DVB Interactive Application Signalling

Scope

The present document defines a framework for the signalling and carriage of interactive applications or services in broadcast and broadband networks. This framework covers:

• Signalling interactive applications or services in both classical broadcast networks and broadband networks.
• Distributing the files of interactive applications or services through either classical broadcast networks or broadband networks.
• Synchronizing interactive applications or services to video or audio content distributed through classical broadcast networks or broadband networks.
• Referencing video, audio or subtitle content distributed through classical broadcast networks or broadband networks from interactive applications or services.

The present document is independent of any particular technology for interactive applications or services. It is intended to be referenced by organizations defining how interactive applications or services are to be deployed and not used as a stand-alone document in its own right. It is expected that those organizations will make a selection appropriate for their market or deployment from among the functionality defined here. The use of “shall”, “should” and similar terms in the present document is intended to apply only if the particular feature is used and not to imply that the feature itself is mandatory.
