NOTE: 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 Memoran

Introduction The present d
35、ocument is based on a submission by the TV-Anytime forum (http:/tech.ebu.ch/tvanytime). “TV-Anytime“ (TVA) is a full and synchronized 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 p
36、ersonal storage systems from both broadcast and online services. ETSI TS 102 822-1 4 and ETSI TS 102 822-2 5 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 envir
37、onment. ETSI TS 102 822-1 4 provides benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the specification enables key business applications. ETSI TS 102 822-2 5 presents the TV-Anytime System Architecture. These two documents are placed ahead of th
38、e others 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 (ETSI TS 102 822-3-1, ETSI TS 102 822-3-2 6, ETSI TS 102 822-3-3 7 and
39、 ETSI TS 102 822-3-4 8), Content Referencing (ETSI TS 102 822-4 9), Rights Management (ETSI TS 102 822-5-1 10 and ETSI TS 102 822-5-2 11), Bi-directional Metadata Delivery (ETSI TS 102 822-6-1 12, ETSI TS 102 822-6-2 13 and ETSI TS 102 822-6-3 14) and Protection (ETSI TS 102 822-7 15), Interchange D
40、ata Format (ETSI TS 102 822-8 16) and Remote Programming (ETSI TS 102 822-9 17). The present document is to be used by manufacturers, service providers and content providers for the implementation of the Phase 1 features of the TV-Anytime specifications. The present document addresses more specifica
41、lly Phase 1 metadata features of the TV-Anytime specification as identified in ETSI TS 102 822-1 4. ETSI ETSI TS 102 822-3-1 V1.9.2 (2016-03) 10 1 Scope The present document is one in a series of Technical Specifications produced by the TV-Anytime Forum. These documents establish the fundamental spe
42、cifications for the services, systems and devices that will conform to the TV-Anytime standard, to a level of detail that is implementable for compliant products and services. As is common practice in such standardization efforts, these specifications were preceded by requirements documents which de
43、fine the requirements for the TV-Anytime services, systems and devices. ETSI TS 102 822-1 4 and ETSI TS 102 822-2 5 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-Anytim
44、e environment. ETSI TS 102 822-1 4 provides Phase 1 and Phase 2 benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the specification enable key business applications. ETSI TS 102 822-2 5 presents the TV-Anytime System Architecture. These two docume
45、nts 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 normative. Although each in the series of documents is intended to stand alone, a complete and coherent sense of the TV-Anytime s
46、ystem standard can be gathered by reading all of the specification documents in numerical order. The present document deals with Metadata Phase 1 features of the TV-Anytime specification as identified in ETSI TS 102 822-1 4. The term “metadata“ is used to mean descriptive data about content, such as
47、 programme title and synopsis. Such metadata are called “attractors“ because they can attract a consumer to content. Attractors allow consumers to find, navigate and manage content from various sources. In addition to attractors, metadata as defined by TV-Anytime also includes information about user
48、 preferences and history. User preference information, such as favourite actors or TV shows, is included within the scope of TV-Anytime metadata to allow software agents to select content on the consumers behalf. The formal definitions of metadata schemas should be read in conjunction with the syste
49、m specification ETSI TS 102 822-2 5 defining how they could be used in an end-to-end system. TV-Anytime only defines the metadata format for metadata that may be exchanged between various entities such as between the content provider and consumer, among consumers, or between a third-party metadata provider and the consumer. There are two sub-parts to ETSI TS 102 822-3 addressing Phase 1: In sub-part 1, XML is the “representation format“ used to define the schemas of the TV-Anytime Metadata Specification (the present docume
