A Learning Oriented Technological Framework for iDTV

This paper proposes an open flexible learning oriented technological framework for interactive digital TV (iDTV). The framework is designed to satisfy the pedagogical requirements and deal with the iDTV capabilities and constraints. The framework includes two main products: the authoring tool, where the course is prepared and the course multimedia player, which is capable of presenting the course in an iDTV environment. The proposed approach has been validated in a simulation and real iDTV set-top box (STB) environment.
