ƒ Higher: Noise Filter settings instruct IP-Reach or Dominion to
transmit a variant pixel of video only if a large color variation
exists in comparison to its neighbors. However, setting the
threshold too high can result in the unintentional filtering of
desired page changes.
ƒ Lower: Noise Filter settings instruct IP-Reach or Dominion to
transmit most pixel changes. Setting this threshold too low can
result in higher bandwidth use.
Note: Lower Noise Filter settings (approximately 1 to 4) are
recommended. Although higher settings will stop the needless
transmission of false color variations, true and intentional small
changes to a video image may not be transmitted.
3. Analog-to-Digital Settings: The following parameters are best left to
IP-Reach or Dominion to automatically detect (on the RRC Menu
Bar, select Video > Auto-sense Video Settings), but a brief description
of each is included here.
4. PLL Settings: If the video image looks extremely blurry or
unfocused, the PLL Settings for clock and phase can be adjusted
until a better image appears on the active target server.
ƒ Clock: Horizontal sync divider to produce pixel clock. Controls
how quickly video pixels are displayed across the video page.
Changes made to clock settings cause the video image to stretch
or shrink horizontally. Odd number settings are recommended.
ƒ Phase: Phase values range from 0 to 31 and will wrap around.
Stop at the phase value that results in the best video image for
the active target server.
5. Color Settings: Gain control can be thought of as contrast
adjustment. Offset control can be thought of as brightness
adjustment.
ƒ Red Gain: Controls the amplification of the red signal.
ƒ Red Offset: Controls the bias of the red signal.
ƒ Green Gain: Controls the amplification of the green signal.
ƒ Green Offset: Controls the bias of the green signal.
ƒ Blue Gain: Controls the amplification of the blue signal.
ƒ Blue Offset: Controls the bias of the blue signal.
