Abstract

본 발명은 다자간 회의에 참가한 가입자들의 영상을 간축시켜 디스플레이되도록 하는 동영상 회의 장치에 관한 것으로, 이를 해결하기 위하여, 복수개의 단말장치와, 이 단말장치와 상호 연결되는 교환기를 구비하고서 다자간 회의가 가능한 동영상 회의장치에 있어서, 복수개의 비디오 카메라로부터 제공되는 영상신호를 간축하는 간축수단과, 간축수단에 의해서 간축된 영상신호를 부호화하는 부호화수단과, 부호화수단에 의해서 각각 부호화된 영상신호를 복호화하고, 이 복호화된 영상신호를 소정의 크기로 병합함과 아울러 이 병합된 영상신호를 부호화하는 교환기, 교환기로부터 제공되는 병합된 영상신호를 복호화하는 복호화수단, 복호화수단에 의해서 복호화되는 병합된 영상을 디스플레이시키는 디스플레이수단으로 이루어짐으로써, 회의에 참가한 가압자들의 영상을 간축시켜 화면내에 디스플레이할 수 있는 효과가 있다.The present invention relates to a video conferencing device for reducing and displaying a video of subscribers participating in a multi-party conference. In order to solve the problem, a video conference capable of a multi-party conference is provided with a plurality of terminal devices and an exchanger connected to the terminal devices. A conference apparatus comprising: condensing means for condensing video signals provided from a plurality of video cameras, encoding means for encoding a video signal condensed by the condensing means, and decoding video signals encoded by the encoding means, respectively; A switch which merges the decoded video signal into a predetermined size and encodes the merged video signal, decoding means for decoding the merged video signal provided from the exchange, and displaying the merged video decoded by the decoding means. Meeting by means of display means Ganchuk the image of the pusher joined to the effect that can be displayed within the screen.
