IN1606 Scaling Presentation Switcher • Operation 21
Screen Saver and Timeout — Press the Navigation buttons to select a Black (default) or
Blue screen saver color and a time-out duration.
When there is no active video on the selected input, the device can mute the video output to
black or blue for a set duration before disabling output sync. By default, the IN1606 outputs
black video and continually output sync (no sync time-out) with no active input applied.
The time-out duration can be set to Never (default), or to any duration from 1-500 seconds.
Auto-Image — Press the Navigation buttons to turn the automatic per-input Auto-Image
mode On or Off (default).
When enabled and a new input frequency is detected, the IN1606 first applies an existing
Auto Memory for the signal (if Auto Memory is enabled), or if no entry exists, performs an
automatic Auto-Image on the new signal. This automatically attempts to set an appropriate
size and position for the image to fill the screen, with respect to the current Aspect Ratio
setting.
Aspect Ratio — Press the Navigation buttons to set the aspect ratio setting of the active
input to Fill (default) or Follow.
When in Fill mode, if an aspect ratio adjustment for a single input rate is desired, the correct
size and center can be set up using Image Size and Image Position under Picture Controls.
If auto memory is enabled, then these settings are saved and recalled the next time the
signal is detected.
When in Follow mode, each input rate is displayed with its native aspect ratio mode with the
correct letter box or pillar box settings visible.
The IN1606 clears the previous size and position settings whenever the aspect ratio setting
for an input is adjusted.
Auto Memory — Press the Navigation buttons to turn the Auto Memory on or off for each
input. The IN1606 stores 32 auto memories per input, with input configuration and picture
control data for each video resolution. The default setting enables these memories to
automatically recall input and picture controls for signals that have been previously applied.
When auto memories are disabled, the IN1606 treats every newly applied input as a new
source.
Auto Memory and Auto-Image Interaction
Auto Memory Auto-Image Information
On On “New” signals/rates that have not been previously
detected by the IN1606 are initially set up using default
parameters, then Auto-Image is automatically applied.
The next time that signal is detected, the values stored in
the auto memory location are applied.
On (default) Off (default) “New” signals/rates that have not been previously
detected by the IN1606 are set up using default
parameters. If manual input or picture settings are made
to the input, an auto memory location is created and
recalled each successive time the input is detected.
Off On Each change in input sync, input switch, or power cycle
triggers an automatic Auto-Image. When auto memory is
disabled, each change in sync is treated as a new signal
and an automatic Auto-Image is triggered. Any manual
changes made to the image and picture controls are lost
each time a new rate is detected.
Off Off Each change in input sync causes default values to be
applied. Any manual changes made to the image and
picture controls are lost when a new rate is applied, a
new input is selected, or after a power cycle.
