An Experiment on Multipoint Tele-immersive Communication with Tiled Display Wall

In remote communication via the Internet, the existence of participant by video streaming of real scene is important. In addition, we consider that non-verbal communication plays an important role in remote communication. In order to realize realistic communication between remote places, the display of video image in remote site with the large-scale screen is effective. However, the video image by wide-area display using a projector and large screen is low-resolution, and sufficient presence is not obtained. In this paper, we have constructed the multipoint tele-immersive communication environment with tiled display wall and have conducted experiment in order to study the possibility of realistic remote communication with video streaming. We have implemented display technology on tiled display wall high-resolution multivideo images which captured by 2 sets of IEEE1394 cameras. By using the technique, we have constructed the system to display on tiled display wall of remote site by transmitting via LAN each video image which captured by multiple cameras set on tiled display wall in 3 remote sites, and have conducted the communication experiment.
