Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisat
23、ion 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 broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite
24、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 activities in the technical, leg
25、al, 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.

26、o Broadcasting Project (DVB) is an industry-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
27、solutions that meet the needs and economic 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
28、 in 1993 to provide global standardisation, interoperability and future proof specifications. The present document is part 3 of a multi-part deliverable. Full details of the entire series can be found in part 1 1. Introduction CPCM is a system for Content Protection and Copy Management of commercial
29、 digital content delivered to consumer products. CPCM manages content usage from acquisition into the CPCM system until final consumption, or export from the CPCM system, in accordance with the particular usage rules of that content. Possible sources for commercial digital content include broadcast
30、(e.g. cable, satellite, and terrestrial), Internet-based services, packaged media, and mobile services, among others. CPCM is intended for use in protecting all types of content - audio, video and associated applications and data. CPCM specifications facilitate interoperability of such content after
31、 acquisition into CPCM by networked consumer devices for both home networking 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
32、Content encoded and transported by systems that are based upon Internet Protocols in accordance with TS 102 005 i.2. ETSI ETSI TS 102 825-3 V1.2.1 (2011-03)61 Scope The present document specifies the Usage State Information (USI) for the Digital Video Broadcasting (DVB) Content Protection and Copy M
33、anagement (CPCM) system. Additionally, the present document specifies USI-related Auxiliary Data that will be carried along with the USI by mechanisms to be specified further by CPCM. NOTE: USI has been designed to accommodate a variety of business models and regulatory regimes. The existence of any
34、 particular field of USI does not imply that it will be asserted by a particular business or that it will be allowed to be asserted. 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
35、the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference. NOTE: While any hyper

42、2 825-1 1 apply. 4 Usage State Information General Requirements 4.1 Definition and application The DVB CPCM Usage States Information (USI) is CPCM Content metadata that signals the Authorized Usage for that particular Content Item. Authorized Usage is the permitted usage of CPCM Content, consisting
43、of the set of Usage Rules applied to that Content. Content is data that is to be protected by the CPCM System. This is generally audio-visual content plus optional accompanying data, such as subtitles, images/graphics, animations, web pages, text, games, software (both source code and object code),
44、scripts or any other information which is intended to be delivered to and consumed by a user. Usage Rules are the particular operations or behaviours that are within the scope of Content Protection and Copy Management and are to be controlled by the CPCM System through CPCM specifications and C e.g.
45、 if the resulting CPCM USI are constrained over time (e.g. rental window). 4.5 Content within DVB CPCM System In the case of a transfer of Content from one DVB CPCM Instance to another DVB CPCM Instance, all of the USI shall be securely conveyed and shall remain securely bound to the Content. Certai
46、n USI fields may change through a secure process, for example: transition from Copy Once to Copy No More; transition from Zero Retention not asserted to Zero Retention asserted; modification of a USI field by the Rights Holder as defined in clause 4.1, such modification to be performed through a Con
47、tent Licence re-Acquisition by an Authorized Authenticated Agent; and transition from VPA asserted to VPA not asserted upon first Consumption of Content and modification of VWA and View Window accordingly. Changes to USI fields are only permitted under circumstances defined in CPCM System specificat
48、ions (TS 102 825-4 2). The conditions and mechanisms by which these changes occur are beyond the scope of the present document. ETSI ETSI TS 102 825-3 V1.2.1 (2011-03)94.6 Propagation Controls The DVB CPCM USI includes a variety of propagation USI that enable Copying, Movement and Viewing of Content
49、 within defined groups of DVB CPCM compliant devices. Copying and Movement are controlled together and use the same USI fields. Viewing, or Consumption, can be controlled independently and therefore uses separate USI fields. These USI fields are specified in detail in the following clauses. This clause provides an overview of the logical and physical groups of devices and the hierarchical, precedence and transitional relationships between the various groups of devices.
