The adoption of the middleware Ginga as standard for interactive digital TV is becoming increasingly established in Brazil and in much of Latin America. However, the possibilities created by the middleware are still not well explored by content producers. Much of the currently interactive applications broadcasted has been restricted to just applications with the additional content with little or no relation with the main audiovisual content. Among other factors, when the author is interested in the design of interactive content from the design stage of audiovisual content, would favor the appearance of truly interactive programs, in which, for example, the viewer could decide the destiny of a particular character or the end of a film according to their preferences. This work presents a tool that allows authors of interactive applications for digital TV to design your application using interactive storyboards. Thus, several alternative interaction and layout can be tested even before the production of all audiovisual content, and much interactivity as the main video content can be thought together. Thereby, much richer interactive programs can be made, in which, for example, the viewer may decide the fate of a specific character or the progress of a movie. Moreover, since all final audiovisual content were produced, it can also be incorporated into the tool in order to make the final adjustment and generate the final application, without any knowledge of programming languages.
