A/105, Interactive Services StandardApproved: 29 October 2015

This standard describes the ATSC Interactive Services Standard (ISS). The Interactive Services system allows the broadcaster to connect broadcast programming with additional services related to that programming. Central to this system are Declarative Objects (DOs) providing the user’s interactive experience. Changes to the life-cycle state of Declarative Objects (for example to launch or kill a DO) can be initiated and changed by both broadcasters and viewers. The system provides for the extension of these services to second screens and provides for delivery of needed resources via the Internet path. (Note: There are no plans at this time to establish an external PDI Question Registry as anticipated in Section 8.7 and Annex E.)
