Televisão digital interativa e o desafio da usabilidade para a comunicação

Abstract

The full implantation of the ISDTV – International System for Digital Television is foreseen to occur in about one decade. Among the features of the model adopted, we point out the terrestrial and opened transmission with resources of mobility, portability and interactivity. The introduction of interactive services creates different modalities in the way of the expended television enjoyment. As well as, it must offer in the first moment difficulties to the majority of the population if it doesn’t present a high level of usage, which is an elementary concept in interactive digital TV and which can reduce the population adaptation time to this new language being settled. Resulting from the convergence among television, computers and telecommunications, the interactive TV must promote the digital inclusion connecting the viewer to the cyberspace. During this process, the usage of the graphical interface plays an important role as facilitator to communication.
