Mobile 3D Video
ÂWith recent advances in capture and display technologies, 3D video communication and entertainment services are expected to become reality and redefine the communication and entertainment services with high immersion. To enable these exciting new services, Joint Video Team (JVT) of ITU-T and MPEG has devoted its recent efforts to extend the widely deployed H.264/AVC standard for multi-view video coding (MVC). MVC provides superior network robustness and compression performance for delivering 3D video by e.g. taking advantage of the inter-view dependencies of the different visual channels. In addition, its backwards compatibility with H.264/AVC codecs makes it widely interoperable in environments having both 2D and 3D capable devices.
Nokia's MVC SoftwareNokia Research Center has developed a highly optimized MVC decoder running on Maemo platform, and demonstrated a natural real-time 3D movie playback on a modified Nokia N800 internet tablet with an integrated auto-stereoscopic display. The prototype was showcased at IEEE 3DTV-CON and Nokia World 2008.Â The source code implementing the 3D Video playback demos mentioned above is available for download now. The Nokiaâs MVC software includes two modules:
1. MVC Encoder, which runs in PC and configured to generate MVC compliant bitstreams
2. MVC Decoder is a player, fully optimized for the Maemo platform, and decodes stereoscopic MVC bitstreams.
