I want to play stereoscopic hdtv(the resolution is 1920*1080) video through pc and two projectors. How to configure my computer? I think hardware decoder will be better(for example the nvidia fx4000 graphic card). Can someone give some suggestions? Thanks. | ||

The only one software existing in the world able to do this is DepthQ Server code. See following link for details: http://www.depthq.com/depthqserver.html We had already delivered the configuration requested by you to several companies like IMAX, Disney, Simex or NHK Japan. I lead the team of people working on DepthQ Server development - so E-mail me directly if you have any questions. If you are located in Europe, my company GALI-3D (http://www.gali-3d.com) can take care about the software (and preferably fine tooned compatible HW) delivery. Michal | ||

Well, it is possible to play 2*1080p on any high-end machine. On my 3 GHz Pentium D, I can even play 3 1080p files encoded in Windows Media simultaneously. You just have to encode your stereo video in side-by-side or over/under format and play it in Windows Media Player. If you have set your desktop to horizontal or vertical span mode (1920 x 1080 pixel resolution per screen), the left view will appear on the first VGA/DVI output and the right view on the second one. It is important that you use the span mode feature of the NVIDIA graphics driver, not the feature in the Windows display properties dialog, else one screen will stay black. If you want to use a special 3D video player instead of the simple Media Player solution, you can try Stereoscopic Player. Its dual screen output viewing method works on any graphics card (View->Viewing Method->Dual Screen Output). You can download it from http://mitglied.lycos.de/stereo3d. Not all video codecs support resolutions beyond 1920 x 1080 pixels. For example Xvid does, DivX does not. The Windows Media decoder is restricted to 2000 x 2000 pixel, at least on Windows XP. On Windows Vista beta 1 there is no restriction. The advantage of the Windows Media codec over Xvid: It is able to use both cores of a dual core CPU, which is absolutely necessary if you want to play 2 * 1920 * 1080 without dropped frames. If you have not bought the hardware yet, make sure to buy a dual core CPU, I suggest at least 3 GHz, and fast dual channel memory (I use DDR2 667 MHz). The graphics card should use PCIe, not AGP. | ||

Anyone know whats the quality difference and/or the standard that HD video needs to be encoded at? I mean what bitrate is used for actually encoding in WMVHD? and is this compression rate equal to the "so called standard" that digital cinema is using such as jpeg 2000? Is there any one bitrate compression from WMV or MPEG2 that is a standard for HDTV? Regards Clyde | ||

Clyde: The best method how to measure video quality, is so coled PSNR (peak signal to noise ratio) calculation. This will give you in dB the diference betwen original movie and the compresed one. Difference less then 1-3 dB is usualy invisible. The HDTV video system usualy store non-compresed data - so the PSNR could be directly measured ... From this point of view the prioprietary mutlti CPU optimized coding alogorithm used in DepthQ Server gives at least identical results as JPEG2000 (at 8 bit color quality) and overperforms totaly Windows Media Codec. According bitrate - this is not so much important information when the target is high quality playback. The key information is playabaility and quality, not file size. The digital cinema standards use 12 bit color coding - so it is in priciple impossible to get such data from PC becouse all PC HW has 8 bit color coding. This will need diferent standard for PC graphic card output specification. If you realy need 12 bit output you can pay $20 000 for CyViz cinema video server (for stereo you will need optimaly 2 one and synchronziation HW). | ||

Digital cinema uses JPEG2000 at up to 250 Mbps. For WMV, Xvid, H.264, you need about 10-15 Mbps for good quality at 1080p resolution. For MPEG-2, it's 25 Mbps. | ||

Thanks. But how to compress a 1920*2160 video stream file? Which codec is better? Most of the codecs donnot support above 20Mbps. | ||

hahaha: If you need this for a comercial project and you have money for this project our DQ3D codec is the answer (works up to 4096x4096 with 500 Mbs data flows). Contact LightspeedDeesign or me for availability. | ||

Try going to www.videohelp.com... Question is more appropriate, better answered there. |
