scope:

The present document shows the system behaviour of a TV-Anytime broadcast system with an interaction channel used for consumer response. It focuses on the use of the TV-Anytime content reference specification in combination with the TV-Anytime metadata specification in a system context. The present document will show examples of how to use both specifications both from static and dynamic viewpoints, i.e. it will highlight the parties involved in the processes and show the interaction between them. The present document will not show the use of rights management in the system: the TV-Anytime Rights Management specification will be included as soon as it is finalized.

To understand the present document, it is necessary for the reader to understand "TV-Anytime Requirements document R-2: the System Description". Since this specification applies TS 102 822-4 [3] and TS 102 822-3 sub-parts 1 [1] and 2 [2] are recommended reading. Both specifications enable the features in table 1 that will be highlighted in a system context in this document.

The main part of the present document (excluding annex B) is that of a cookbook or white paper to the TS 102 822-4 [3] and TS 102 822-3 sub-parts 1 [1] and 2 [2]. It is an informative specification and has therefore not the intention to mandate certain system implementation solutions. Preferred solutions from a technology standpoint will be indicated to allow implementers to build efficient systems. Normative requirements that follow from writing the present document are inserted in the previously mentioned specifications. However, the TV-Anytime system needs certain capabilities from the underlying delivery system. Annex B, the only mandatory part ofthe present document, lists the requirements on the delivery system.

The present document is the second part of a series of gradually more complete system descriptions, enabling developers to make the most of TV-Anytime tools. Future versions of the present document will show more complete TV-Anytime system behaviour like the use of rights management and protection tools.
