Research and Design of Interactive IPTV based E-Learning System

IPTV based E-Learning is an attractive and promising service for the widespread of TV devices and potential consumers. Especially in rural area in China, it is more useful than traditional web-based learning application for the lack of computers. However, the transition from traditional web-based Learning system to IPTV-based learning is not trivial for the limited input and control capabilities of the devices such as the keyboard and mouse. It is a challenge task to design an IPTV oriented E-Learning system and deliver web-based learning resources to the new IPTV platform. In this paper we study the learning process on IPTV platform and present the design methodology of an interactive IPTV-based E-Learning system. Several critical issues have been investigated carefully. At first a service framework for IPTV based E-Learning service is introduced. The interoperability with other traditional web-based learning system is enabled by the introduction of several interfaces based on Web Services. Then new development methods of IPTV-Oriented learning resources are then proposed. In addition, conversion strategies for traditional web-based learning resources to IPTV platform are also discussed. Thirdly we proposed the design methodologies for the learning interactivity, which is the key feature of IPTV-based application comparing to traditional VOD ones. To evaluate the framework and the methodology that we have proposed, a prototype IPTV-based learning service is developed.
