Foreword This Technical Report (TR) 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 Standa

37、rds Institute (ETSI). The present document is supplementary to the earlier document TR 101 190 i.5. The present document extends the scope of the implementation guidelines to include handheld reception as defined by EN 302 304 i.2. Many of the items specified in TR 101 190 i.5 are not reproduced in

38、the present document, as they are already available, even though they may be relevant to the implementation of a DVB-H network. 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 J

39、TC 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 is a professional association of broadcasting organizations whose work includes the co-ordination of its members

40、 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 in Geneva.

41、+41 22 717 24 81 Founded in September 1993, the DVB Project is a market-led consortium of public and private sector organizations in the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations

42、from more than 25 countries around the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry. Introduction The present document gives the first guidelines for the implementation of Digital Video Broadcasti

43、ng Handheld (DVB-H) transmission networks. The present document describes the main features of the DVB-H system and gives guidelines for setting up networks and services. Updates to the present document will be produced when more results from DVB-H compliant hardware tests and experience from field

44、trials become available. ETSI ETSI TR 102 377 V1.4.1 (2009-06) 8 Document summary An outline of the DVB-H system is introduced in clause 4, describing the main features of time slicing, multiprotocol encapsulation forward error correction (MPE-FEC), the additional (to DVB-T) 4K mode and in-depth int

45、erleavers, and DVB-H signalling. Clause 5 introduces the link layer elements of the DVB-H system specification. These are time slicing and MPE-FEC. In this clause there is a description of the main issues and a discussion on how to implement the DVB-H elements. Clause 6 introduces the physical layer

46、 elements of the DVB-H system specification that are additional to the DVB-T standard. NOTE: As seen in the main text, time slicing and DVB-H signalling is mandatory in a DVB-H system. Other technological elements are optional to use. Compatibility issues (to DVB-T) are discussed in detail in clause

47、 7. DVB-H services and usage scenarios are presented in clause 8. This clause includes important issues such as sharing with DVB-T and MPEG-2 services and handover considerations. Clause 9 is devoted to DVB-H networks. The following issues are discussed: Network configurations, SI issues, on-channel

48、 repeaters and general guidelines for the use of DVB-H in 5 MHz channel bandwidths. Clauses 10 and 11 provide preliminary information about the DVB-H reference receiver and network planning. Finally two annexes are included, the first shows the terminal categories (used in clause 11) and the other o

49、utlines the implications of having “convergence terminals“ in which DVB-H and GSM/UMTS technologies co-exist. ETSI ETSI TR 102 377 V1.4.1 (2009-06) 9 1 Scope The present document provides guidelines for the use and implementation of ETSI Digital Video Broadcasting Handheld (DVB-H) standard i.2 in the context of providing an efficient way of carrying multimedia services over digital terrestrial broadcasting networks to handheld terminals. The document should be read in conjunction with the DVB-T Implementation Guidelines (TR 101 190 i.5) since many transmissi
