nVidia introduced the Video Processing Engine or VPE with the GeForce 4 MX. It is a feature of nVidia's GeForce graphics processor line that offers dedicated hardware to offload parts of the MPEG2 decoding and encoding. The GeForce Go FX 5700 rolled out the VPE 3.0. The VPE later developed into nVidia's PureVideo.
5 Horizontal x 3 Vertical Taps Scaling & Filtering
Independent Hardware Color Enhancements and Digital Vibrance Control
Component out supporting 720i and 1080i
master sync generator to control the sync levels
interlacer to output 480i and 1080i interlaced modes and a TV encoder, which operates in digital-to-analogue converter (DAC) mode with Tri Level Sync. VPE supports the first two of these element and all that is required to ship a graphics board capable of YPrPb output is a TV encoder that supports tri-level sync, and to replace the 4-Pin S-Video connector with a 9 pin.
Nvidia's proprietary device driver is available for multiple operating systems and support for VPE has been added to it. Additionally, a free device driver named nouveau is available. This driver also supports the VPE hardware.
