The recent advances in capture, display and content representation technologies allow 3D video services to come to reality. In this paper, we present a prototype device that implements the emerging MVC standard on a portable device and achieves real-time 3D video operation. The developed prototype is based on Nokia N800 Internet Tablet and it is able to decode and display stereoscopic video simultaneously. To achieve this, an H.264/AVC decoder is first ported on the N800 environment with various optimizations and architectural changes, so that real-time decoding operation of two views is possible. The decoded pictures from different views are then interleaved and rendered on a screen with a parallax barrier. This way, the user is able to enjoy 3D video real-time on a mobile device. It is believed that this implementation is a realistic demonstration of the potential of upcoming mobile 3D video services, such as mobile 3DTV, mobile 3D video conferencing, etc.
