Rapid advancement of information and communication technologies has introduces various dimension of e-Learning environment such as ubiquitous learning, mobile learning and television learning. These technologies enabled learners to access to learning contents through variety of devices with more flexibility and consistency. In order to accomplish learning under these multiple environments, it is necessary to acquire and process the platform information that contains properties and status of the web-accessing devices. In this study, we introduce the design and implementation of a Platform Analyzer which is essential for learning systems that support multi-platform environment. We also have implemented an interactive DTV-centered multiplatform learning environment framework in combination with PC and PDA. Finally, we showed the potentiality of the multiplatform learning environment with design and adoption of learning scenario and sample contents we made in this study.
