DVS 605 • Operation

Aspect Ratio
Use either
Adjust
knob (
[ {
) to set the aspect ratio to
Fill
or
Follow
.
The aspect ratio setting is per input, and allows the user to select a new aspect ratio for
each input signal filling the entire output raster (using Fill, the default setting). For each input
rate to be displayed with its native aspect ratio, use Follow (4:3, 5:4, 15:9, 16:9, 16:10).
This setting has the correct letter box or pillar box settings visible under the Image Size and
Image Position Picture Controls.
When the DVS 605 is in the 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
, using one of the aspect ratio test patterns for a template. If
Auto
Memory
is enabled, then these settings are saved and recalled the next time the signal
is detected.
The DVS 605 clears the previous size and position settings whenever the aspect ratio
setting for an input is adjusted.
NOTE:
Unique SIS commands can set the device to Auto-Image and Fill or
Auto-Image and Follow, regardless of the current aspect ratio (see
Auto Memory
Use either
Adjust
knob (
[ {
) to turn
Auto
Memory
on (default) or off.
The DVS 605 stores 32 auto memories per input, with input configuration and picture
control data for each input. The default settings enable these memories to automatically
recall input and picture controls for signals that have been previously applied. When auto
memories are disabled, the DVS treats every newly applied input as a new source. Default
for Auto Memory is On.

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

(Default)
“New” signals and rates that have not been previously detected
by the DVS 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 to the
rate. Any manual changes made to the image and picture controls are
lost when a new rate is applied.
