Talk:Nvidia PureVideo
From Wikipedia, the free encyclopedia
[edit] "Certified"?
I don't know if the PureVideo HD capable hardwares are actually "certified" for Blu-ray and HD-DVD playback, but it's a fact that PureVideo HD hardwares does hardware acceleration to videos with the same encoding (MPEG2, MPEG4, VC-1, H.264) as most of the Blu-ray/HD-DVD video streams. Though most of the computers (Pentium 4 class or above) also have the ability to decode video stream smoothly (through CPU) without the assistant of video cards, so is the term confusing? ... Yeah, you're probably right. From a vendor's standpoint, NVidia's product guidelines dictate the minimum feature-set/characteristics for PureVideo-HD label/seal. (For example, Geforce 7600GT or better, HDCP, 256MB video RAM, etc.) But whether Nvidia handles the program with full-blown compliance-testing, or simply 'rubber-stamps' the OEM's submission, I don't know.
...I think a category should be added for "Purevideo software", since that's ANOTHER point of confusion. The add-on Purevideo software is basically just an MPEG-2 video player (since XP doesn't come with an MPEG-2 decoder), with some extra fancy post-processing modes not available to third-party players like PowerDVD, WinDVD, etc. If you're only interested in the hardware-acceleration, then any third-party DVD-player (PowerDVD, WinDVD, Nero Showtime, etc.) is sufficient -- the hardware-decoding is accessed through a public-API called DirectX-VA.
For HD-DVD/Bluray playback, the Purevideo software isn't involved at all (so purchasing it is unnecessary.) WinDVD-HD, PowerDVD_HD, and Nero HD-DVD plugin talk directly to the ATI/NVidia display-driver (using DirectX-VA.)
...I would love to see a video chipset/purevideo version comparison matrix chart. —Preceding unsigned comment added by 72.208.26.142 (talk) 05:22, August 26, 2007 (UTC)
[edit] Fair use rationale for Image:Nvidia purevideo logo.png

I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

This page is extremely windows centric. If this is a windows only product that should be noted in the page. —Preceding unsigned comment added by 74.71.245.199 (talk) 00:21, 6 March 2008 (UTC)
