bit rates as low as 12 kilobits per second (kbps) for stereo and 6 kbps for mono, it can save bandwidth and transfer costs for content distribution over the internet or wireless networks. For consumers, it can provide a more enjoyable and cost-effective listening experience on mobile devices. xHE-AAC has already been adopted for the Digital Radio Mondiale ("DRM") broadcast standard and is currently in use on DRM transmissions around the world.

"MPEG xHE-AAC is an important new technology and a significant addition to the AAC licensing program," said Andrew Fischer, Sr. Director, Audio Programs, at Via Licensing Corporation. "With xHE-AAC, the range of applications that can be enhanced by the AAC family of codecs continues to expand."

Licensors contributing research, capital investment, inventions, and development toward the standardization of this important technology include Dolby Laboratories, Electronics and Telecommunications Research Institute (ETRI), Fraunhofer IIS, Koninklijke Philips N.V., NTT DOCOMO, Orange S.A., Panasonic Corporation, Sony Corporation, and VoiceAge Corporation. Via's licensors have made their patented inventions available to the industry through Via's pool on fair, reasonable, and nondiscriminatory (FRAND) terms.

xHE-AAC is a superset of the technologies licensed under the broadly adopted AAC patent licensing program. Companies that are licensees under an existing AAC Patent License Agreement and that wish to receive a license for xHE-AAC will be able to do so through a simple addendum to their in-place patent license agreement. Similarly, reporting a mix of AAC and xHE-AAC products is streamlined for the convenience of licensees. More information, including the xHE-AAC fee schedule is presented athttp://via-corp.com/licensing/xHE-AAC/overview.html

Via Licensing Corporation is a wholly owned subsidiary of Dolby Laboratories, Inc., a company with more than 50 years of experience in innovation and technology licensing.

IIT-Kanpur alumnus does with radio what Marconi couldn't

CHENNAI/KANPUR: For his PhD at Stanford, 28-year-old electrical engineer Dinesh Bharadia decided he was not going to choose a problem that was "trivial". So he settled in on something that had stumped scientists for 150 years - how to turn radio communication two-way.

Women hams ride the radio wave in India

They are doing it all, from opening communication lines in tsunami-hit Andamans to encouraging more 'young ladies' to take to amateur radio.

Amateur radio operators, known colloquially as hams, are hobbyists who use radio waves to communicate wirelessly through Morse code, voice or even images with people around the world. Even as modern forms of communication such as mobile phones and the internet have edged out the radio, the tightly-knit global community of ham operators continues to thrive.

Digital Radio Mondiale (DRM) Key Stakeholders Make More Exciting Announcements at IBC 2016

On day two of IBC, the leading global trade show for broadcasters and media professionals from over 160 countries worldwide, Digital Radio Mondiale members introduced new transmitter deployments and receiver developments.

The first DRM event on Saturday (10th September) was hosted by Thomson Broadcast who emphasised the return on investment and cost-effective nature of investing in DRM transmitters.  Key representatives of RRI, the public broadcaster in Indonesia, and WECODEC, a non-profit organisation serving disadvantaged communities in South Africa, enriched the event with their understanding of DRM benefits for their own countries.

In the afternoon, Nautel hosted their now traditional Saturday afternoon DRM event.  Among the highlights this year was the announcement that in Europe, Antenna Hungaria (the national network operator in Hungary), have recently placed an order for a 2 megawatt DRM MW transmitter.  The Nautel representative in India also announced that All India Radio had demonstrated further confidence in the company and ordered another six DRM capable transmitters to supplement the existing thirty-five DRM transmitters currently delivering the largest digital radio project in the world.

The participants at both events had the opportunity to see and listen to receivers and software solutions demonstrated at IBC by Gospell, PantronX (Titus II), Avion, Radio Haugaland and Fraunhofer IIS.

There will be one more opportunity for delegates to win an Avion DRM digital radio at DRM's final event hosted by Ampegon and Transradio, (Hall 8 D35) on "Digital Shortwave Transmission" on Sunday 11th September 1400 to 1500.  It will be supported by Babcock International's live BBC DRM transmission on 7240 kHz, 15.30-1630 (CET) 13.30 – 14.30 (GMT).

Secure High Speed Digital Communication: The Future of Shortwave Broadcasting?

Since shortwave frequency transmissions interact with the ionosphere, broadcasts propagate many thousands of kilometres over the horizon without any intermediate delay. Using new digital technology and 64-QAM transmission, rapid digital encoding allows significantly greater data rates than possible with lower frequency transmissions.
