This paper reports trials to record all possible lectures and to deliver on demand the recorded video contents in the Department of Information Systems at Tottori University of Environmental Studies. Main features of the efforts by the department are summarized as follows : (1) Every possible lecture is recorded and delivered on demand. (2) The activity is done at reasonable initial and running costs. (3) Voluntary students and teachers work together as technical and management staff without university staff. For the fiscal years 2004 and 2005, more than 1000 lectures, each of which lasted 90 minutes were recorded successfully, and the total running cost was less than 2-million yen, including the maintenance cost and payment. In this paper, we describe how we realized the three features, and analyze the details of the costs.
