MediaPublishing is an application project within the BERKOM programme. More and more publications for different target groups are produced on multimedia basis. By using high speed communication networks and standardized protocols, distributed applications and scenarios for planning, editing, production and partially also for usage of multimedia publications became possible. In the realisation and test of such complex, distributed production chains for the development of media in distance teaching lies the goal of the project MediaPublishing. The first course produced with the editorial environments and communication facilities now in progress is "Technical data security in communication networks".
