Approaches to Display of Ultra-resolution Video Streaming by Multi-transmission on Tiled Display Environment

In order to realize advanced remote communication via WAN, we consider that non-verbal communication play an important role, and displaying the existence of participant in remote sites with the large-scale screen by transmission of high-quality video streaming is effective. In past research, we have constructed tele-immersive environment with tiled display wall to realize realistic remote communication. However, the video image captured by a single small camera is difficult to display as video streaming with realistic high-resolution on tiled display wall, because there is a limit in the display resolution of video image captured by a single camera. In this paper, we have constructed the remote communication environment with tiled display wall, and have tried to display ultra resolution video streaming on tiled display wall by transmitting each video image which captured by four cameras in order to study the possibility of realistic remote communication. From experimental results, we could display more high-quality than expanded video image by a single camera. Therefore, we showed to have the feasibility of realistic remote communication by display of ultra-resolution video streaming on tiled display wall by multi-transmission video.
