There is an increasing interest worldwide for digital sound broadcasting to vehicular, portable and fixed receivers in the broadcasting-satellite service (BSS) (sound) bands allocated at the World Administrative Radio Conference for Dealing with Frequency Allocations in Certain Parts of the Spectrum (Malaga-Torremolinos, 1992) (WARC-92), and that several satellite-based digital sound broadcasting services for national and supra-national coverage are being considered. Developed for both satellite and terrestrial broadcasting applications in order to allow a common low-cost receiver to be used. Digital System B, originally proposed by Voice of AmericdJet Propulsion Laboratory (VONJPL), was designed to provide maximum efficiency on board a communications satellite. Digital System Ds, also known as the Worldspace system, is primarily designed to provide satellite digital audio and data broadcasting for fixed and portable reception. Digital System DH, also known as the hybrid satellite terrestrial Worldspace system, is designed to provide satellite digital audio and data broadcasting for vehicular, fixed and portable reception by inexpensive common receivers. Digital System E, also known as the ARIB (Association of Radio Industries and Businesses) system, is designed to provide satellite and complementary terrestrial on-channel repeater services for high-quality audio and multimedia data for vehicular, portable and fixed reception.
This Recommendation considering that there is an increasing interest worldwide for terrestrial and satellite digital sound broadcasting (DSB) to vehicular, portable and fixed receivers in the frequency range 30-3 000 MHz for local, regional and national coverage.
