ABSTRACT
In this paper, the accessibility of the interactive television is being discussed seen as a primary factor for its satisfactory adoption and commercial success. This is a presentation of work undertaken in the context of a research project aiming at delivering iTV services to disabled children. The project approaches this objective through the utilization of the upcoming MPEG-21 ISO standard. Based on that, iTV accessibility is faced through metadata and adaptation. This work approaches the accessibility of iTV in a wider manner contrary to previous studies that focus mostly onto the users with low vision. Such a case study is being presented accompanied with a discussion of relevant architectures, technologies and faced design issues.
