ETSI ETSI TS 102 822-5-2 V1.2.1 (2006-01) 5 Introduction “TV-Anytime“ (TVA) is a synchronized set of specifications established by the TV-Anytime Forum. TVA features enable the search, selection, acquisition and rightful use of content on local

21、and/or remote personal storage systems from both broadcast and online services. TS 102 822-1 1 and TS 102 822-2 2 set the context and system architecture in which the standards for Metadata, Content referencing, Bi-directional metadata and Metadata protection are to be implemented in the TV-Anytime

22、environment. TS 102 822-1 1 provides benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the specification enable key business applications. TS 102 822-2 2 presents the TV-Anytime System Architecture. These two documents are placed ahead of the othe

23、rs for their obvious introductory value. Note that these first two documents are largely informative, while the remainder of the series is normative. The features are supported and enabled by the specifications for Metadata (TS 102 822-3 sub-parts 1 3, 2 4, 3 5 and 4 6), Content Referencing (TS 102

24、822-4 7), Rights Management (TS 102 822-5 sub-parts 1 8 and 2 (the present document), Bi-directional Metadata Delivery (TS 102 822-6 sub-parts 1 9, 2 10 and 3 11) and Protection (TS 102 822-7 12), Interchange Data Format (TS 102 822-8 13) and Remote Programming (TS 102 822-9 14). The present documen

25、t is to be used by manufacturers, service providers and content providers for the implementation of the features of the TV-Anytime specifications. The present document specifies the methods for binding RMP Information to content in different environments. ETSI ETSI TS 102 822-5-2 V1.2.1 (2006-01) 6

26、1 Scope Binding of Rights Management and Protection Information is a component of the TV-Anytime Rights Management and Protection system suite of specifications. When used in conjunction with the RMPI specification as components of an end-to-end RMP system, binding ensures that RMPI is appropriately

27、 applied. TVAF RMP defines Binding as the process of creating a strong association between a given set of RMPI and the content to which it applies. TVAF RMP defines Secure Binding as a Binding adequate to ensure that bound RMPI cannot be reassigned to unintended content without detection. Non-secure

28、 binding is binding which is not secure, and includes insufficient mechanisms to protect against tampering and/or modifications to RMPI. The present document specifies methods for both Secure Binding and Non-Secure Binding. Different binding methods are given for both content broadcast in the clear

29、(e.g. free-to-air broadcast) and scrambled content (e.g. content protected by CA or DRM). Different binding methods allow for the detection of RMPI tampering and/or unauthorized modifications to the binding. RMPI under such conditions is treated as invalid by the RMP system. Compliance bodies will s

30、pecify RMP system detection obligations and required behaviours when either of the conditions (tampering/modification) occur. It is mandatory that RMPI binding be verified before RMPI may be acted upon by the RMP system. All the proposed binding methods in principle enable the binding of multiple RM

31、PI, if so required. The implementation of the present document requires the use of cryptographic technologies, however, the selection of such technologies are left to the compliance body. These include but are not limited to: ciphers, trust models, key management and watermark algorithms. 2 Referenc
