Foreword This Technical Report (TR) has been produced by Joint Technical Committee
25、(JTC) of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to Co-ordinate the drafting of standards in the specific field of broadca
26、sting 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 and television receivers. The EBU is a professional association of broadcasting organizations whose work
27、 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 broadcasting area; its headquarters is in Geneva. European Broadcasting Union CH-I218 GRAND SACONNEX (Genev
28、a) Switzerland Tel: +41 22 717 21 11 Fax: +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 servic
29、es. Now comprising over 200 organizations 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. ETSI 6 ETSI TR 102 035 VI .I .I (2002-04) I n t rod uct ion From now
30、on, the DVB Simulcrypt standard is a broadly implemented specification. This situation is due in particular to a significant property of the Simulcrypt solution, offering the option to use in the same head-end multiple CA systems simultaneously with the same content. Actually the standard proposes,
31、first, the definition of a head-end architecture reference model identiSling logically each of its components. But above all, it specifies interoperable interfaces with those of these components supplied by the CA systems. Language The word “shall“ is used in a normative statement that can be verifi
32、ed and is mandatory. The word “should“ is used in the context of a recommendation or a statement that cannot be verified or is not mandatory (it can be optional). 1 Scope The present document provides implementation guidelines for the use and implementation of the DVB Simulcrypt standard. It first t
33、ries to draw attention to the technical questions that need to be answered in setting up a DVB Simulcrypt head- end. It also provides guidelines which are intended to be highly recommended rules and as such, aims to facilitate the efficient and reliable implementation of the Simulcrypt model and of
34、its interfaces. The rules apply to broadcasters, network operators as well as manufacturers. Clause 4 “Architecture“ presents the DVB Simulcrypt Architecture Model as described in TS 103 197 6. Clause 5 “Compliance between version 1 and version 2 of the standard explains how to support compliance be
35、tween both versions 1 and 2 of ECMG and EMMG/PDG protocols. Clause 6 “ECMG SCS Protocol“ fulfils the ECMG protocol description mainly by giving the state diagram. Clause 7 “EMMG/PDGMUX protocol“ fulfils the EMMG/PDG protocol description by giving the state diagram and by clariSling the bandwidth con
36、cept, UDP behaviour and datagram packetization rules. Clause 8 T(P)SIG(P)SIG“ describes profiles for adapting the C(P)SIG protocol implementation to real and simple needs. Clause 9 “SIMF based protocols - Role of NMS“ allows for reducing the use of the MIB for monitoring only. Clause 10 “Error manag
37、ement“ clarifies error management in DVB Simulcrypt protocols. Clause 1 1 “Redundancy management“ sums up uniqueness aspects of protocol parameters and describes basic redundancy policies for functions of the DVB Simulcrypt architecture model. The present document uses the terminology defined in TS
38、103 197 6 and should be read in conjunction with that document.
