Systems, apparatus and methods provide an automatic capability for generating interactivity event applications for execution on receiver devices within a broadcast network based upon interactivity event application data, information and sequence logic. Interactivity event content providers may provide to a broadcast network interactivity event application data, event metadata information and sequence logic a broadcast network. Interactivity application data for an interactive sequence may be delivered out-of-band, such that the application data is not embedded in an interactivity event. Interactivity sequence application data may be sent out-of-band from the associated interactivity event signaling message. Application data may be sent on a different transport channels in advance of the interactivity event. The system may determine when data should be sent out-of-band and when it should be sent in-band.
