The present document is part 5 of a multi-part deliverable covering

15、Broadcast and On-line Services: Search, select, and rightful use of content on personal storage systems (“TV-Anytime Phase 1“), as identified below: Part 1: “Phase 1 Benchmark Features“; Part 2: “System description“; Part 3: “Metadata“; Part 4: “Content referencing“; Part 5: “Rights Management and P

Introduction The present document is based on a submission by the TV-Anytime forum (http:/www.tv-anytime.org). The present doc

17、ument specifies the minimum set of usage rules and conditions required to enable protection of broadcast digital television content within a TVA Rights Management and Protection (RMP) compliant domain. When associated with a broadcast signal, RMP Information (RMPI) for Broadcast Applications is call

18、ed RMPI-Micro Broadcast (RMPI-MB). When associated with content present in a TVA RMP compliant domain (post broadcast/acquisition) it is called RMPI-Micro (RMPI-M). RMPI for Broadcast Applications can be used in conjunction with both free-to-air broadcasts and broadcasts protected by CA or DRM syste

20、cifications established by the TV-Anytime Forum. TVA Phase 1 features enable the search, selection, acquisition and rightful use of content on local and/or remote personal storage systems from both broadcast and online services. The features are supported and enabled by the specifications for Metada

21、ta, Content Referencing, Rights Management and Bi-directional Metadata Delivery Protection, TS 102 822-3 2, TS 102 822-4 3, TS 102 822-5 (the present document), TS 102 822-6 4 and TS 102 822-7 5 respectively. All Phase 1 Features listed in TS 102 822-1 1 are enabled by the normative TV-Anytime tools

22、 specifications. This list of Phase 1 Features is to be used as guidance to manufacturers, service providers and content providers regarding the implementation of the Phase 1 TV-Anytime specifications. There will be further TV-Anytime phases published and Business Models for Post-Phase 1 are current

23、ly being defined to include Private and public domains, portable recordable media, super distribution (legal sharing of content between consumers), peripheral device support and mobile devices, amongst others.

24、 of RMPI-Micro Broadcast and RMPI-Micro, is a component of the TV-Anytime Rights Management and Protection system suite of specifications. The present document provides the semantics, syntax and encoding for the usage rights, controls and permissions to be conveyed in RMPI-MB and RMPI-M. 2 Reference

36、B rights are positively asserted and never implied. These rights are granted to the RMP System and not to a person. When a right is exercised, asserted conditions are validated. If those asserted conditions are not met then the right cannot be exercised, e.g. a user could hit pause without asking fo

37、r permission, however hitting play after pause would cause the conditions to be validated and the rights to be acquired. If conditions are not asserted, then they do not constrain the rights. 4.2 Operational approach The RMPI-MB and RMPI-M focus on the usage of content as opposed to the movement of

38、content. As a consequence there is no notion of copy within the secure RMP-compliant domain as only those principals that have been granted rights to use the content are given access to the content under the conditions expressed in RMPI-MB and RMPI-M. Usage of the content under the protection of the

39、 RMP system is explicitly defined and regulated. In the event that the broadcaster wishes to allow the content to leave the protection of the RMP system it is expressible with RMPI-MB and RMPI-M as an Export with appropriate conditions. One significant reason to permit this is to allow content to be

40、 consumed on legacy devices. ETSI ETSI TS 102 822-5 V1.1.1 (2005-03) 8 4.3 Compliance TV-Anytime RMP does not mandate specific implementations or compliance and robustness rules. There are certain parameters in the specification that are left for assignment by the compliance bodies; for example geog

41、raphic control, RMP domain identifier, single point of control identifier and security level. It is anticipated that compliance bodies that adopt the specification will define implementation requirements and associated compliance regimes to meet the needs of their respective environments. Compliance

42、 bodies may even choose an alternative encoding for RMPI-M or MB (e.g. XML expression given in annex A). 5 RMPI - Micro Broadcast and RMPI - Micro semantics 5.1 Principals Table 1 gives the Principals that can be used by a broadcaster when granting rights with RMPI-MB and RMPI-M. Table 1: Principals

43、 being used by broadcasters Principal Definition Receiving Domain The receiving domain is the first TVA RMP-compliant domain that receives the content and associated RMPI-MB via broadcast. Once the content is in the domain, the receiving domain is explicitly identified. Any Domain Any TVA RMP-compli

44、ant domain that can respond to the usage conditions stated within RMPI-MB and RMPI-M. 5.2 Rights The set of rights listed in table 2, depending on their applied conditions, can be used to enable users to access content via a range of devices under a variety of different usage models. Note that terms

45、 PLAY and EXPORT below can both be used to enable content viewing, but under different consumption environments or constraints. ETSI ETSI TS 102 822-5 V1.1.1 (2005-03) 9 Table 2: Rights Right Description Play “Play“ is the right to derive a transient and directly perceivable representation of conten

46、t within the TVA RMP domain. NOTE: If the device that creates the human perceptible rendition of the content is not a TVA RMP device (e.g. an analogue television set), then this right is not applicable. In that case the appropriate right is required (see Analogue Export, Digital Export SD and Digita

47、l Export HD). Analogue Export “Analogue export“ is the right to create a user accessible analogue signal representing the content as an output, and thus outside of the TVA RMP system. An example of an analogue export would be sending the content over S-Video to a VCR or TV. NOTE: Until such time as

48、there are more display devices that are directly under the control of RMP systems, the broadcaster is encouraged to allow analogue export with appropriate conditions or consumers will be unable to use their legacy analogue systems to create a viewable version of the programme. Digital Export Standar

49、d Definition (SD) “Digital Export Standard Definition“ is the right to create a Standard Definition digital signal representing the content as an output outside of the TVA RMP system. An example of a Digital Export SD would be sending the content over a legacy digital output to a display or recorder with a standard definition digital input. NOTE: If the consumer has digital devices outside the scope of the TVA RMP system, this right with appropriate conditions must be granted for those devices to be able to receive the content.
