Abstract

Creation of a program with interactive content and time-based media would be improved by having several people working simultaneously on both the interactive content and the time-based media. The range of types of data that can be associated with the time-based media also can include a variety of types of content that enhance the time-based media, including data that is opaque to the editing system. To support editing of such programs, enhanced content may be edited into a program as either a clip or a locator, according to a user'"'"'s selection. The components that represent enhanced content also may be edited in the same way as components that represent time-based media. Enhanced content may be represented by enhancement files that include data defining enhancements. An enhancement includes an identifier of the enhancement within the enhancement file, and a reference to a file defining enhanced content associated with the enhancement. Such enhancement files may be imported into a bin of an editing system to create components that describe the enhanced content referenced by the enhancements. The enhanced content may be modified using native applications for the enhanced content during editing of the program. The components describing the enhanced content in the editing system can be updated using identifiers of the enhanced content that are stored by the components. Enhanced content also may be automatically synchronized with time-based media.
