Nvidia Pure Video
Nvidia PureVideo is a hardware feature designed to offload video decoding processes and video post-processing from a computer's CPU hardware to Nvidia's GPU hardware series GeForce 6 and later, GeForce M series (formerly known as GeForce Go); and Nvidia Quadro series. PureVideo is designed to work with media playback software, it can also be used for the decoding process of transcoding software. Nvidia's proprietary device drivers for Windows, Linux, Solaris and FreeBSD are PureVideo-enabled; with the appropriate (PureVideo-enabled) application software, the Nvidia driver will automatically use whatever hardware-acceleration is available on the Nvidia display-adapter.
All software HD DVD/Blu-ray players, as well as most software DVD players, are PureVideo-enabled. Microsoft's Windows Media Player and Windows Media Center also support Nvidia's PureVideo technology. Nvidia also sells its own PureVideo decoder software (which is a source of confusion, as Nvidia's decoder is not required and not used by third-party players), which serves as a DVD player with advanced post-processing capabilities. The degree of PureVideo's capabilities varies by generation.
In November 2008 Nvidia released a beta version of a closed-source device driver and open-source API called VDPAU (Video Decode and Presentation API for Unix) with PureVideo support for Linux, FreeBSD and Solaris.

Famous quotes containing the words pure and/or video:
“In verity, an independent world,
Created out of pure intelligence.”
—William Wordsworth (1770–1850)
“We attempt to remember our collective American childhood, the way it was, but what we often remember is a combination of real past, pieces reshaped by bitterness and love, and, of course, the video past—the portrayals of family life on such television programs as “Leave it to Beaver” and “Father Knows Best” and all the rest.”
—Richard Louv (20th century)
