ETSI TS 102 822-3-1

ETSI TS 102 822-3-1 is one in a series of Technical Specifications 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.

As is common practice in such standardization efforts, these specifications were preceded by requirements documents which define 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-Anytime 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 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 normative.

Although each in the series of documents is intended to stand alone, a complete and coherent sense of the TV-Anytime system 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].
