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

21、 Telecommunications Standards Institute (ETSI). NOTE 1: The EBU/ETSI JTC Broadcast 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 Unders

22、tanding also CENELEC, which is responsible for the standardization of radio 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 d

23、omains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva.

24、from the European Commission, to develop a system for the broadcasting of audio and data to fixed, portable or mobile receivers. Their work resulted in the publication of European Standard, ETSI EN 300 401 1, for DAB (see note 2) which now has worldwide acceptance. NOTE 2: DAB is a registered tradem

ETSI EN 300 401 1 describing the transmitted signal, the interface between the broadcasters transmitters and the listeners receiv

28、er. The associated documents, ETSI EN 300 797 2, ETSI EN 300 798 3 and ETSI ETS 300 799 4 describe additional interfaces, which can be used by broadcasters or network providers to build DAB collection and distribution networks. In particular the document ETSI EN 300 797 2 establishes a standard way

29、for transporting Service Components, Service Information and control messages between two entities in a DAB collection network. Because of the openness and flexibility of the Service Transport Interface (STI) standard there is uncertainty regarding the implementation of it. This applies to interoper

30、ability between devices from different suppliers. Practical broadcast scenarios do not always require to implement the full standard, which creates the problem that different suppliers might implement different subsets of ETSI EN 300 797 2. To overcome this problem and to fully exploit the great pot

31、ential of the DAB system, the subject of the present document is to describe implementation levels of the STI standard and to outline their usage. ETSI ETSI TS 101 860 V1.2.1 (2017-08)7 1 Scope The present document establishes guidance in implementation and usage of the functionality described in th

32、e STI standard ETSI EN 300 797 2. Subsets of the STI standard, called STI Levels, are defined in order to make interoperable solutions possible for different suppliers of STI devices. The present document defines the minimum functionality an upstream or downstream entity provides on each level to be

33、 considered compliant with that level.

43、 Network 4 STI Levels 4.0 Introduction The STI Levels describe the STI functionality, i.e. STI-D stream types and STI-C message sets and their usage, that STI entities shall provide to be considered STI level compliant. The levels shall be subsets of ETSI EN 300 797 2 with respect to STI-D(LI) and S

44、TI-C(LI) functionality. A total of three levels is defined. The level requiring the least functionality is called level 1. Higher levels shall fully comprise the lower ones. The levelling proposed in the present document is only valid for the logical part of ETSI EN 300 797 2 and does not apply to p

45、hysical interfaces. Thus an STI capable device may be equipped with one or more physical interfaces, each being capable of providing one of the STI Levels as defined in the present document. 4.1 STI-D(LI) Stream Types 4.1.0 General The STI-D(LI) data stream types classified in ETSI EN 300 797 2, cla

46、use 4.2, are divided into two parts, basic stream types and optional stream types. 4.1.1 Basic Stream Types 4.1.1.0 Definition Basic stream types are: MSC sub-channel audio stream service component; MSC sub-channel data stream service component; ETSI ETSI TS 101 860 V1.2.1 (2017-08)9 MSC sub-channel

47、 data stream made of one or more packet mode service components (and padding); FIC FIG stream Service Information. Table 1 shows which TID and TIDext shall be supported.
