    Abstract
    UNESCO and OECD emphasized educational equality considering the correlation between income level and education. ICT is important to improve the equality. There are two types of ICT application in the field of education; virtual university activity and collaboration system. We can see many virtual university activities and they take server-client configurations. Educational contents are provided by an education center and other sites receive them. Collaboration is even important in the competitive world. EU also included distributed collaboration environment as one of the research target in FP7 (EU 7th Framework Program). By collaboration, under-subscribed class can be held as a joint class and lack of strength in each institution can be covered by faculties in other institution. Collaboration is also useful because interaction among students beneficial. In collaboration system each site will act both as a server and as a client with regard to the educational service and information. Therefore, the collaboration system model takes P-2-P model. Every station has equally transmission and chairmanship functions. And the control of each transmission is important as a total system.
    NIME has built up an inter-university collaboration network, SCS, using satellite technologies under the Ministry of Education. SCS provided natural collaboration environment using easy multi-site and multi-channel operation capabilities. It uses two-way 1.5Mbps channels and 150 sites in 120 universities are in the network. All the transmission is controlled by a central station in NIME. The operation started in 1996 and it has been used for a variety of collaboration activities for more than 23,000 hours, 9,800 sessions and 156,000 site*hours. More than half of the sessions were with more than three sites. Half of the sessions were for joint classes. The collaboration activities were almost in all fields from literature, language to physics and mathematics. And the satellite was used more often in the provincial area than the urban area.
    Through various collaboration activities, lessons have been learned among universities. The benefits both to students and professors were pointed out. A classroom of students could join important outside activities and interaction with outside people gave them motivation to study further. While basic physical classroom design is important, of course, more important is the pedagogical class design. Valuable experiences were shared through the activities. SCS has effectively contributed to the improvement of education. This presentation discusses the importance of the collaboration system and reviews the actual operational results through more than 10 years.
