An Experiment on Ultra-resolution Video Transmission with Tiled Display Wall in Wide-Area Network

In order to realize high-realistic sensation tele-communication over wide-area network, we consider that non-verbal communication play an important role, and displaying the existence of participant by high-quality video streaming on large-scale screen system in each remote site is effective. However, the display specification of these systems such as commercial projector and wide-area monitor is low-resolution, and displaying of real video streaming with sufficient quality is difficult. Moreover, displaying video streaming with realistic high-resolution is serious, because there is a limit in the display resolution of video image captured by a single camera. We have constructed the tele-communication environment to display ultra resolution video streaming by multi-transmitting each video image which captured by four cameras with tiled display wall which is a technology to display various high-resolution contents by configuring the large-scale display with two or more LCD panels. In this paper, we have conducted an experiment on ultra-resolution video transmission between remote sites via wide-area network by using this tiled display wall environment in order to examine the feasibility of high-realistic sensation tele-communication, and have reported the experimental results.
