Abstract: An ITV application definition language (ADL) used to generate ITV applications for different types of target platforms and devices. The ADL provides a plurality of core data structure types upon which one or more data structures may be built. Data structures storing ITV content presentation and behavior information are referred to as resources. A resource is associated with a globally unique identifier that allows the data structure to be efficiently stored and retrieved from a hash table. A resource is also associated with an expiration time stamp that indicates when the resource is to be freed from memory. A resource is of arbitrary length, and contains values that differ from the default values stored at a receiving client device. Resources are also packaged into a module that may be catered to a platform and/or profile of a receiving client. The client may quickly determine whether the module is relevant to it by examining the platform and/or profile ID contained in a header of the module.

Abstract: A system and method for producing content for episodes of an interactive program that allows content creation during script writing and editing, film editing, after film editing, and in live production, and for content production, responsive to inputs from script writing software and non-linear editing software as well as direct user inputs, for storing content, presentation, and behavior information using an XML schema.
