Video Processing Engine

VPE 1

• hardware MPEG2 decoding,
• inverse quantization
• inverse discrete cosine transform
• motion compensation
• colour space conversion 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 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
