ANSWER: All of the above
- Digital Radio Mondale (DRM) is a set of digital audio broadcasting technologies designed to work over the bands currently used for analogue radio broadcasting including AM broadcasting, particularly shortwave, and FM broadcasting.
- DRM is more spectrally efficient than AM and FM, allowing more stations, at higher quality, into a given amount of bandwidth, using various MPEG-4 audio coding formats.
- DRM has the twin capabilities of analogue and digital transmission, which makes it perfect for simulcast modes.
- The Sam Pitroda Committee set up to suggest a road map for the Prasar Bharati, had struck a cautious note in its report: “Digitalize the present AM radio system to a new digital radio transmission after due evaluation, subject to cost and availability of DRM receivers. In the transition period, FM may be expanded as per demand”. AIR, according to officials, has set 2017 as deadline to achieve total digitization.
