Auto Memories and Auto-Image Interaction

Auto memories Auto-Image

Action

On	On	New signals or rates that have not been previously
		detected by the DVS 510 are initially set up using default
		parameters, then Auto-Image is applied and the values are
		stored. The next time that signal is detected, the values
		stored in the auto memory location are applied.
On	Off	(Default) New signals or rates that have not been
		previously detected by the DVS 510 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 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.

Aspect Ratio submenu

The aspect ratio control allows you to select between Fill (the input signal at each rate fills the entire output raster), or Follow (the input signal at each rate is displayed with its native aspect ratio [default setting]).

•In fill mode, if you want an aspect ratio adjustment for a single input rate, you can set up the correct size and centering by using one of the Aspect Ratio test patterns as a template (see “Test Pattern submenu” on the next page). If auto memories is enabled, this setting is saved and recalled the next time the signal is detected.

•In follow mode, each input rate is displayed with its native aspect ratio (4:3, 5:4, 16:9, or 16:10). You can view the correct letterbox or pillar box settings by pressing the Size or the Position button. If a single input is to fill the entire raster in follow mode, you can manually set the position (center) to 0,0 and the size to match the current output rate (see “Picture Controls” on page 36).

To select the aspect ratio mode:

1.From the Advanced Configuration menu, press Next until the Aspect Ratio submenu is displayed.

2.Rotate either Adjust knob to select the desired mode.

RGB Delay submenu

The RGB delay feature applies a brief delay before displaying a new input on a screen, allowing the display device to adjust to the new sync timing. This delay shows the viewers a blank screen, masking any glitch during switching. The RGB Delay options are 0 to 5 seconds in 0.1-second increments.

To set the RGB Delay time:

1.From the Advanced Configuration menu, press Next until the RGB Delay submenu is displayed.,

2.Rotate either Adjust knob to select the amount of delay.
