Foreword This Technical Specifi
16、cation (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to c
17、o-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU i
18、s a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is
19、 in Geneva. European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 Introduction The frequency bands used for broadcasting below 30 MHz are: Low Frequency (LF) band - from 148,5 kHz to 283,5 kHz, in ITU Region 1 1 only; Medium Frequency (MF
20、) band - from 526,5 kHz to 1 606,5 kHz, in ITU Regions 1 1 and 3 1 and from 525 kHz to 1 705 kHz in ITU Region 2 1; High Frequency (HF) bands - a set of individual broadcasting bands in the frequency range 2,3 MHz to 27 MHz, generally available on a Worldwide basis. These bands offer unique propagat
21、ion capabilities that permit the achievement of: large coverage areas, whose size and location may be dependent upon the time of day, season of the year or period in the (approximately) 11 year sunspot cycle; portable and mobile reception with relatively little impairment caused by the environment s
22、urrounding the receiver. There is thus a desire to continue broadcasting in these bands, perhaps especially in the case of international broadcasting where the HF bands offer the only reception possibilities which do not also involve the use of local repeater stations. ETSI ETSI TS 101 968 V1.3.1 (2
23、009-04) 5 However, broadcasting services in these bands: use analogue techniques; are subject to limited quality; are subject to considerable interference as a result of the long-distance propagation mechanisms which prevail in this part of the frequency spectrum and the large number of users. As a
24、direct result of the above considerations, there is a desire to effect a transfer to digital transmission and reception techniques in order to provide the increase in quality which is needed to retain listeners who, increasingly, have a wide variety of other programme reception media possibilities,
25、usually already offering higher quality and reliability. In order to meet the need for a digital transmission system suitable for use in all of the bands below 30 MHz, the Digital Radio Mondiale (DRM) consortium was formed in early 1998. The DRM consortium is a non-profit making body which seeks to
26、develop and promote the use of the DRM system worldwide. Its members include broadcasters, network providers, receiver and transmitter manufacturers and research institutes. More information is available from their website (http:/www.drm.org/). ETSI ETSI TS 101 968 V1.3.1 (2009-04) 6 1 Scope The pre
27、sent document gives the data application identifiers needed for Digital Radio Mondiale (DRM) system data applications and provides the references to the associated specifications. It provides details on data application transport and the mappings required to carry application specified for Digital A

Service Description Channel (SDC): channel of the multi
39、plex data stream which gives information to decode the services included in the multiplex NOTE: The SDC also provides additional information to enable a receiver to find alternative sources of the same data. 3.2 Abbreviations For the purposes of the present document, the following abbreviations appl

42、nd alone. For stand alone data services, the FAC contains an application identifier field which allows receivers to scan the frequency bands to find a particular data service. For all data applications, the SDC data entity type 5 - application information - shall be coded according to ES 201 980 1 a
43、nd the descriptions provided in the present document. The DRM multiplex may contain up to four streams in the MSC, each carrying audio or data service information. Using the SDC data entities type 9 and/or 5, each DRM service can reference: - one audio stream; - one data stream (or one data sub-stre
44、am if the stream is in packet mode); or - one audio stream and one data stream (or one data sub-stream) as programme associated data. 4.1 New data applications As new data applications are defined and standardized, the present document will be revised to reflect those changes. The content of the pre
45、sent document is maintained by the DRM Consortium. Applications for the inclusion of a new data application should be made to the address below: Digital Radio Mondiale DRM Project Office Postal Box 360 CH - 1218 Grand-Saconnex Geneva - Switzerland Tel: +41 22 717 2718 Fax: +41 22 747 4718 E-mail: ap
46、plicationsdrm.org Applications for the inclusion of a new data application shall clearly state the purpose along with all necessary definitions of required fields. Support from other organizations for the request should be cited. The proposal shall be circulated to all members of the DRM consortium
47、for a 30 day comment period. If there are no adverse comments, then the application, as amended by any helpful editorial suggestions will be accepted and published within a further 30 days on the DRM website. If there are adverse comments, then the application will be considered by the DRM Technical
48、 Committee at its next plenary meeting following the comment period. The applicant will be given an opportunity to describe their proposal and reasons for it. The decision of the DRM Technical Committee will be final and if the application is accepted, as amended by any helpful editorial suggestions
49、, it will be published within 30 days on the DRM website. The present document will be amended as required via the normal ETSI process. 4.2 FAC Application identifiers The FAC service information contains a field to indicate the data application identifier. This is to allow a scanning receiver to quickly decide if the application is useful or whether to continue to scan. The application identifier is only available to stand alone data services, not data applications carried with audio services. Table 1 provides the in
