Coding Approaches for End-to-End 3D TV Systems
(Citeseer: Picture Coding Symposium, 2004.)
We present a 3D TV prototype system with real-time acquisition, transmission and auto-stereoscopic display of dynamic scenes. Our system uses a distributed, scalable architecture to manage the high computation and bandwidth demands. It consists of an array of cameras, clusters of network-connected PCs, and a multi-projector 3D display. The 3D display shows high-resolution (1024x768) stereoscopic color images for multiple viewpoints without special glasses. We implemented systems with rear-projection and front-projection lenticular screens. In this paper, we provide an overview of our 3D TV system, including an examination of design choices and tradeoffs. We also discuss potential coding approaches for multiple view video, such as simulcasting, spatio-temporal encoding and sampling-based methods.
