Automated archive of the lectures by MPEG2 over intranetwork in Hiroshima University

On April 2002, we have established the automated electronic archive of two-way TV lecture system at Hiroshima University and archived 600 lectures in 4Mbps MPEG2 format and 1Mbps MPEG4 format. Also we have archived 50 conventional one-room lectures and special discourse taken by DV cameras. The two-way TV lecture is typical example of hi-cost and hi-quality resource, and DV shooting of conventional lectures is the counterpoint. We compare them as e-learning resource.
