In this paper, a new TV teleconference with flexible middleware for omni-directional video camera is introduced. The omni-directional image has more advantages in that it provides a wider view than a single directional camera and able to realize TV conferencing even between remotely separated small rooms. In this paper, we describe system architecture and functions of the middleware for omni-directional image control and effective video transmission system. The MidField system which we have developed so far is used for video stream transmission over IP network. The prototype system of a TV conference is constructed to evaluate our suggested omni-directional middleware. Through the functional and performance evaluation of the prototyped system, we could verify the usefulness of our proposed system
