An MPEG2 over IP transfer system integrating live distance lecture and on-demand distance learning

In the institutions of higher education, hundreds of intellectual activities, i.e. lectures, are performed everyday. It is very important for such institutions to have a system which can archive these activities as their property efficiently and systematically. However it will not always be the good materials for on-demand distance learning if we record the usual lectures. On the other hand, the live distance lecture has been performed. Although some revisions are required, the archives of live distance lecture is well suited for the materials of on-demand distance learning by nature. In this paper we describe the MPEG2 over IP transfer system which is the key technology to integrate the live distance lecture and on-demand distance learning. And then we describe the live distance lecture archive system operated in Hiroshima University.
