NOTE
20、: 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 Understanding also CENELEC, which is responsible for the sta
21、ndardization 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 domains. The EBU has active members in about 60 countri
22、es in the European broadcasting area; its headquarters is in Geneva.

23、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 circumstances of broadcast industry stakeholders and con
24、sumers. 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, interoperability and future proof specifications. The p

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 t
26、he 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 (e.g. cable, satellite, and terrestrial), Internet-based services, packaged media, and mobile servi
27、ces, 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 acquisition into CPCM by networked consumer devices for both home networking and remote access. Th
28、is 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 Protocols in accordance wit

38、itectural framework for the DVB Content Protection and Copy Management (CPCM) System. The Reference Model is described on the basis of the CPCM Abbreviations, Definitions and Terms defined in TS 102 825-1 1. It provides a technology-agnostic basis for the CPCM System. The CPCM System provides an int
39、eroperability platform for the protection and management of “commercial“ content, i.e. not user-created content, in the consumer environment. The typical field of application of the CPCM System is shown in Figure 1. Figure 1: Scope of CPCM The consumer environment contains many different kinds of de
40、vices that allow the user to enjoy content in different situations, for example stationary devices in the home, the same at any secondary residence, mobile devices in the car, or handheld portable devices. Content can be delivered to the consumer by various means, for example, via broadcast (cable,
41、satellite or terrestrial), the Internet, from packaged media, or mobile delivery, as shown in Figure 1. CPCM intends to provide a protection and management environment that is relevant for all delivery channels, for all content usage scenarios and business models that are familiar to the user, and f
42、or those to come, on whatever types of device are deployed to let users access content. It is impossible to document the CPCM Reference Model sufficiently in a single diagram, thus the CPCM Reference Model consists of several aspects, or views, which taken together deliver the full picture. ETSI ETS
43、I TS 102 825-2 V1.2.1 (2011-03)9Clause 5 gives a high-level introduction to each of the various aspects that together define the CPCM System. Subsequent clauses then expand on each of these aspects to give the complete CPCM Reference Model. 5 CPCM System This clause gives an overview of the various
44、elements of the CPCM System. Figure 2 shows the basic conceptual model of the CPCM System. Figure 2: CPCM System Conceptual Diagram It is intended that the CPCM System will be implemented for different methods of Input Content delivery to the consumer including free-to-air television, pay television
45、 and purchased media, on consumer equipment provided by many manufacturers, deploying various technologies to exchange and store content. The basic CPCM content management model is that Input Content enters the CPCM System to become CPCM Content. CPCM Content is managed and protected within the CPCM
46、 System. CPCM Content leaves the CPCM System when it is Consumed by the user, or when Exported to another system. CPCM Functional Entities. The Reference Model defines the set of five abstract content management functions - Acquisition, Storage, Processing, Consumption, and Export - which cover all
47、relevant content usage scenarios in the consumer environment. These functions map to the five CPCM Functional Entities - Acquisition Point, Storage Entity, Processing Entity, Consumption Point, and Export Point. Figure 3 shows the view of the CPCM System in terms of the set of abstract Functional En
48、tities. ETSI ETSI TS 102 825-2 V1.2.1 (2011-03)10Thus Input Content that enters the CPCM System does so by being Acquired at an Acquisition Point, by a CPCM Device that implements that Acquisition Point, to become CPCM content. CPCM Content can be Stored or Processed by the corresponding Functional
49、Entities (Storage Entity, Processing Entity), implemented on a CPCM Device. CPCM Content leaves the CPCM System when it is Consumed, at a Consumption Point, or Exported, at an Export Point. Again, these Functional Entities can be implemented inside any CPCM Device. Figure 3: CPCM Functional Entities The CPCM Functional Entities and basic CPCM Content types are described further in clause 6. CPCM Device A CPCM Device is any device that implements CPCM functionality in a compliant manner. As shown in Figure 2, the CPCM System can be considered a
