scope:

The present document is part of TV-Anytime Phase 2 that proposes an evolutionary range of features which describe PDR (Personal Digital Recorder) usage models that the TV-Anytime standards facilitate. The TV-Anytime specifications enable search, select, acquire 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 Metadata (TS 102 822-3-1 [3], TS 102 822-3-2 [4], the present document and TS 102 822-3-4 [5]), Content Referencing (TS 102 822-4 [6]), Rights Management (TS 102 822-5-1 [7] and TS 102 822-5-2 [8]), Bi-directional Metadata Delivery (TS 102 822-6-1 [9], TS 102 822-6-2 [10] and TS 102 822-6-3 [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 document addresses more specifically the Phase 2 extended metadata features of the TV-Anytime specification as identified in TS 102 822-1 [1].

Metadata is generally defined as "data about data". Within the TV-Anytime environment, the most visible parts of metadata are the attractors/descriptors or hyperlinks used in Electronic Programme Guides, or in Web pages. This is the information that the consumer or agent will use to decide whether or not to acquire a particular piece of content. The TV-Anytime metadata system allows the consumer to find, navigate and manage content from a variety of internal and external sources including, for example, enhanced broadcast, interactive TV, Internet and local storage. It defines a standard way to describe device profiles, consumer preferences to facilitate automatic filtering and acquisition of content by agents on behalf of the consumer. Consumers, as used in the present document, include educators and students, who may use selected programme segments in the classroom or laboratory.

There is a need to associate metadata with content to facilitate human and automated searching for content of interest. Such metadata includes descriptive elements and attractors to aid the search process as well as elements essential to the acquisition, capture and presentation processes; content rights, formats, duration, etc. Many of these descriptive elements can be found in EPGs and HTML documents.

The process of creation and evolution of metadata for an individual content item may involve many organizations during the course of creation, distribution and delivery to the consumer. Thus, there is a clear need to define a common metadata framework and a standard set of metadata elements in order to ensure a high level of interoperability within the chain from content creation to content delivery.

TV-Anytime Phase 2 extends the definition of TV-Anytime Phase 1 metadata to cover descriptive data about content, such as content title and synopsis, but also data about how the content should be consumed. Such metadata is called "attractors" because they can attract a consumer to content. Attractors allow consumers to find, navigate and manage content from various sources. New Phase 2 attractors include:

• Content Packaging.

• Targeting metadata.

• Device Capabilities.

• Interstitial Content.

• New Content Type.

The formal definitions of metadata schemas should be read in conjunction with the system specification 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.

XML [15] is the "representation format" used to define the schemas of the TV-Anytime Metadata Specification. Although XML Schema is used to define how metadata is represented in XML, it can also be used to describe equivalent, non-XML representations of the same metadata.
