The demand for video-based distance conference and distance learning is emerging for universities which have more than one campus or proceed to the interchange of its credits with other universities. However, as the Internet does not guarantee the QoS(Quality of Service), packet losses may occur even if there is enough bandwidth. The existing TV conference systems and tools have the problem with respect to the robustness against the packet losses. In this paper, we develop a high quality video transmission system with packet loss recovery functionality using FEC to deploy for the inter-university communications via the Internet. We describe not only the theoretical result but also the practical experiments on several networks.
