Fundamental Experiment on Multi-video Communication in Multipoint Tiled Display Environment

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. we have constructed the multipoint tele-immersive communication environment with tiled display wall, and have conducted fundamental experiment to display high-resolution video image on tiled display wall by transmitting each video image which captured by multiple cameras in order to study the possibility of realistic remote communication in multipoint sites. From the result, these video images have been shown to display more high-quality than expanded video image by single small camera.
