The digital set-top box as a virtual channel provider

Abstract. This research is based on the realization that the desktop computing paradigm is not appropriate for television, because it is adapted to fundamentally different user aspirations and activities. Instead, the virtual channel is a model that aids the organization and dynamic presentation of digital television programming from a combination of live broadcasts, prerecorded content and Internet resources at each set-top box. The goal is to design the respective framework of user interface patterns that consider the affective nature of television usability and facilitate the diversity of viewing situations.
