Today, the TVDI (Digital and Interactive Television) promises to be a revolution in the communication resources, as the creation of the first colourful and analogical television sets was some decades ago. A lot of issues have been discussed and researched in this area, but the practical results have been too shy in South America. At the final stage of discussion on TVDI it’s crucial to bring essential and technical aspects in the decision making process. Thus, we approach key points to the future decisions in this article: the impacts of the return channel at the levels of interactive. For that we are based on the final results that were obtained through the development of a pilot program to TVDI. The developed program is focused on the educational context and was created for kids. Our pilot research explores different levels of interactive by using basically resources of interactive that need a return channel and resources that don’t require this infra-structure. Besides, we discuss the aspects that illustrate how technical decision of adopting or not a return channel may have an impact on the options of interactive. On the other hand, it is important to reaffirm that a TVDI program can use different kinds of interactive with different levels. And finally, we’re going to use the pilot program to demonstrate the appliance of the strategic use of different levels of proposed interactive and then we are going to show the obtained results.
