The possibility of convergence of interactive digital television to other devices enables various usage scenarios. Such scenarios must be studied to assess their viability. This paper aims to present the use of pre-patterns in specification of scenarios of converged applications for interactive digital television in order to validate the usage scenarios and to define their interaction design.

The possibility of convergence of iDTV to other devices enables various usage scenarios, for example: “If a user interacting with the iDTV has to leave from home, she can continue to interact with content from the web or her mobile device.” In this work, usage scenarios of applications of convergence of media with characteristics of cross-media [6] are called converged scenarios. Cross- media refers to the use of multiple devices seamlessly. The specification of converged scenarios must to describe the user's access to the various forms of contents that will be delivered in the most appropriate device in a specific contextual situation and according to her needs.
