System Model for t-learning Application Based on Home Servers (PDR)

Although there has been considerable development in elearning through the Internet, digital TV also presents an opportunity for learning in the home. With the introduction of interactive digital TV and the TV-Anytime application, the opportunities for learning in the home will grow. As the number of learning materials is growing exponentially, there will be a need to: facilitate searches, selection, acquisition, and use of educational contents gotten through the Internet or traditional TV broadcasting facilitate the sharing and exchange of educational resources enable educational content and learner information to be shared ensure that educational content can be reused. Thus, we should have educational metadata and define a potential scenario by which educational material can be targeted to groups of users based on aggregated profile data at the head-end and/or content can be broadcast and intelligent profiling agents at the (PDR) level capture and store content of specific interest to individual users. The term "t-learning" has been taken as meaning TVbased interactive learning . In other words, t-learning is an interactive digital TV means for increasing learning opportunities in the home. Although the phrase "elearning" is used for learning via the Internet using a personal computer, with the convergence of the Internet and traditional broadcasting in the form of home server technology, t-learning will be a subset of e-learning and we can consider that t-learning refers to the offering of elearning services using digital TV technologies. Moreover, tlearning's objective is to create digital TV metadata for educational purposes.
