Abstract: A system for allowing media content to be used as an interactive media program comprises: (a) media content in the form of successive image display frames indexed in a time sequence; (b) object mapping data specifying the locations of objects appearing in the display of media content which are to be rendered interactive; (c) linkages provided through an associated interactive media program from the objects specified by the object mapping data to interactive functions to be performed upon selection of the objects in the display; and (d) a user system for operating the interactive media program in conjunction with the display of the media content by selecting an object appearing in an image display frame and performing the interactive function linked thereto. The invention includes an authoring system for generating the object mapping data for the media content.
