Annex : Order form

ITU SPECIAL PUBLICATION ON DIGITAL
SOUND BROADCASTING (DSB)

		Although VHG/FM services can still provide excellent service to properly-installed fixed receivers, the solution for the future development of sound broadcasting is to provide an entirely new digital sound broadcasting service, designed at the outset to meet all the reception requirements of the diverse listening audiences. Also, a complete digital sound programme chain can be established from studio to domestic receiver.
	New digital systems are designed to provide unimpaired sound broadcast reception to fixed, portable and mobile receivers. The requirement for mobile reception necessitates entirely new emission methods.
	This Special Publication describes the system and service requirements for digital sound broadcasting (DSB) to vehicular, portable and fixed receivers, techniques employed in the digital sound broadcasting systems, and considers relevant planning parameters and sharing considerations. The satellite/terrestrial digital sound broadcasting service concept as well as the hybrid delivery concept.
	The main text of the Special Publication includes the background engineering information that can be used by DSB system and service planners. An effort has been made to include generic information applicable generally to different digital system approaches. The Special Publication structure permits future additions, as appropriate, as new experimental evidence becomes available or new system approaches may appear.
	This publication is considered to be the only comprehensive source of technical information on the subject and is the result of the work of key world-wide experts in the field.
