Frequently asked questions What are typical short wave applications of the DRM system?

Typical applications for DRM 1. DRM for crystal clear audio broadcasting for single or multiple programme mode including the option for simulcast

DRM short wave transmitter (DW in Sines) Latest DRM upgrade: Cirrus, DRM Multiprogram Multiplexer Stratus, DRM Versatile Modulator / RF Exciter DRM Monitoring Receiver Cirrus Stratus DW Sines (2006, Portugal) Spectrum mask

Simulcast option testing in India kW M2W transmitter 9 kHz Digital, 9 kHz Analog Simulcast 18 kHz Full Digital

SIMULCAST MW SCS: CONCLUSIONS The simulcast mode tested in New Delhi (AM 97 kW – DRM 2.5 kW) performed very well No noticeable degradation on AM (tested on 5 different AM receiver models) A very good coverage inside the city Some spots (bridges. noise) without coverage despite the mode/power: all those also apply for current commercial AM service The AM and DRM coverage were compared along a radial route up to 100km away from the city: EQUAL RESULTS!! in fact DRM worked well inside the city of Panipat (km. 50) whereas AM failed

Typical applications for DRM 1. DRM for crystal clear audio broadcasting for single or multiple programme mode including the option for simulcast 2. DRM as a distribution network

Example of shortwave DRM Station New Zealand: -Servicing 10 islands with the 100 kW SW DRM Transmitter -The map illustrates the coverage area of the new DRM transmitter -Transmitter and DRM equipment from Thomson Example of DRM application: FM – Rebroadcasting (1)

Example of DRM application: FM – Rebroadcasting (2)

-The strong high quality DRM shortwave signal is an attractive alternative to satellite link broadcasting -With DRM technology, the broadcaster has all his technical means in his own hands and is not dependent on third parties for program distribution -The start-up costs with DRM Shortwave might be higher, but operational costs are significantly less -The use of DRM and shortwave together with rebroadcasting on FM offers a highly interesting, cost-efficient possibility of achieving nationwide as well as local coverage. Example of DRM application: FM – Rebroadcasting (3)

Typical applications for DRM 1. DRM for crystal clear audio broadcasting for single or multiple programme mode including the option for simulcast 2. DRM as a distribution network 3. DRM for multimedia services

Example distance learning system For many countries education is a priority, but not easy to achieve when the students are in remote area, small village, nomad, and when there is no electricity thus internet…

Example distance Learning System What can Digital Radio offer? - Need few or single transmitters (SW) to cover one large area - SW coverage for Australia needs only ONE 250KW SW DRM transmitter - MW coverage needs more high power DRM transmitters to cover same area, thats why SW might be considered as distance learning cost effective solution - Possibility to broadcast sound, data and pictures - DRM is the most cost effective solution, to cover huge areas and reach Millions of people everywhere, every time…

Example distance learning system Protoype receiver with high resolution display available and already shown on various exhibitions Market access expected in Q2/2008

Frequently asked questions Has DRM impact the business for broadcast equipment Manufacturers?

Customers approach us with their visions and ideas –Much more dialogues between customers and manufacturers –Its our daily challenge to convert and implement the customers ideas into products System approach is key for our customers –DRM implementation considering the whole broadcast chain, starting from the studio until analyzing the received signal Thomson is a consultant and system supplier for many projects and new applications of DRM Changes

Conclusion DRM offers a platform for various kinds of application –traditional audio broadcasting in crystal clear FM quality –Multiple programmes on the same channel –Simulcast possibilities for a smooth transition –Data and Multimedia services (Electronic programme guide, Slide show, NewsJournaline®, Traffic Information System, alligned Text messages, … DRM is in operation –Various broadcaster use DRM already –Implementation in various countries ongoing Receivers are available –Various models on the market –More are coming with new features
