Tele-immersive Communication Research Articles

In order to support advanced remote collaborative works via WAN, sharing various visual contents between remote sites and displaying the existence of remote participants by transmission of high-quality video streaming in real scene is important. However, the display specification of large-scale screen system such as commercial projector and wide-area monitor to display these visual contents is low-resolution, and displaying of real video streaming with sufficient quality is difficult. In this paper, we have constructed tele-immersive environment with tiled display wall to realize displaying real video streaming and visual contents by high-resolution. In addition, we have tried the construction of the environment to display more high-quality video streaming on tiled display wall by transmitting multi-video streaming which captured by two cameras in remote site. By using the environment, we have conducted some experiments on tele-immersive communication on JGN2plus network which is a nationwide scale WAN. From experimental results, we have showed that these video streaming have been displayed wide area of remote site more high-quality than magnified view of video by a single small camera. Moreover, we have tried realistic display processing of ultra resolution astronomical observation image and movie data to display in full view visualization contents with ultra resolution which is difficult to display on a usual PC. As these results, we have enabled to observe the entire image of observation data all over tiled display wall.
