VIDEO CONFERENCE SERVER CAPABLE OF PROVIDING VIDEO CONFERENCE BY USING PLURALITY OF TERMINALS FOR VIDEO CONFERENCE, AND METHOD FOR REMOVING AUDIO ECHO THEREFOR

摘要

Provided are a videoconferencing server capable of providing multiscreen videoconferencing by using multiple videoconferencing terminals, and a method therefor. The videoconferencing server of the present disclosure can be implemented in such a manner that multiple conventional videoconferencing terminals (physical terminals) having one or two displays are logically grouped to operate as a “logical terminal” which operates as if it were one videoconferencing point. Through distribution of videos provided to multiple physical terminals constituting a logical terminal, the videoconferencing server can perform processing as if the logical terminal supported a multiscreen, and the videoconferencing server provides an echo cancellation function in the logical terminal.
