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. ==VPE 1 == *hardware MPEG2 decoding, *inverse quantization (IQ) *inverse discrete cosine transform (IDCT) *motion compensation *colour space conversion (CSC) functions *hardware subpicture alpha blending *Adaptive De-interlacing *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. *geforce 4 420/440 go〔(【引用サイトリンク】url=http://www.techdata.com/business/toshiba/Files/resources/NVIDIA%20GeForce4%20Go%202002-03.pdf )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Video Processing Engine」の詳細全文を読む スポンサード リンク
