IN1606 and IN1608 Series Scaling Presentation Switcher • Operation

27

Auto Memory — Press the Navigation buttons to turn Auto Memory on or off for each 
input. The scaler 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 previously applied signals. When auto 
memories are disabled, the scaler treats every applied signal as a new source.

Auto Memory and Auto-Image Interaction

Auto Memory Auto-Image

Information

On

On

“New” signals and rates not previously detected by the 
scaler, are initially set up using default parameters, then 
Auto-Image is automatically applied. The next time the signal 
is detected, the values stored in the auto memory location 
are applied.

On (default)

Off (default)

“New” signals and rates not been previously detected by 
the scaler, 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 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. 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. Manual changes made to the image and picture 
controls are lost when a new rate is applied, a new input is 
applied, or after a power cycle.

Overscan — Press the Navigation buttons to select the overscan value for each input 
format. Choose between 0%, 2.5%, or 5%. Set default overscan mode through SIS 
commands (see the 

Overscan mode

 SIS commands on page 49).

Overcan is specific to each input signal type. This feature zooms and crops SMPTE input 
resolutions to mask edge effects and ancillary data that are common in broadcast signals. 
When the overscan mode is not at 0%, an Auto-Image on a SMPTE input rate (NTSC, PAL, 
SECAM, 480p, 576p, 720p, 1080i, 1080p, and 2K [2048x1080]) refers to the default input 
lookup table values instead of performing a “true” auto image. 

NOTE:  Overscan is valid only on SMPTE input rates (NTSC, PAL, 480p, 576p, 720p, 

1080i, 1080p, or 2K [2048x1080]) and is global for each video format.

Auto Switch — Press the Navigation buttons to turn the auto switch mode on or off, and to 
set the priority. The auto switch setting allows for basic, unmanaged, input switching based 
on the presence of active input signals. Auto switch mode options are:

• 

Disabled (off)

• 

Setting priority to “high to low” (highest numbered active input to the lowest)

• 

Setting priority to “low to high” (lowest numbered active input to the highest)

Factory Reset — Press and hold the Enter button to reset the device to factory defaults. 
The scaler retains the current firmware version, as well as communication and IP settings.
