• Digital Radio Mondiale (DRM) is the only global open digital radio system which can be used

in all frequency bands (AM and VHF).

• DRM system can be used to cover large geographic

areas as well as rural and local markets and when on the

move. A low power local service option is also available.

• DRM receivers are simple and easy to use with better

audio quality and Multimedia applications.

• It is a system that complements and works seamlessly

with other digital standards.

Overview of Recent Shortwave Projects DRM equiped

• 3 x 250 kW SW near Abujia, Nigeria, including one rotatable antenna 4/4/1.0, commissioned 2012

• One 100 kW SW TX near Tashkent, Uzbekistan, commissioned 2012.

• One x 250 kW SW near Dhaka, Bangladesh, including one rotatable antenna 2/2/0.5, commissioned 2012

• 4 x 250 kW SW TX for Japan, The first one will be commissioned Mid 2013.

• 5 x 300 kW SWTX and 5 rigid dipole Antennas are under installation in Taiwan.

• Several SW Transmitters for KBS Korea are under installation.

• Libya: SW Station DRM equipped, • Sudan : MW Station DRM equipped • Interest in Southern Africa: First SW DRM transmission in October 2011 of EU live radio debate from Ascension Island to Western Africa (to and from Brazil) – feedback from Angola and S. Africa (also from Brazil!). • DRM Consortium has contributed to S. Africa government consultation • Mozambique : seems to have opted for DRM in its digitisation plans • Nigeria : new transmitter site in Abuja ( March 2012 inaugurated) , dayly DRM test transmission

DRM Projects in planning stage: RSA : Ghana: Project delayed Lesotho: Trial Summer 2013 Angola: DRM with FM re-broadcasting Kenya: Project delayed Botswana: showed interest inTrial Tanzania: Project delayed Namibia: showed interest to revamp SW Station

How ready is Africa

Government Interest for Implementation • Government interest to reach out entire country including rural areas

• extend Broadcasting Services to International coverage

• being independent from any Satellite gatekeeper

• Using DRM Transmission for education purposes

• Improving Audio quality to listeners

• Quick and fast Data Broadcasting for emergency warnings in Text, Picture and Journaline

• cost efficient transmission by using latest proof of technology

• easy change from analogue to digital mode

• using DRM as carrier for FM re-broadcasting Networks , especially in rural areas

• No need to apply new frequencies, old Licensees can be used

Key Actions for Implementation:

• Government to provide masterplan for digital radio Implementation

• Providing Funds for national Projects

• Government to subsidies digital Receiver and its marketing

• call attention the masses in offering additional services

• Get private Industry interested in producing DRM Receiver (Chipset available)

Continued use of existing transmission systems

Continued use of existing frequency planning

Reduced operating costs (energy savings) per transmission

Opportunities for added-value services with data, text and other services

Increased audience interest, resulting from audio quality improvement and

additional services

Increased advertising interest, resulting from increased audience

Independent editorial control

Control of coverage area

Rapid and short-term flexibility when required (e.g. power, transmission

time, target area, ....)



Broadcaster Interest for Implementation:

• DRM has shown new receivers (IBC, Asia, Brazil)

• Big chipset manufacturers joined DRM: FS, KeyStone,

Dibcom/Parrot – one all standards solution

• Receiver’s manufacturer’s joining: JVC Kenwood

• Handheld (NewStar), Mobile (Intel, Nokia), Car (Visteon, Delphi)

under development

• First USB DRM30 and DRM+ sticks available soon

1. Program distribution by SW, MW / DRM for Rebroadcasting in FM

2. Independent Operation (Independent from Satellites)

3. Extensive coverage with DRM30

4. Digital audio quality and full feature list in the DRM coverage

5. DRM and FM reception of the program possible in the coverage area

6. Low power consumption => stand alone solution in a remote areas with solar energy and battery

7. One DRM transmission can feed two FM audio programs

8. DRM receiver and two full featured FM Exciter included.

9. FM-RF amplifier and antenna can be individually selected, depending on the target area for the coverage (to be added).

10. Ideal solution for FM-Gap filling in remote areas with Low power FM.

11. Listeners can use old FM receiver

Advantages of DRM Re-broadcasting in FM

29

Example

New Zealand

• Radio New Zealand International installed a 100 kW DRM

shortwave broadcast transmitter in Rangitaiki in 2005

• At this moment, Radio New Zealand International is

broadcasting 20 hours per day in DRM to all the

Pacific islands

New application diveemo

Main advantages One single transmitter can reach millions of people anywhere, anytime and with unlimited coverage possibilities

ranging from 100 km² up to well over 5’000’000 km² depending on the transmission system

Diveemo offers free-of-charge reception and is independent of any gatekeepers and third party providers like satellites

and cable networks or internet

Diveemo keep citizens living abroad informed and up-to-date about what is going on in their home country

One video stream can be accompanied by several audio streams, allowing for synchronous multi-language support
