Foreword This European Standard (EN) 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 St

24、andards Institute (ETSI). The work of the JTC was based on the studies carried out by the European DVB Project under the auspices of the Ad Hoc Group on DVB-SH of the DVB Technical Module. This joint group of industry, operators and broadcasters provided the necessary information on all relevant tec

25、hnical matters (see bibliography). NOTE: 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 CE

26、NELEC, 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 domains. The EBU

28、f broadcasters, manufacturers, network operators, 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

29、broadcast industry stakeholders and consumers. 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

31、onflicting National Standard (dow): 30 September 2012 ETSI ETSI EN 302 583 V1.2.1 (2011-12)61 Scope The present document specifies a transmission system for hybrid satellite and terrestrial digital television broadcasting to mobile terminals. It is derived from the DVB-T 1 and DVB-H 6 system specifi

32、cation, respectively designed for digital television terrestrial broadcasting towards fixed and mobile terminals and DVB-S2, 2 designed for digital satellite broadcasting towards fixed terminals. The purpose of the DVB-SH standard is to provide an efficient transmission system using frequencies belo

33、w 3 GHz suitable for Satellite Services to Handheld devices, in terms of reception threshold and resistance to mobile satellite channel impairments. The system relies on a hybrid satellite/terrestrial infrastructure. The signals are broadcast to mobile terminals on two paths: A direct path from a br

34、oadcast station to the terminals via the satellite. An indirect path from a broadcast station to terminals via terrestrial repeaters that form the Complementary Ground Component (CGC) to the satellite. The CGC can be fed through satellite and/or terrestrial distribution networks. The system includes

35、 two transmission modes: An OFDM mode based on DVB-T standard 1 with enhancements. This mode can be used on both the direct and indirect paths; the two signals are combined in the receiver to strengthen the reception in a SFN configuration. A TDM mode partly derived from DVB-S2 standard 2, in order

36、to optimize transmission through satellite towards mobile terminals. This mode is used on the direct path only. The system supports code diversity recombination between satellite TDM and terrestrial OFDM modes so as to increase the robustness of the transmission in relevant areas (mainly suburban).

37、The present document specifies the digital signal format and the digital signal modulation and coding in order to allow compatibility between pieces of equipment developed by different manufacturers. Signal processing at the modulator side is described in details, while processing at receiver side i
