Abstract :
In this paper, a flexible middleware system for omni-directional video transmission for various teleconferencing applications 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 flexible TV conferencing even between remotely separated small rooms. In this paper, we describe system architecture and functions of the middleware for high-definition omni-directional image control and effective video transmission system using DV and HDV (1080i format). The MidField system which we have developed so far is used for video stream transmission over IPv4/IPv6 networks. The prototype system of a TV conference is constructed to evaluate our suggested high-definition omni-directional middleware. Through the functional and performance evaluation of the prototyped system, we could verify the usefulness of our proposed system
