A Candidate Standard is a document that has received significant review within a specialist group. Advancement of a document to Candidate Standard is an explicit call to those outside of the related specialist group for implementation and technical feedback. This is the phase at which the specialist group is responsible for formally acquiring that experience or at least defining the expectations of implementation.
A/105: ATSC Candidate Standard – Interactive Services Standard
24 April 2014
The ATSC 2.0 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. In addition to services already part of traditional terrestrial broadcast television, services described in the present standard include personalization, service usage reporting, receiver access to web-based servers, and support for automatic content recognition.
