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:

13、 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 Understanding also CENELEC, which is responsible for the stan

14、dardization 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 domains. The EBU has active members in about 60 countrie

15、s in the European broadcasting 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 Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network o

16、perators, software developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and cons

17、umers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. Introd

18、uction The present document specifies the transmission system using ETSI Digital Video Broadcasting standards to provide an efficient way of carrying multimedia services over hybrid satellite and terrestrial (DVB-SH) networks at frequencies below 3 GHz to a variety of mobile and fixed terminals havi

19、ng compact antennas with very limited directivity. Target terminals include handheld (PDAs, mobile phones, etc.), vehicle-mounted, nomadic (laptops, palmtops, etc.) and stationary terminals. The present document identifies ETSI standards that specifiy functionalities and parameters required for deli

20、vering compliant services. The DVB-SH standard provides a universal coverage by combining a Satellite Component (SC) and a Complementary Ground Component (CGC): in a cooperative mode, the SC ensures geographical global coverage while the CGC provides cellular-type or terrestrial broadcast-type cover

21、age. All types of environment (outdoor, indoor) can then be served, either using the SC and/or the CGC. A typical DVB-SH system (see figure 1) is based on a hybrid architecture combining a Satellite Component and, where necessary, a CGC consisting of terrestrial repeaters fed by a broadcast distribu

22、tion network of various kinds (DVB-S2, fiber, xDSL, etc.). ETSI ETSI TS 102 585 V1.2.1 (2011-09)5The repeaters may be of three kinds: TR(a) are broadcast infrastructure transmitters which complement reception in areas where satellite reception is difficult, especially in urban areas; they may be col

23、located with mobile cell site or standalone. Local content insertion at that level is possible, relying on adequate radio frequency planning and/or waveform optimizations. TR(b) are personal gap-fillers of limited coverage providing local on-frequency re-transmission and/or frequency conversion; typ

24、ical application is indoor enhancement under satellite coverage; no local content insertion is possible. TR(c) are mobile broadcast infrastructure transmitters creating a “moving complementary infrastructure“. Depending on waveform configuration and radio frequency planning, local content insertion

25、may be possible. Service local service(s) may be available in CGC if its capacity extends the SC capacity, or if hierarchical modulation is used; regular and low latency services are available in both SC and CGC. The combination of both system architecture and these receiver classes leads to four te

46、efinition 4.1 General DVB-SH is a broadcast transmission system for datagrams, including IP. They may contain data that pertain to multimedia services, file-downloading services, or to other services not mentioned here. DVB-SH standard specification is composed of: a physical layer specified in 1; a

47、 link layer specified in 1, 5 and 6; a PSI and SI service information layer specified in 3,4; an IP Datacast service information layer specified in 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 and 17; an implementation guideline 2 where additional important information about synchronization between modulator

48、s of the CGC and SC and further information and recommendations about how to use and select the appropriate parameters of DVB-SH are provided. 4.2 DVB-SH physical layer DVB-SH physical layer shall follow reference 1 that defines the waveform. Although reference 1 specifies the available features of

49、the DVB-SH waveform, it is expected that various market conditions, system requirements and regulatory constraints will yield various system implementation and deployment strategies of following key features: OFDM modulation for the CGC, and either OFDM or TDM modulations for SC with the flexibility for network providers to choose between SH-A and SH-B, according to satellite characteristics and regulatory considerations. Possible choice is QPSK, 8PSK, 16APSK for
