ITU-T J.1010 (09/2016) Introduction Service and content protection realized by conditional access (CA) and digital rights management (DR

18、M) are essential in the rapidly developing area of digital broadcast and broadband, including content, services, networks and customer premises equipment (CPE), to protect business models of content owners, network operators and PayTV operators. While conceptually CA focuses on mechanisms to access

19、protected content distributed by a service provider over a network, DRM originally describes type and extent of the usage rights, according to the subscribers contract. PayTV operators have established digital TV platforms, which implement standards for basic functions, extended with proprietary ele

20、ments. Most CA and DRM systems used for classical digital broadcasting, IPTV or new OTT (over-the-top) services capture consumer premises equipment by binding it with proprietary security related elements. As a result, consumer premises equipment configured for use in network or platform A cannot be

21、 used in network or platform B or vice versa. Thus, the consumer electronics (CE) market for digital TV is still fragmented, as specifications differ not only per country, but also per platform. Detachable CA/DRM modules only offer a partial solution: the modules are again proprietary to the CA/DRM

22、system, they are not cheap either, and they are used primarily for cable or satellite TV and are not usable in modern-type equipment such as tablets due to lack of appropriate physical interfaces. Currently implemented solutions, whether embedded or as detachable hardware, result in “Lock-in“ effect

23、s. This seriously restricts the freedom of many players in digital multimedia content markets. Due to technological advances, innovative, software-based CA/DRM solutions become feasible. Maximizing interoperability while maintaining a high level of security, they promise to meet upcoming demands in

24、the market, allow for new businesses, and broaden consumer choice. It is in consumers interest that they are able to continue using the CPEs they bought e.g., after a move or a change of network provider or even utilize devices for services of different commercial video portals. This can only be ach

25、ieved by interoperability of CPEs regarding CA and DRM, based on an appropriate security architecture. Further fragmentation of the market for CPEs can only be prevented and competition encouraged by ensuring a consumer-friendly and context-sensitive exchangeability of CA and DRM systems. Rec. ITU-T

26、 J.1010 (09/2016) 1 Recommendation ITU-T J.1010 Embedded common interface for exchangeable CA/DRM solutions; Use cases and requirements 1 Scope The object of this Recommendation is a set of basic requirements for an exchangeable, embedded common interface, in order to download any necessary CA/DRM s

27、ystem to CPE. The download process is operated under a trusted environment and enables the consumption of protected content delivered via broadcast and/or broadband connections with various types of terminal equipment in line with the acquired content rights of the end-user. This Recommendation is o

28、ne in a series of Recommendations, specifying the whole ECI eco-system. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated wer

29、e valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommenda

32、sewhere None. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 embedded common interface (ECI): Architecture and system to be specified in the ETSI ISG “Embedded CI“, which allows the development and implementation of software-based swappable ECI client

33、s in customer premises equipment (CPE) and thus provides interoperability of CPE devices with respect to ECI. 3.2.2 embedded common interface client (ECI client): Implementation of a CA/DRM client which is compliant with the planned Embedded CI specifications. Note that it is the software module in

34、a CPE which provides all means to receive, in a protected manner, a consumers entitlements and rights concerning the content that is distributed by a content distributor or operator. It also receives the conditions under which a right or an entitlement can be used by the consumer, and the keys to de

35、crypt the various messages and content. An Embedded CI client may have an associated smart card. 2 Rec. ITU-T J.1010 (09/2016) 3.2.3 embedded common interface (ECI) host: Hardware and software system of a CPE, which covers ECI related functionalities and has interfaces to an ECI Client. Note that th

36、e ECI host is one part of the CPE firmware. 3.2.4 protected content: All kinds of protected media, in particular A/V and associated metadata, delivered to the customer application either via linear or non-linear delivery means. 3.2.5 software container: Set of software interfaces to the host and to

37、the client, which strictly separates the CA/DRM client from the host. The provisioning of the interfaces enables the exchangeability of the CA/DRM clients. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: AES Advanced Encryption Standard CA Conditional

40、h must be strictly followed and from which no deviation is permitted if conformance to this document is to be claimed. The keywords “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus this requirement need not be present to claim conformance. The k

41、eywords “is prohibited from“ indicate a requirement which must be strictly followed and from which no deviation is permitted if conformance to this document is to be claimed. The keywords “can optionally“ indicate an optional requirement which is permissible, without implying any sense of being reco

42、mmended. This term is not intended to imply that the vendors Rec. ITU-T J.1010 (09/2016) 3 implementation must provide the option and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conform

43、ance with the specification. In the body of this document and its annexes, the words shall, shall not, should, and may sometimes appear, in which case they are to be interpreted, respectively, as is required to, is prohibited from, is recommended, and can optionally. The appearance of such phrases o

44、r keywords in an appendix or in material explicitly marked as informative are to be interpreted as having no normative intent. 6 Requirements for exchangeable embedded CA/DRM solutions 6.1 General remarks The Group Specification on ECI basic requirements, as covered by the present Recommendation, is

45、 part of a multi-part deliverable specifying a system architecture for general purpose, software-based, embedded and exchangeable CA/DRM systems which would be the most appropriate and future-proof solution for overcoming market fragmentation and enabling interoperability. Key benefits of the envisa

46、ged approach for content security are: Flexibility and scalability due to software-based implementation. Exchangeability fostering future-proof solution and enabling innovation. Applicability to content distributed via broadcast and broadband, including OTT. Support of multi-screen environment. Stim

47、ulation of the market for platform operators, network/service providers, and consumers by avoiding “Lock-in“. The specification of an open eco-system fostering market development. The ECI system aims at exchangeability of CA and DRM systems in CPEs on all relevant levels and aspects, at lowest possi

48、ble costs for the consumers and at minimal restrictions for CA or DRM vendors to develop their target products for the PayTV market. Therefore, amongst others, the ECI has the following functionalities: A software container for the CA respectively the DRM kernel hereafter called ECI Client with: sta

49、ndardized interfaces to all relevant functionalities of the CPE; a standardized Virtual Machine (VM) to run upon. Support of smartcard-less systems as well as use in smartcard-based systems. Inclusion of a multitude of such software containers in a CPE, each container running on its own instance of the VM. Installation of the ECI Client independently from other CPE software by a secure and standardized loader concept.
