With AIR gearing up to launch this digital service, this dream is surely close to becoming a reality. Radio is an old-age companion to mankind. In the last decade, there have been many developments in radio broadcasting, and it is on the verge of a digital convergence. There had been quite a few formats on air, and certainly a few more will come up till one or more of them becomes world standard in radio broadcasting. In India, the first digital broadcasting was stated in the DAB (Digital Audio Broadcasting) format, closely followed by the digital satellite radio service by WorldSpace. The (Direct-to-Home) services for TV also carry digital radio broadcasts, and probably, in a few years, DRM (Digital Radio Mondiale) will make its presence-free. DAB - the most advanced technology in radio since the introduction of FM stereo - provides interference-free reception and high quality sound, easy to use receivers and an unlimited potential for wider listening through many additional stations, services and developments. If we listen to FM radio in the car, there are hisses and plops as we drive along. That is caused by multipath interference when the FM signal bounces off buildings, trees and hills and arrives at our receivers out of phase with the main signal, confusing the transmission. But in the DAB receiver, there is a processor that sorts through the myriad multipath signals and other distortions t6o enhance the main signal. The means that even in the most difficult listening environments, like the centre of the city of the high-rise buildings, the DAB signal remains perfect. As the third generation radio, the DAB system is paving the way for the digital era of broadcasting. This system was developed by the Eureka 147 project - an international consortium of broadcasters, network operators, consumer electronic industries and research institutes. They came together to develop the DAB standard, which is currently being implemented worldwide. DAB is broadcast on terrestrial networks, with prospects for satellite broadcasting in the future. DAB can be received used a just tiny non-directional stub antenna. High quality radio programs can also be received in cars without any annoying interference and signal distortion. DAB can carry audio, text, pictures, data and even video to some extent. DAB complies with the tough requirements of the digital age emerging before us. DAB can be transmitted on frequencies from the FM band (88-108 MHz), but the services that have been introduced in Europe, Canada and Australia, together with pilots in India, are using other frequencies. Some countries, including UK, are using Band III (around 221 MHz), formally used for black and white television signals. Others like Germany and Canada are using L-Band (1452-1492 MHz). DAB receivers currently in the market can receive both Band III and L-Band transmissions. In 1992, the World Administrative Radio Conference, he internationally recognized meeting that assigns all the world radio spectrum usage, allocated the L-Band frequency range to digital broadcasting, both terrestrial and satellite. All DAB receivers will have digital displays including some with large liquid crystal screens, and broadcasters will have the option to transmit additional Program Associated Data (PAD). On the broadcast front, DAAB requires a fragment of the power otherwise required by the analog broadcasting for the same coverage area. Over three hundred million people around the world can now receive more than 585 different services. Commercial DAB receivers have now been on the market since 1998. There are more than 32 different DAB receivers commercially available abroad. All India Radio started regular experimental DAB transmission in New Delhi in April 1997. AIR will be launching a pilot DAB service with 1 kW transmitter in Delhi this year. The transmission shall carry 6 stereo channels in addition to PAD and Data Services. The pilot DAB will be extended to Chennai, Mumbai and Kolkata by the year 2005-06. (From "AV MAX" - a monthly publication on audio visual technologies.) Regds.
