NVIDIA Enables PureVideo on GeForce 6 GPUsby Anand Lal Shimpi on December 20, 2004 1:22 PM EST

We'll let you think about that once more.
Eight months have passed since NVIDIA introduced the GeForce 6800 and its Video Processor and today, after eight long months of waiting with no explanation, we can finally take advantage of it. The wait is over, NVIDIA's PureVideo DVD decoder and drivers are publicly available for download. GeForce 6 owners can finally take advantage of the ~20 million transistors set aside for NVIDIA's "Video Processor" through the driver and codec that are being released today.
When NVIDIA first told us about NV40 back in March 2004 they were quite excited about this "Video Processor" they had built into the chip. What we were originally told is that the Video Processor would be a fully programmable video acceleration engine, capable of accelerating both encoding and decoding operations, making HD video encoding and decoding accessible to all users, regardless of system specs. Eight months later, here are the major points of what NVIDIA's Video Processor can do:
1) Hardware acceleration of Windows Media Video 9 and MPEG-2 decode
2) Spatial-Temporal Adaptive Per Pixel De-Interlacing (with 3-2 and 2-2 detection)
3) Everything previous NVIDIA GPUs have been able to do
The feature list isn't as impressive as say full hardware accelerated encoding, but it's still worth a look. Other features such as gamma correction and motion estimation engine are also supported but we won't dive into them as there's not much new to talk about there.
What was once known only as the NV4x Video Processor has now been given the marketing name PureVideo. PureVideo is exclusively available on the GeForce 6 series of GPUs and only the latest GeForce 6 GPUs have a fully functional PureVideo core. The original NV40 and NV45 (GeForce 6800GT/Ultra) do not have functional Windows Media Video 9 decode acceleration, but the rest of the GeForce 6 series are feature complete (GeForce 6800/6600GT/6600/6200).
So after we've hounded NVIDIA for months about PureVideo, we're finally able to test it. But before we can test it, there's a bit of background that has to be taken care of...
