Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers.

ETSI ETSI TS 102 822-6-2 V1.3.1 (2006-01) 5 Introduction “TV-Anytime“ (TVA) is a synchro
23、nized set of specifications established by the TV-Anytime Forum. TVA 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. TS 102 822-1 2 and TS 102 822-2 3 set the context and system ar
24、chitecture in which the standards for Metadata, Content referencing, Bi-directional metadata and Metadata protection are to be implemented in the TV-Anytime environment. TS 102 822-1 2 provides benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the
25、 specification enable key business applications. TS 102 822-2 3 presents the TV-Anytime System Architecture. These two documents are placed ahead of the others for their obvious introductory value. Note that these first two documents are largely informative, while the remainder of the series is norm
26、ative. The features are supported and enabled by the specifications for Metadata (TS 102 822-3 sub-parts 1 4, 2 5, 3 6 and 4 7), Content Referencing (TS 102 822-4 8), Rights Management (TS 102 822-5 sub-parts 1 9 and 2 10), Bi-directional Metadata Delivery (TS 102 822-6 sub-parts 1 11, 2 (the presen
27、t document) and 3 12) and Protection (TS 102 822-7 13), Interchange Data Format (TS 102 822-8 14) and Remote Programming (TS 102 822-9 15). This list of features is to be used as guidance to manufacturers, service providers and content providers regarding the implementation of the Phase 1 and Phase
28、2 TV-Anytime specifications. ETSI ETSI TS 102 822-6-2 V1.3.1 (2006-01) 6 1 Scope The present document is the sixth in a series of specification documents produced by the TV-Anytime Forum. These documents establish the fundamental specifications for the services, systems and devices that will conform
29、 to the TV-Anytime standard, to a level of detail that is implementable for compliant products and services. Congruent with the structure initially defined by TV-Anytime, these specifications are parsed into three major areas: Metadata, Content Referencing, and Rights Management and Protection. With
30、in these general areas, the following specifications have been developed : TS 102 822-3-1 4, TS 102 822-3-2 5, TS 102 822-3-3 6, TS 102 822-3-4 7 TS 102 822-4 8, TS 102 822-5-1 9, TS 102 822-5-2 10, TS 102 822-6-1 11, TS 102 822-6-2 (the present document), TS 102 822-6-3 12, TS 102 822-7 13, TS 102
31、822-8 14 and TS 102 822-9 15. TS 102 822-1 2, TS 102 822-2 3 define the context and system architecture in which these specification shall be implemented. TS 102 822-1 2 provides benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the specification
32、enable key business applications. TS 102 822-2 3 presents the TV-Anytime System Architecture. These two documents are largely informative documents, while the others in the series are normative. The scope of the present document comprises the delivery of TV-Anytime metadata and content referencing i
33、nformation via a bi-directional network using a PDRs return path. The requirements for this technology are outlined in TS 102 822-1 2. The following is an overview of the return paths use: “The consumer can get more information about the programme from either the content provider or from a programme
34、 information service offered by a third party. This could include programme specifications (such as source, duration, format, storage location, etc.), programme schedules, commentary, critiques, liner notes from the provider or third parties, etc.“ “A Return Path is a data connection from a consumer
35、s home digital storage system (e.g. PDR) to one or more service providers. The return path gives the consumer access to interactive content, such as the Internet and interactive television. It also allows service providers to access consumer profile/preference information in order to make business d
36、ecisions regarding content that is provided to the consumer.“ The present document describe the mechanism for describing and discovering IP-based web “metadata services“ from which a client shall request metadata from, and submit user-centric data to. The present document does not address the unidir
37、ectional delivery of metadata over IP networks, or the delivery of content over IP networks. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
