In this paper, a new concept that is Circulation Course Resources (CCR) is introduced, which means the course
resources circulating from the students listening in classroom lecture, camera shooting, video coding, video storage,
video server to the students learning from VOD. The creating course video system and network-teaching system as parts
of CCR architecture are presented separately. To connect the two systems, a middle system defined as Bridge System is
designed and modeled with UML. The core application design of the Bridge System is expressed by the classes design
and main database design. The functions of Bridge System include making the course videos flowing from one system to
another automatically and converting the important data of the two systems into uniform format. The CCR architecture
has been put into action and achieved satisfied results.
