Nvidia's Shows Off Working PureVideo
Nvidia today announced the availability of PureVideo. The technology is designed to accelerate MPEG 2 and high-definition content on computer systems equipped with an Nvidia graphics card carrying a GeForce 6-series processor.
Source: Tom's Hardware GuideThe company has been talking about PureVideo for quite a while now, since the introduction of the GeForce 6800 back in April of this year, to be exact. However the enabling software was missing so far. Now, Nvidia has the driver package in place and promises to take video quality on the PC to the next level.
PureVideo is based on a programmable video processing engine integrated in GeForce 6-series graphics processors. According to Nvidia, the feature "eliminates the need for separate hardware or chipsets and takes the load off the PC's multi-purpose CPU to deliver to consumers, high-quality video playback at resolutions up to 720p and 1080i".
Key features of PureVideo include a dedicated 16-way vector processor that enables HD MPEG2 hardware acceleration while taking processing load off the CPU. The technology also is able to accelerate Microsoft's WMV and HD WMV. PureVideo allows real-time video recording, spatial and temporal adaptive de-interlacing from satellite, cable and DVD feeds, 3:2 pull-down correction and "bad edit" correction, the latter however only for 6800 and 6600 models. Additional functions include "flicker-free" multi-stream scaling, and display Gamma correction.
