Abstract:
User interactions with an interactive media program are defined by an interaction document, such as a SMIL document, that may be downloaded by a user before playing or viewing of the associated media program. In the case of live events that are recorded by the user for later viewing, the interactions that may have taken place during the original scheduled broadcast of the event may no longer be valid. In this case, a method and apparatus is provided to allow the user downloading an interaction document for a media program to receive updated versions of the interaction document that can be used when viewing a recording of the media program. In one exemplary embodiment, the media playback system sends a request for an interaction document to an interaction document server responsive to the recording of the interactive media program. The interaction document server may send the updated interaction document to the media playback system responsive to the request if one is available.
