Accessible interactive television using the MPEG-21 standard

Abstract

In this paper, the accessibility of interactive television (iTV) is discussed as a primary factor for its satisfactory adoption and commercial success. The work presented here is undertaken in the context of a research project that focuses on delivering iTV services to disabled children. This objective is accomplished through the utilization of the arising MPEG-21 standard. Based on that standard, iTV accessibility is investigated in terms of metadata and content adaptation. The novelty of the contribution lies on a systematic methodology that deals with a wide range of accessibility problems, as opposed to previous studies that focus mostly on users with only one specific disability.

Investigating pay-as-you-go to address issues of trust, privacy and security around media use at home

“…They also investigated the use of a fingerprint reader instead of the conventional alphanumeric code as a new means of accessing profiles and increasing security, which according to [35] was perceived positively by families for the most part. In addition to the aforementioned studies, Vlachogiannis et al [37] have also investigated the use of profiling for iTV using the MPEG-21 standard and Luyten et al [38] have made use of profiles in their Telebudies social TV system. Another ethnographic study [41] found that security concerns varied enormously from household to household, with those that contained adults alone wanting something to prevent intruders from gaining access to the system from their home.…”
