  1. Stereoscopic Player andStereoscopic Multiplexer S3D-Today 27. - 28. November 2006 Munich, Germany

  2. Overview • Part 1 – Stereoscopic Player • 3D playback on PCs • Encoding 3D movies • Stereoscopic Player features • Part 2 – Stereoscopic Multiplexer • Stereoscopic Multiplexer concepts • Fields of application Peter Wimmer - 3dtv.at

  3. Focus Stereoscopic video playback Stereoscopic video recording Products Stereoscopic Player Stereoscopic Multiplexer Location Linz, Austria www.3dtv.at Timeline Development started 2001 Completed diploma thesis in June 2004 Company founded in 2005 About 3dtv.at Peter Wimmer - 3dtv.at

  4. 3D Video Playback ? • The questions • Why do we need 3D playback software? • Why not use any 2D video player? • The challenges • There are many 3D viewing methods • Different resolutions are required to accommodate to hardware performance • The solution • Real-time format conversion • 3D playback software !  Peter Wimmer - 3dtv.at

  5. Real-time Format Conversion L R • Real-time format conversion … • … avoids vast number of files • … requires full color left and right views • … gives best quality • Suitable source formats Interlaced (Field Sequential) L L R R Side-by-Side Over/Under Dual Files Peter Wimmer - 3dtv.at

  6. Dual Files, Dual Streams • Dual files • Efficient use of multi processor systems • Circumvent codec limitations • Playback synchronization is prone to errors • Performance problems when located on same media • Dual streams • Avoid performance problem of separate files • 2D video players show the left video stream only • Only available for Windows Media format Peter Wimmer - 3dtv.at

  7. Format Selection • Stereoscopic Player asks for the format when opening a new video • Stereoscopic Player remembers settings for each file in the built-in video library Peter Wimmer - 3dtv.at

  8. Stereoscopic Metadata • Fundamental idea • It is hard for users to find out the proper layout • The content creator knows the proper layout • Ship video files + format description (= metadata) • Stereoscopic Player … • … reads embedded metadata in Windows Media files • … reads metadata file in same folder as the video file • … contacts metadata server • The official metadata server is maintained by 3dtv.at and provides settings for most commercial 3D-DVDs and some popular video files. Peter Wimmer - 3dtv.at

  9. Creating Stereoscopic Metadata • Use the Windows Media Stereo Attribute Editor to embed metadata in Windows Media files (available for download on the 3dtv.at website) • Click File > Export in Stereoscopic Player to create a separate metadata file (for all other formats than Windows Media)  Improve user experience – deliver your movies with metadata! Peter Wimmer - 3dtv.at

  10. Creating a 3D-DVD • Side-by-side or over/under file • 2x PAL/NTSC resolution or better • Embedded metadata or stereoscopic metafile • Field-sequential version for legacy 3D system • 50/60 Hz TVs + shutter glasses • Hardware demultiplexer + two projectors • Anaglyph version • No stereo hardware required • Limited color reproduction • 4:2:0 color subsampling reduces quality ROM Section Video Section Peter Wimmer - 3dtv.at

  11. Stereoscopic Player Viewing Methods Anaglyphs Native support Any graphics card, any display Shutter glasses Software pageflipping (ATI and Intel)NVIDIA stereo driver / OpenGL Polarized projection Native dual screen output supportNVIDIA stereo driver / OpenGL And many more… Peter Wimmer - 3dtv.at

  12. Stereoscopic Player Viewing Methods • Autostereoscopic displays (dual view) • Native support for horizontally interlaced output • Native support for Sharp 3D displays • Autostereoscopic displays (multi view) • More than two views are required • Image acquisition difficult • Interpolation of images is CPU-intensive and not perfect • Not supported in Stereoscopic Player yet Peter Wimmer - 3dtv.at

  13. NVIDIA Stereo Driver Configuration • Stereo driver • Install NVIDIA consumerstereo driver • Version number ofgraphics and stereodriver must match • Configure and activatethe stereo driver • Stereoscopic Player • Select ‘NVIDIA Stereo Driver’ viewing method Peter Wimmer - 3dtv.at

  14. Pageflipping via Stereo Driver Peter Wimmer - 3dtv.at

  15. Native Dual Screen Output 1. 2. Peter Wimmer - 3dtv.at

  16. Dual Screen Output via Stereo Driver • Graphics driver set to clone mode • Normal 2D operation possible Peter Wimmer - 3dtv.at

  17. General features File playback 3D-DVD playback Capture device support Intuitive user interface IR remote control support Integration features Command line control OLE Automation Customization tool available Windows Media features Web stream playback Digital Rights Management Multi-channel audio Multiple audio languages Stereoscopic Player Features Peter Wimmer - 3dtv.at

  18. Stereoscopic Multiplexer Concept R L R L Right stream Left stream Combined video stream Peter Wimmer - 3dtv.at

  19. Fields of Applications • Live preview during recording • Stereoscopic Multiplexer loaded in Stereoscopic Player • Live broadcasts • Stereoscopic Multiplexer selected as capture device in Windows Media Encoder, running on the server • Stereoscopic Player running on the client • Watching 3D recording • Transferring left and right tape to hard disk not required • Stereoscopic Multiplexer synchronizes tape drives Peter Wimmer - 3dtv.at

  20. Supported Hardware • Camcorders • DV camcorders • HDV camcorders (next version) • Digital cameras • Industrial Firewire cameras • Industrial USB cameras • Webcams • Others • Analog cameras via frame grabbers • Many other WDM-compatible capture devices Peter Wimmer - 3dtv.at
