Collaborative t-learning: bringing greater levels of interactivity into the home

T-learning - the provision of educational services over interactive digital TV - is emerging as a important medium to create opportunities for learning at home. In this paper, we elaborate on a framework for the development and deployment of collaborative t-learning services, presenting an architecture that allows distributing the logic of a service, a way to define complex interaction patterns among users and a network infrastructure that provides adequate support for the communication needs.
