摘要

本文介绍了一种利用千兆以太网全向摄像系统和灵活的中间件系统实现实时、双向视频传输的新型远程会议系统。与传统的单向摄像机相比，全向图像具有更大的优势，可以提供比单向摄像机更宽的视野，甚至可以在远程分隔的小房间之间实现灵活的远程会议。精确描述了采用WMV格式的高清全方位视频控制中间件的系统架构和功能，以及有效的视频传输系统[4]。引入QoS控制功能，根据网络和CPU负载的变化动态控制视频的帧率。构建了一个远程医疗会议的原型系统，应用于远程医疗教育，并对我们提出的高清全方位视频系统的性能进行了评估。通过对原型系统的性能评估，验证了系统的有效性。

A New Teleconference System for Healthcare Applications by GigaEther-based Omni-directional Video Transmission

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 [4] 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.
