Auto Memory

The DVS 304 stores 16 auto memories with input and picture control data for each input.
The default settings enables these memories to automatically recall input and picture
controls for signals that have been previously applied. By disabling auto memories, the
DVS 304 will treat every newly applied input as a new source. Default is on.

“New” signals/rates that have not been previously detected by the
DVS 304 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.

“New” signals/rates that have not been previously detected by the
DVS 304 are set-up using default parameters. If manual input and/or pic-
ture settings are made to the input, an auto memory location is
created and recalled each successive time the input is detected.

Each change in input sync 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.

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

Settings Saved When Auto Memory Is On.

Aspect Mode

The aspect mode setting is global, and allows the user to select between each input signal
filling the entire output raster (Fill), or for each input rate to be displayed with its native
aspect ratio (Follow - default setting).
When in the Fill mode, if an aspect ratio adjustment for a single input rate is desired,
the desired setting (4x3 or 16x9) can be made in the input config menu by adjusting the
aspect ratio setting. If auto memories is enabled, then this setting is saved and recalled the
next time the signal is detected.

It is strongly recommended that the aspect ratio mode setting be used on initial setup of
the DVS, or input rates that have not already been saved as auto memories may not be
displayed as expected. This can be overcome by clearing the auto memories on the input
in question, and is done by holding in the front panel Menu button and the applicable
input button simultaneously for four seconds. Alternatively it can be cleared on a rate by
rate basis by applying a one time auto image.
