Video communication system using a repeater to communicate to a plurality of terminals

摘要

A video communication system includes a terminal unit for transmitting/receiving an information signal including video information, and a repeater to which a plurality of terminal units identical to the terminal unit can be connected. The repeater forms a transmission signal to be sent to a transmission line by frequency-multiplexing information signals respectively transmitted from the plurality of connected terminal units. The repeater also receives a transmission signal supplied from the transmission line and supplies a plurality of information signals frequency-multiplexed with the input transmission signal to a corresponding terminal unit. With this arrangement, an inexpensive, easy-to-use video communication system which suffers little deterioration in image quality and sound quality can be provided.
