7.3 Y/C DELAY
This option is used to set the Y/C delay of the source.
• Sometimes the timing of Luminance (brightness) and Chrominance (color) of the video
source signal may be slightly mismatched due to transmission delay, long S-Video cable
runs, or incorrectly encoded source material. This produces color fringing in the picture,
often most noticeable when edges in the picture show a red fringe. Y/C delay adjustment
can often correct this problem by allowing you to correctly match the Chrominance
(color) part of the video signal to the rest of the picture
• When Pixel is greater than 0, the Chrominance (color) signal is shifted to the right by one
pixel at a time. Moving the slider to the left moves the Chrominance signal to the left by
one pixel at a time
• Sub-Pixel makes shifting the Chrominance by less than one pixel possible. One unit of
Sub-Pixel = 1/4 of a pixel
7.4 NOISE REDUCER
Besides VXP noise reduction, you can also define noise reduction performed by the FLI2300 and
analog SD input chips.
• OFF will produce the best image quality from good video sources
• Low or Medium may help reduce noise from TV broadcasts or from most analogue
sources
• High or Super would normally only be required for exceptionally noisy video sources
• Setting excessively high noise reducer levels may soften the picture
• VXP Noise Reducer has effect on all (both SD and HD) video sources; Faroudja Noise
Reducer has effects on SD video sources only; Analog SD input 3DNR Noise Reducer
only effects the Analog SD video sources from Video 1, Video 2, S-Video 1, S-Video 2,
Component 3, and Component 4
7.5 SMOOTH SCALING
You can select different levels of smoothness when the image is scaled.
