Abstract: A control method that can control an MCU and a video conference terminal using a user terminal, and a video conference system for the control method are proposed. The method of controlling a video conference of the present disclosure includes: a pairing request step in which the user terminal connects to the MCU in a wired or wireless type and then requests pairing with a target video conference terminal to the MCU; a pairing step in which the user terminal forms a control channel between the user terminal and the MCU in accordance with approval of the pairing request by the MCU; and a control step in which the user terminal requests one of control items allowed by the MCU to the MCU after the pairing step.

Abstract: Disclosed are a videoconferencing server capable of providing multiscreen videoconferencing by using multiple videoconferencing terminals, and a camera tracking method therefor. The videoconferencing server of the present invention 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 one videoconferencing point. Through distribution of videos provided to the multiple physical terminals constituting the logical terminal, the videoconferencing server can perform processing as if the logical terminal supports a multiscreen. The videoconferencing server provides a function of recognizing and tracking a target in the middle of speaking in the logical terminal.

Abstract: A videoconferencing server for providing a multi-screen video conference by using multiple videoconferencing terminals and a method thereof. The video conferencing server can logically group a plurality of the existing videoconferencing terminals (physical terminals) each having one or two displays to operate like a logical terminal operating as one videoconferencing point. The video conferencing server may process as if the logical terminal supports multiple screens by transmitting videos to the plurality of physical terminals constituting the logical terminal.

Abstract: 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.
