Three-dimensional TV is expected to be the next revolution in the history of television. We propose a 3D TV system that allows for real-time acquisition, transmission, and 3D display of dynamic scenes. To manage the high demands on computation and bandwidth we use a distributed, scalable architecture. Our system consists of an array of cameras, clusters of network-connected PCs, and a multi-projector 3D display with a lenticular screen. The display provides stereoscopic color images for multiple viewpoints without glasses. Instead of designing perfect display optics, we use cameras for the automatic adjustment of the 3D display. In this paper, we provide a detailed overview of our 3D TV system, including an examination of design choices and tradeoffs. We also introduce the notion of a computational display that uses cameras and processing to provide optical alignment for the display. We present early results and experiences with our prototype. Our system provides real-time end-to-end 3D TV for the very first time in the long history of 3D displays.
