PURPOSE:To obtain the device for using plural video images in common and its method advantageous in cost in which cooperation work is attained by sending plural video images through a 2-way video line and using them in common without use of a multiplexer/demultiplexer. CONSTITUTION:A video insert device 104 of a video communication terminal equipment 101 synthesizes plural video images from a user A entered by video cameras 107,108 into one video image, and the video image is sent/received between the terminal equipment 101 and a video communication terminal equipment 110 of a user B. The video image synthesized by the video insert device 104 and the video image synthesized similarly by a video insert device 113 of the video communication terminal equipment 110 of the user B received through a video line are synthesized by a translucent synthesizer 103 so that both the video images are seen through with each other and the synthesized video image is served to the user in the video communication terminal equipment 101 of the user A. Thus, plural video images are sent/received through a 2-way video line without need of a multiplexer/demultiplexer and the video image is used in common. |
