Three-dimensional TV is expected to be the next revolution in the history of television. It has only recently become feasible to deal with the high processing and bandwidth requirements for real-time acquisition, transmission, and display of high-resolution 3D TV content. We have built a complete end-to-end 3D TV system. Our system performs real-time acquisition, transmission, and 3D display of dynamic scenes.

Background & Objective: Our system uses existing broadband protocols and compression standards for immediate, real-world 3D TV experiments and market studies. This system can plug into today's digital TV broadcast infrastructure and co-exist in perfect harmony with regular TV. Today, digital broadcast networks carry hundreds of channels and presumably a thousand or more channels after the introduction of MPEG-4. This makes it plausible that a number of them will be dedicated to 3D TV. Similar to HDTV, the introduction of 3D TV can proceed gradually, with one 3D channel at first and more to follow, depending on market demand. Furthermore, our system demonstrates that 3D TV offers a richer, more immersive experience than regular TV. It increases entertainment value and realism without the encumbrance of special glasses.

Technical Discussion: In our system image acquisition consists of an array of hardware-synchronized cameras that capture multiple views of the scene. In order to deal with the high processing and bandwidth requirements, the system uses a fully distributed architecture with clusters of PCs. A multi-projector 3D display with horizontal parallax achieves large, high-resolution output images. The system is scalable in the number of acquired, transmitted, and displayed realtime video streams.

Collaboration: Microlens Technologies, North Carolina, USA.

Future Direction: Improved 3D display, multi-view video coding, computational improvement of the displayed video.
