Extron electronic DVS 204 12V Installation and Operation, cont’d, Blue mode, Enhanced Enh mode

Installation and Operation, cont’d

Blue mode

To aid in setup of the scaler’s color and tint, the Blue mode can be set from this submenu to “On” so that only sync and blue video signals will be passed to the display.

Use either the Adjust horizontal () or Adjust vertical () knob to specify this mode. The default is “Off”.

The Blue mode will be effective for YUV input signals. YC input signals will pass Y, but not C, so the output display will be black-and-white only.

Autoswitch (Autosw) mode

The Autoswitch mode causes the highest numbered input that has a signal present to be automatically selected. For example, if both Inputs 1 and 3 have active input signals, Input 3 will be selected.

From this submenu, use either the Adjust horizontal () or Adjust vertical () knob to specify this mode as “On” or “Off”. The default is “Off”.

The Autoswitch mode ignores the presence of an SDI input signal, so any input which is assigned an active SDI signal will not be selected.

Enhanced (Enh) mode

When the Enhanced mode is set “On”, automatic gain control of the video input signal is enabled. If the input signal level is too weak, the signal gain will be increased, and if the input signal level is excessive, the signal gain will be decreased.

From this submenu, use either the Adjust horizontal () or Adjust vertical () knob to specify this mode as “On” or “Off”. The default is “Off”.

The Enhanced mode will only be effective on composite and S-video input signals.

2:2 Pulldown detection (PAL Film mode detect) submenu

For the currently selected input, set this feature to “On” if the source is PAL video that originated in film. For standard PAL video sources, such as cameras, set this feature to “Off” (default).

This feature does not apply to NTSC video sources since film mode (3:2 pulldown) is automatically detected for those signals.

From this submenu, use either the Adjust horizontal () knob or Adjust vertical () knob to specify this mode as “On” or “Off”.

RGB delay (Triple-Action Switching)

With Triple-Action Switching, the DVS 204 switches to the new sync signal before switching RGB (video) signals. RGB delay allows the display device to adjust to the new sync timing after a brief delay (during which the display is blanked) before displaying the new picture, which will appear without glitches. Triple-Action Switching is also known as video mute switching.

Use the Adjust horizontal () knob or Adjust vertical () knob to select the blanking period (RGB delay time) from 0 seconds (default) to 5 seconds in 0.5 second steps.
