For each input, select an aspect ratio from the
Aspect
Ratio
drop-down list (part of
figure 50, shown below).
Fill
— Scales the input signal to fill the entire video output.
Follow
— Follows the source signal aspect ratio, with respect to the current output
resolution setting. A black letter box or pillar box bars is applied for aspect ratio
compensation.
Fit
— Scales the signal up. Some of the image at either the top and bottom or the left
and right is cropped in order to fit the screen.
NOTE:
The selected input aspect ratio setting is applied to both the archive and
confidence outputs. If the confidence resolution is different, the applied aspect
ratio can not be maintained. For example, if the archive resolution is 1080p with an
aspect ratio of 16:9, and the confidence display is 1024x768 with an aspect ratio
of 4:3, the input aspect ratio selection can not be maintained for both.

Select (
enable
) or deselect (
disable
) the following check boxes for each input:
•
Auto-Image
— Select the check box to apply Auto-Image one time to the input.
When selected, Auto-Image is applied whenever there is a change in the input
sync. Auto-Image automatically sizes and centers the selected input. The processor
measures the sync frequencies of an incoming video source and uses an internal
table to set the active image area, total image area, and the sampling frequency.
NOTE:
When overscan is enabled, default values for the detected signal type
are used. When overscan is disabled, alternate timings can be detected.
•
Auto Memory
— Select the check box to enable Auto Memory. Auto Memory
recalls input and image settings for signals that have previously been applied. When
Auto Memory is disabled, the SMP 351 treats every new input as a new source.
Auto Memory and Auto-Image Features
Auto Memory Auto-Image Information
On
On
"New" signals or rates not previously detected by the
device are initially set up using default parameters.
Then, Auto-Image is automatically applied and
those values are stored. The next time that signal
is detected, the stored values in the auto memory
location are applied.
On
Off
"New" signals or rates not previously detected by the
device are set up using default parameters. If changes
are made manually to the input and picture settings,
an auto memory location is created and then recalled
each successive instance that the input is detected.
Off
On
When auto memory is disabled, each change in the
input sync is treated as a new signal, and Auto-Image
is triggered automatically. Any changes that are made
manually to the image and picture controls are lost
each time a new refresh rate is detected.
Off
Off
Each change in the input sync causes default values
to be applied to the rate. Any changes that are made
manually to the image and picture controls are lost
when a new rate is applied.
