However, there are problems in not only server and network resources but also human resources if the streaming system which consists of networks and servers is newly constructed for each activity. There is a method of regularly preparing the delivery environment as a technique for reducing a human resource. However, there is a problem of needing a special resource. In this paper, we propose a delivery system that uses a computer system constructed with virtual machine technology as a method of solving these problems. This system achieves the delivery environment in a short amount of time by using the environment used for another usage. It saves human resources though the performance is deteriorated. Its effectiveness was confirmed by an experiment on an actual system based on the proposed method.}, pages = {1229--1238}, title = {仮想計算機技術を利用した映像配信システムの構築}, volume = {49}, year = {2008} }
