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 synchronization for the image. This can be used
to eliminate any black border surrounding the image. High values, both ne gative and positive can put the image out of sync.
• De-interlacing - i s used to improve vid eo stream image quality from analog devices. Select any of t he following options
from the De-interlacing drop-down list. Select None if de-interlacing is not necessa ry; Blending for improved image quality
that is not as processor intensive; Adaptive Interpolation perfor m s 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 performs de-interlacing of the video str eam by applying different filters depending on the motion in different
parts of the image. This w ill in most cases result in the best image quality.
• Antialiasing will minimize distortion known as aliasing, which happens when a high-resolution image is represented at
alowerresolution.
• For each video input 75 Ohm video termination can be enabled/disabled via the product's web page a t Video & Audio >
Video Input > Video termination. These terminations are enabled on factory default. In cases where the p roduct is to be
connected in parallel with other equipment, for optimum video quality, it is recommended that terminatio n be enabled for
only the last device in the video signal chain.
