Multiple-angle 3D video technology for distant live concerts

摘要

We are developing a multiple-angle 3D-video system that will allow an audience to enjoy a concert in real time at a distant location by simultaneously shooting multiple stereoscopic images from different angles and transmitting them through a high-speed network. At the receiving side, a decoder restores the original image signals from the received data, and different video images are shown on multiple stereoscopic displays. As a result, the audience can enjoy multiple images of a concert at the same time. The purpose of this system is to give a remote audience the opportunity to enjoy a live concert as though they were at the concert site. This paper examines the technical requirements for the camera arrangement and the transmission rate needed to transmit images of a musical performance with this system. We have built an experimental system with four stereo cameras, and have experimentally transmitted musical performance images to test the system performance. In this paper, we also propose a method for transmitting multiple camera images more efficiently..
