Video input
• Enter a descriptive name for your video source in the Video source name field.
• The values in the Offset Adjustments fields affect the horizontal and vertical synchroniz ation for the image. This can be used
to eliminate any black border surrounding the image. High values, both ne gative and positive c a n put the image out of sync.
• De-interlacing - is used to improve video stream image quality from analog d evice s. Select a n y o f the f ollowing options
from the De-interlacing drop-down list. Select None if de-interlacing is not necessary; Blending for improved image quality
that is not as processor intensive; Adaptive Interpolation performs de-interlacing of the video stream by applying different
filters on the image. This may give a better result than Motion Adaptive Interpolation in rare cases; Motion Adaptive
Interpolation perfor m s de-interla cin g of the video stream by applying different filters depending on the m otion in different
parts of the image. This will in most cases re sult in the best image quality.
• Antialiasing w ill minimize distortion known as a liasing, which happens when a high-resolution im age is represented at
alowerresolution.
• For each video input 75 Ohm video termination can be enabled/disabled via the product's web page at Video & Audio >

connected in parallel with other equipment, for optimum vide o quality, it is recom m ende d that ter m ination be e nabled for
only the last device in the video sig nal chain.
