The application of broadband transmission system has become feasible to any locations by using optical fiber cables in various modes; such as optical fiber running in overhead ground wires in power transmission lines, and overhead or undergraund optical fiber cables running in parallel with power transmission/distribution lines. Advances in such infrastructures have brought about greater needs for video transmission, above all, video information switching and transmission. Although the research and development for broadband ISDN (B-ISDN) is making progress by many organizations, solutions to problems associated with the cost and the application must be sought to satisfy immediate needs. Such an environment called for the development of a video information transmission and switching system as an alternative to the B-ISDN. This paper brings forward a video teleconference system developed in the form of a video switching network system.
