3dtv.at Introduction to the Stereoscopic Player 3D Korea International Film Festival November 19th, 2011 Gwangju, South Korea
Peter Wimmer - 3dtv.at2 Overview Stereoscopic Player Concept Input settings Output settings Supported formats Features Other 3dtv.at applications Stereoscopic Multiplexer MVC to AVI Converter
Peter Wimmer - 3dtv.at3 About 3dtv.at Focus Stereoscopic video playback Stereoscopic video recording Products Stereoscopic Player Stereoscopic Multiplexer MVC to AVI Converter Location Linz, Austria www.3dtv.at Timeline Development started 2001 Completed diploma thesis in June 2004 Company founded in 2005
Stereoscopic Player The Stereoscopic Player is a 3D video playback application for stereoscopic and multi-view videos on the Windows platform Peter Wimmer - 3dtv.at4
5 3D Video Playback The questions Why do we need 3D playback software? Why not use any 2D video player? The challenges Many 3D display technologies Many 3D formats The solution Real-time format conversion 3D playback software ? !
Peter Wimmer - 3dtv.at6 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/Stream
Peter Wimmer - 3dtv.at7 Dual Files, Dual Streams Dual files Efficient use of multi processor systems Circumvent codec limitations (often limited to 1920 x 1080) 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 Supported for Windows Media, MP4 and AVI formats Multi View Coding (MVC) removes redundancy
Stereoscopic Player Menues Input settings Stored per file Different for each file Output settings Stored globally Configured once Peter Wimmer - 3dtv.at8
9 Format Selection Stereoscopic Player asks the user to select the format when opening a new video Stereoscopic Player remembers settings for each file in the built-in video library
Peter Wimmer - 3dtv.at10 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 (turned off by default) 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.at11 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!
Stereoscopic Player Viewing Methods Peter Wimmer - 3dtv.at12
Peter Wimmer - 3dtv.at13 Stereoscopic Player Viewing Methods Anaglyphs Shutter glasses Polarized projection Native support Any graphics card, any display NVIDIA 3D Vision / Quad Buffered OpenGL Software Pageflipping (ATI and Intel) Dual Screen Output Quad Buffered OpenGL
Peter Wimmer - 3dtv.at14 Native Dual Screen Output 1.2.
Peter Wimmer - 3dtv.at15 Dual Screen Output via OpenGL Requires professional graphics card (Quadro FX, FireGL) Graphics driver set to clone mode Normal 2D operation possible
Peter Wimmer - 3dtv.at16 Stereoscopic Player Viewing Methods HDMI 1.4 frame packing format Via NVIDIA 3D Vision driver Only 24 Hz at 1920 x 1080 Squeezed side-by-side format Squeezed over/under format View|Aspect Ratio|Half Width TVs accept up to 60 Hz View|Aspect Ratio|Half Height Ideal for polarized TVs
Peter Wimmer - 3dtv.at17 Stereoscopic Player Viewing Methods 3D-DLP-TVs LCD displays with micro-polarizer Checkerboard pattern natively support Viewed with shutter glasses Interlaced pattern natively supported Viewed with circular polarized glasses
Autostereoscopic Displays Do not require glasses Two basic technologies Lenticular lenses in front of the LCD panel Parallax barrier behind the LCD panel Lenticular add-on lenses possible Peter Wimmer - 3dtv.at18
Types of Autostereoscopic Displays Narrow viewing angle Only left and right view required Wider viewing angle More than two views needed Image acquisition difficult Interpolation of images planned for future player version Peter Wimmer - 3dtv.at19 Single Viewer Multi Viewer
Peter Wimmer - 3dtv.at20 Stereoscopic Player Viewing Methods Autostereoscopic single-viewer Column Interlaced Tridelity SL Series 3D Display Sharp 3D Displays Generic Single-Viewer Display Autostereoscopic multi-viewer Tridelity MV Series Multi-Viewer Display Generic Multi-Viewer Display More displays are added on request but are already supported by the generic viewing methods
Stereoscopic Player Viewing Methods Peter Wimmer - 3dtv.at21
Peter Wimmer - 3dtv.at22 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 Serial Sony 9-pin protocol Windows Media features Streaming Digital Rights Management Multi-channel audio Multiple audio languages Professional features Customization tool Effect control (COM, UDP, DMX512)
Supported File Formats Video formats Video for Windows (*.avi) Windows Media (*.wmv) Quicktime (*.mov) MPEG-1, MPEG-2 (*.mpg) Material Exchange Format (*.mxf) Third party DirectShow decoders allow playback of additional format Image formats Windows Bitmap (*.bmp) JPEG (*.jpg, *.jps, *.mpo) GIF (*.gif), TIFF (*.tif), PNG (*.png) Peter Wimmer - 3dtv.at23 AVI MPG
3D Blu-ray Playback Stereoscopic Player plays *.ssif files No menu navigation yet (but planned) Third party decryption tool required Peter Wimmer - 3dtv.at24 Install AnyDVD HD Click File|Open File Go to the BDMV\ STREAM\SSIF folder Select largest file
MVC Playback H.264 Multi View Coding (MVC) is the 3D video format of the future MVC is used by 3D Blu-ray disks and the latest 3D camcorders Player supports the MVC codec in *.mts (Sony) and *.mp4 (JVC) files Peter Wimmer - 3dtv.at25
H.264 Multi View Coding MVC is an extension of the proven H.264/AVC industry standard Saves approximately 50% of the right view's data rate Exploits the correlations between the left and right views Peter Wimmer - 3dtv.at26
Effect Control Control curtains, motion seats, lights, fog, water spray, … Supports COM, UDP and DMX512 output Effect data are stored in XML files with *.effx extension Peter Wimmer - 3dtv.at27
Effect Control File Example Peter Wimmer - 3dtv.at28
Peter Wimmer - 3dtv.at29 Stereoscopic Multiplexer Concept Right streamLeft stream RL Combined video stream RL
Peter Wimmer - 3dtv.at30 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.at31 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
