Video Acquisition
Support for 4 x composite or 2 x S-Video inputs.
•
9 Bit analog-to-digital converter with two-fold ITU-656 oversampling (27MHz)
provide the most acurate professional quality image sampling available in
the market
•
Digital PLL for synchronization and clock generation from all standards and
non standard video sources e.g. consumer grade VTR
•
Enhanced horizontal and vertical sync detection
•
Increased luminance and chrominance bandwidth for all PAL and NTSC
standards
Video Scaler
•
Horizontal and vertical down scaling and up scaling to randomly sized
windows
•
Horizontal and vertical scaling range: variable zoom to 1/64 (icon)
•
Vertical scaling with linear phase interpolation and accumulating filter for
anti-aliasing (6 bit phase accuracy)
