A HUB Station to control each VSAT station has been neccessary for usual teleconference system. The load is concentrated to the HUB station while the teleconference is going to perfomed. Moreover, the frequency resource is required corresponding to the number of the VSAT stations. As a teleconference system consist of VSAT stations without HUB station by satellite communiction, we proposed a new system for ecology of frequency source using only one channel. The algorithm controlling this system, which makes it possible to perform teleconference on single channel is discribed. The algorithm includes a part of the idea of the capture effect for satellite link. In additoin, The measurements system to evaluate the BER of transfered digital data of picture and sound when the uttering station changing is occored on this system is also discribed.
