Digital Radio for All, a round table conference organised by Digital Radio Mondiale (DRM), along with Broadcast Engineering Consultants India Limited (BECIL) in New Delhi on January 31, 2017, discussed benefits of digital radio for stakeholders, including listeners, manufacturers, broadcasters, and regulators, and how it can be scaled up and adopted.
M Venkaiah Naidu, Minister for Information & Broadcasting, while inaugurating the event said, 'Digital radio provides a unique opportunity for stakeholders, both public and private broadcasters to carry forward the government's vision to achieve digital revolution in the country. Digital radio technology provides listeners with significantly improved audio quality and service reliability at an affordable price.'
Retailers can now incorporate digital radio systems in vehicles that provide consumers with significantly improved audio quality and service reliability at an affordable price.
All India Radio has completed the technical installation and upgradation of 37 powerful transmitters in the first phase of digitization of radio broadcast, a project unparalleled in the world. This ensures reduced electric power consumption for all digital transmissions, saving All India Radio and taxpayers significant transmission cost. All India Radio has re-invented itself through its digital transmission.
Emphasizing on the need for traffic advisory services on national highways, Naidu said, 'The next phase of service through AIR FM transmitters needs to be digitized based on the ITU standards to exploit its full potential. The service would offer multiple radio programs, detailed and multi-lingual, on-demand traffic and travel information, and emergency warning services.'
A key and revolutionary feature of DRM is the ability to select from a range of transmission modes. This allows the broadcaster to balance or exchange bit-rate capacity, signal robustness, transmission power, and coverage. The DRM broadcasting system is specifically designed to allow the new digital transmission to co-exist with the current analog broadcasts.
Digital transmission provides crystal clear and better-than-FM sound quality to its listeners, enhancing program choice, free access to textual news, sports, travel, and weather information from the Internet in many languages simultaneously andenables the transmission of emergency warning for immediately alerting the population in case of impending disasters.
From a commercial perspective, the system provides audiences with receivers at an affordable price as well as an attractive package of benefits, which include wider range of services, easier tuning and selection of programming, improved stereo, and surround sound in cars amongst others.
