23、. Foreword This Technical Specification (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 1: The EBU/ETSI JTC Bro
24、adcast was established in 1990 to co-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
25、and television receivers. The EBU is 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 bro
26、adcasting area; its headquarters is in Geneva. European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 The Eureka Project 147 was established in 1987, with funding from the European Commission, to develop a system for the broadcasting of au
27、dio and data to fixed, portable or mobile receivers. Their work resulted in the publication of European Standard, ETSI EN 300 401 3, for DAB (see note 2) which now has worldwide acceptance. NOTE 2: DAB is a registered trademark owned by one of the Eureka Project 147 partners. The DAB family of stand
28、ards is supported by World DAB, an organization with members drawn from broadcasting organizations and telecommunication providers together with companies from the professional and consumer electronics industry. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should
29、not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction Th
30、e present document defines how the SPI data will be transported, compressed and profiled such that a good user experience can be achieved using limited broadcast capacity. Using a combination of SPI profiles it is possible that a range of features could be supported in devices, including: Navigation
31、 and selection of services and programmes. The display of schedules at varying levels of detail for programmes from a range of services. ETSI ETSI TS 102 371 V3.2.1 (2016-05)7 The display of schedules, with programmes and events ordered into particular groups. Searching through current, future and p
32、ast programme listings, including on-demand content (Filecast). Timed recording of individual programmes, or of groups of programmes and themed or similar programming. The present document is compatible with the hybrid digital radio SPI, ETSI TS 102 818 (V3.1.1 or later) 1. ETSI ETSI TS 102 371 V3.2
33、.1 (2016-05)8 1 Scope The present document defines how the XML schema data model for Service and Programme Information (SPI) (ETSI TS 102 818 1) should be compressed, profiled and broadcast. Within the present document the term “DAB“ is used to refer to the Digital Audio Broadcasting standard (ETSI
34、EN 300 401 3) and “DRM“ is used to refer to the Digital Radio Mondiale standard (ETSI ES 201 980 6). In respect to previous versions of the present document, hybrid radio provisions have been added to allow a seamless experience for users when consuming radio services delivered by digital radio broa
35、dcasting systems (DAB, DRM) or IP or a combination of both. The use of the present document allows content to be created once by the service provider for delivery by both mechanisms and allows manufacturers to implement devices with many common elements. 2 References 2.1 Normative references Referen

45、cated to a DAB ensemble and intended to allow unambiguous worldwide identification of that ensemble entity reference: group of characters used in text strings as a substitute for a single specific character, e.g. this provides for easy specification of loops and conditional data structures.
