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 Euro
17、pean 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 broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Unde
18、rstanding 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
19、 domains. The EBU has active members in about 60 countries 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
20、-led consortium of 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
21、circumstances of 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,
22、 interoperability and future proof specifications. The present document is part 11 of a multi-part deliverable. Full details of the entire series can be found in part 1 i.3. Introduction CPCM is a system for Content Protection cable, satellite, and terrestrial; internet-based services; packaged medi
23、a; and mobile services, among others. CPCM is intended for use in protecting all types of content such as audio, video and associated applications and data. CPCM specifications facilitate interoperability of such content after acquisition into CPCM by networked consumer devices for both home network
24、ing and remote access. This first phase of the specification addresses CPCM for digital Content encoded and transported by linear transport systems in accordance with TS 101 154 i.1. A later second phase will address CPCM for Content encoded and transported by systems that are based upon Internet Pr
25、otocols in accordance with TS 102 005 i.2. ETSI ETSI TR 102 825-11 V1.1.1 (2011-03)71 Scope The present document specifies the Scenarios that are envisaged for the Digital Video Broadcasting (DVB) Content Protection and Copy Management (CPCM) system. It is provided for informative purposes only and
26、will be revised in due course as more scenarios are defined. The present document describes some example approaches of implementation of Content Management Scenarios using DVB-CPCM which support the identified business models. The examples described in the present document are not exhaustive. The pr
27、esent document is informative, and not binding on manufacturers for conformance to the specification. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For
28、non-specific references, the latest version of the reference document (including any amendments) applies.

ETSI ETSI TR 102 825-11 V1.1.1 (2011-03)83 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in TS 102 825
35、-1 i.3 apply. NOTE: In some cases, for ease of reading, definitions are repeated in the present document. In case of conflict, the terms in TS 102 825-1 i.3 will take precedence. For ease of reading by non-specialists, the present document employs some simplified language. Readers seeking detailed t
36、echnical understanding are directed to the normative specifications and definitions of terms. 3.1.1 Instance and Device In the CPCM specifications, much use is made of the term CPCM instance. This is good for the technical specification, as it leaves the option open for manufacturers to support mult
37、iple instances in a single device while remaining conformant. However, in the present document we often use the term Device. This is simply for reasons of ease of understanding for the majority of readers. Unless otherwise stated, within the present document the term device refers to a physical item
38、 of equipment that implements a single CPCM instance. This neither precludes the inclusion of multiple instances in a physical unit, nor the distribution of the functionality of a single CPCM instance across multiple physical units. 3.1.2 CPCM Device The present document is focussed on describing CP
39、CM devices. As such, the term device used in isolation should be read as CPCM Device unless otherwise indicated. 3.1.3 CPCM Content Likewise, where mention is made of content, this should be assumed to be CPCM content unless otherwise indicated. 3.1.4 Server We use the term server for the device act
40、ing as source of the current content. 3.1.5 Player We use the term player for the device acting as sink for the current content. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TS 102 825-1 i.3 apply. NOTE: In some cases, for ease of reading, abbreviations are
41、repeated in the present document. In case of conflict, the abbreviation in TS 102 825-1 i.3 will take precedence. AAA Authorised Authenticated Agent NOTE: Service provider function.

These scenarios cover a broad range of business and usage models, but are not
46、exhaustive. In some cases the scenarios can be combined. In others they may be mutually exclusive. Unfortunately it is not possible to provide a definitive list of all possible combinations. Most scenarios are presented in the same general manner: 1) Business Intent. 2) Suggested USI settings. 3) Op
47、eration of CPCM under these settings. Some basic scenarios are written in close detail. Others assume a degree of understanding of earlier, simpler cases. As an informative document, the intent has been readability rather than technical precision and completeness. In many scenarios, some of the sugg
48、ested USI settings are more important than others. In such cases, the more important values are shown underlined in the USI tables. 4.1 Scenario 1 - Unrestricted Free-to-Air 4.1.1 Business Intent This scenario covers content that is broadcast with minimal restrictions, for example content that is op
49、en for all consumers within the broadcast footprint, and which can also be redistributed to other users both within and beyond the broadcast footprint. NOTE: This scenario applies where content is brought under CPCM control so as to be governed by the rules of a C or Is a member of the same Authorised Domain (AD). CPCM operation will therefore proceed as follows: 1) Request 1 comes from a local device. a) Server 1s application asks its CPCM Acquisition Point (AP) function to provide content to Player 1. b) The AP function establishes tr
