Experiment on Multi-video Transmission with Multipoint Tiled Display Wall

In order to realize realistic remote communication between multipoint remote places via the Internet, the display of video streaming in each remote site with the large-scale screen is effective. However, grainy video is displayed on largescale screen to depend on the display resolution specification of display equipments such as a projector and wide-area monitor, and sufficient quality is not obtained. In this paper, we have constructed remote communication environment with tiled display wall in multipoint sites and have conducted experiment in order to study the possibility of realistic remote communication with multi-video streaming. From experimental results, these video streaming from each site have been shown to display more high-quality than expanded video image by single small camera. Moreover, we have measured the network throughput performance for each transmitted and received video streaming in this environment. From measurement results, the steady throughput performance has been gained in the case of each transmitted and received video streaming.
