Technologies de l'information - Cadre multimédia (MPEG-21) - Partie 15: Rapports d'événements

1.1 General

This part of ISO/IEC 21000 specifies - how to express Event Report Requests (ER-R) that contain information about which Events to report, what information is to be reported and to whom; - how to express Event Reports (ER) which are created by an MPEG-21 Peer in response to an Event Report Request when the conditions specified by an ER-R are met.

Event Reports Requests are used for specifying a set of conditions upon which a Peer will generate an Event Report and send it to a Recipient. Event Report Requests also specify what information is to be included in the resulting Event Report. The scope of Event Reporting is limited to reporting of Events between Peers, and does not include internal reporting of Events within a Peer.

1.2 Organisation of the Document

This part of ISO/IEC 21000 comprises nine clauses. This first clause provides scope and the organisation of the specification. Clauses 2 to 5.3 contain a set of references, terms and definitions and abbreviations.

Clause 6 introduces a high level architecture for Event Reporting, while clauses 7 and 8 specify the syntax and semantics of Event Report Requests, and Event Reports. Clause 9 then specifies the data types that are frequently used throughout this part of ISO/IEC 21000.

Finally, Annex A contains the XML Schema definition for the descriptors defined in clauses 7 and 8 and Annex B and Annex C provide examples of Event Report Requests and Event Reports
