28、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 broadcast industry stakeholders and consumers. DVB standards cover all aspects of

29、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 and future proof specifications. The present document is part 7 of a multi-part d

30、eliverable. 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 digital content delivered to consumer products. CPCM manages content usage from acquisition into the CPCM system until final consumption, or

31、export from the CPCM system, in accordance with the particular usage rules of that content. Possible sources for commercial digital content include broadcast (e.g. cable, satellite, and terrestrial), Internet-based services, packaged media, and mobile services, among others. CPCM is intended for use

32、 in protecting all types of content - 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 networking and remote access. This first phase of the specification address

33、es 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 Protocols in accordance with TS 102 005 i.2. ETSI ETSI TS 102 825-7 V1

The present document defines messages and state machines that together define the conformant behaviour of an implementation. The present document also defines a mandatory method for performing ADSE. Additionally

43、household to establish and Join a DVB CPCM Authorized Domain (AD). It also provides an interoperable means of managing that AD. Basic expectations on ADM are given in TS 102 825-2 i.3. 4.1 ADM in the CPCM System Figure 1 shows how ADM fits into the CPCM Reference Model. Figure 1: ADM in the CPCM Ref

44、erence Model ETSI ETSI TS 102 825-7 V1.2.1 (2011-02)9Figure 2 provides another view of ADM within a CPCM implementation. It identifies that there are three key internal sub-systems with which the ADM Sub-system must communicate. Figure 2: ADM Interfaces to other CPCM Sub-systems It would be possible

45、 to build a CPCM implementation that strictly follows the architecture in figure 2, but this is not required. For reasons of clarity the present document is written in terms of the interfaces in figure 3. Figure 3: ADM Interfaces ADM1 is the interface which is used to communicate with peer ADM Insta

46、nces in other devices, via a Network Adaptation function that is specific to each network technology. EXAMPLE: On DVB-HN (Home Network) conformant systems, ADM messages will be transferred using the UPnP protocols. However, for other situations such as serial Smartcard or CI interfaces, ADM messages

47、 will be transferred without UPnP support. The present document includes a formal description of the ADM1 interface. ADM2 is the interface to the Security Tools Sub-system of CPCM. The present document defines the normative behaviour of the Security Control and provides an informative API for use ac

48、ross this interface. ADM3 is the informative interface between a Device Application and the ADM. ETSI ETSI TS 102 825-7 V1.2.1 (2011-02)104.2 Local ADM Master and Domain Controller 4.2.1 ADM Local Master Concept and Requirements A single CPCM Instance acts as a temporary Local ADM Master for the AD

49、members in the Local network. The ADM Local Master has no specific additional data (i.e. the same AD data is replicated to all Instances in the AD). The Local Master can be replaced at any time to avoid a single-point-of-failure. Figure 12 and clause 5.1.7 describe how to determine which Instance fulfils this role at any given moment. The basic behaviour is as follows: The first Instance to create the Authorized Domain immediately becomes the Local Master. When an Instance attempts to discover available ADs or properties of connected Instan
