Description  - PDF Spec Sheet
Xintekvideo's NTSC Color Corrector Model VP900A goes to the root of color errors and provides the means to truly apply the proper correction.
Conventional color correctors are able to modify chroma phase and color saturation, but changing chroma phase and saturation independent of luminance gain and black level results in a violation of the constant luminance principle, i.e., in luminance errors. The Model VP900A provides not only video gain, chroma phase and gain adjustment, but it also gives full control of amplitude and pedestal for each primary color, permitting full color balance of highlights as well as low lights.
The VP900A features Xintekvideo's VIP technology. The VIP engine (Video Improvement Processor) is a proprietary system that utilizes recursive filtering techniques with motion compensation to provide over 9 dBs of random noise reduction in both luminance and chrominance. Independent noise reduction of Y and C permits system optimization for different types of random noise, e.g. "snow", color streaks, beats and other random interference. In the auto noise reduction mode, it analyzes noise in the input video and it automatically adjusts processing for optimum noise reduction.
