A New Teleconference System for Healthcare Applications by GigaEther-based Omni-directional Video Transmission
ABSTRACT In this paper, a new teleconference system by using Gigabit Ethernet based omni-directional camera system and flexible middleware system in realtime and bi-directional video transmission is introduced. The omni-directional image has more advantages than conventional one-directional camera in that it provides a wider view than a single directional camera and able to realize flexible teleconferencing even between remotely separated small rooms. System architecture and functions of the middleware for high-definition omni-directional video control and effective video transmission system using Windows Media Video(WMV) format are precisely described. QoS control function is also introduced to dynamically control the frame rate of video depending on the changes of network and CPU load. The prototype system of a teleconference is constructed to apply for remote healthcare education and evaluate the performance of our suggested high-definition omni-directional video system. Through the performance evaluation of the prototyped system, we could verify the usefulness of our proposed system.

ABSTRACT: Recently, a surveillance system has been widely used for our circumstances for the purpose of observing volcano, tsunami, crime prevention, and so on. However, most of surveillance systems are consisted of handy cameras and mono-directional CCD cameras, and so it is caused "blind spot" on the system. In this paper, Omni-directional lens is introduced for Gigabit Ether Camera, and the Seamless Surveillance Video System with high-speed networks and high-resolution Omni-directional cameras is proposed. The proposed system also has the additional functions such as moving detections, recognitions, and object's tracking. The paper discussed about the implementation and evaluation of the proposed system.Advanced Information Networking and Applications (AINA), 2013 IEEE 27th International Conference on; 01/2013

ABSTRACT: Japan is prone to natural disasters occurring including earthquakes, tsunami, typhoon, heavy rain and snow. A wide range and quick information gathering systems are needed after a disaster has occurred. In addition, wireless networks are very useful at a disaster has occurred. By using wireless networks, we can build a network quickly using moving vehicles. But there is a challenging communication environment in hilly and mountainous areas and after a disaster has occurred where communication is completely disabled. In this paper, we introduce SODiCS (Spatial and Temporal Omni directional Video Distribution and Collection System) for challenged communication environment. Data gathered using Omni directional camera and sensor is transmitted to all of the users through a web application. The user can see the data gathered on GIS map as a web service. We equipped the system with two modes of video distribution functions, Live View mode and Storage View mode. The system configuration and architecture are explained and a prototype system is constructed to evaluate the performance of our system.2014 28th International Conference on Advanced Information Networking and Applications Workshops (WAINA); 05/2014
