ETSI - TS 102 822-3-4
Broadcast and On-line Services: Search, select, and rightful use of content on personal storage systems ("TV-Anytime"); Part 3: Metadata; Sub-part 4: Phase 2 - Interstitial metadata
|Publication Date:||1 December 2012|
The present document is one in a series of Technical Specification documents produced by the TV-Anytime Forum. These documents establish the fundamental specifications 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.
TS 102 822-1  and TS 102 822-2  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 environment. TS 102 822-1  provides benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the specifications enable key business applications. TS 102 822-2  presents the TV-Anytime System Architecture and the relationship between Phase 1 and Phase 2 technologies. These first two documents are largely informative, while the remainder of the series is normative.
The Phase 2 TV-Anytime Metadata schema is a
The present document has been developed during the second phase of TV-Anytime and deals with the metadata necessary to enable interstitial replacement, within a PDR device.
The set of metadata described in the present document was selected in order to satisfy the usage scenarios listed in TS 102 822-1 . The formal definitions of metadata schemas should be read in conjunction with the system specification (TS 102 822-2 ) defining how they could be used in an end-to-end system.
TV-Anytime only defines the format for metadata that may be exchanged between various entities such as between content providers and consumers, among consumers, or between a third-party metadata provider and consumers.
XML is the "representation format" used to define schemas in TV-Anytime specifications. 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.
