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
