3dtv.at Stereoscopic Player and Stereoscopic Multiplexer S3D-Today November 2006 Munich, Germany

Peter Wimmer - 3dtv.at2 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.at3 About 3dtv.at  Focus  Stereoscopic video playback  Stereoscopic video recording  Products  Stereoscopic Player  Stereoscopic Multiplexer  Location  Linz, Austria   Timeline  Development started 2001  Completed diploma thesis in June 2004  Company founded in 2005

Peter Wimmer - 3dtv.at4 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.at5 Real-time Format Conversion  Real-time format conversion …  … avoids vast number of files  … requires full color left and right views  … gives best quality  Suitable source formats Over/Under Side-by-Side Interlaced (Field Sequential) LR L R L R Dual Files

Peter Wimmer - 3dtv.at6 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.at7 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.at8 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.at9 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.at10 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 Video Section ROM Section

Peter Wimmer - 3dtv.at11 Stereoscopic Player Viewing Methods Anaglyphs Shutter glasses Polarized projection Native support Any graphics card, any display Software pageflipping (ATI and Intel) NVIDIA stereo driver / OpenGL Native dual screen output support NVIDIA stereo driver / OpenGL And many more…

Peter Wimmer - 3dtv.at12 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.at13 NVIDIA Stereo Driver Configuration  Stereo driver  Install NVIDIA consumer stereo driver  Version number of graphics and stereo driver must match  Configure and activate the stereo driver  Stereoscopic Player  Select ‘NVIDIA Stereo Driver’ viewing method

Peter Wimmer - 3dtv.at14 Pageflipping via Stereo Driver

Peter Wimmer - 3dtv.at15 Native Dual Screen Output 1.2.

Peter Wimmer - 3dtv.at16 Dual Screen Output via Stereo Driver  Graphics driver set to clone mode  Normal 2D operation possible

Peter Wimmer - 3dtv.at17 Stereoscopic Player Features  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

Peter Wimmer - 3dtv.at18 Stereoscopic Multiplexer Concept Right streamLeft stream RL Combined video stream RL

Peter Wimmer - 3dtv.at19 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.at20 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
