Advanced Configuration - Extron electronics DVS 605 Series User Manual

Audio delay setting
The DVS automatically delays all analog and digital audio inputs to compensate for internal
video processing delay. Occasionally additional audio delay is required to account for other
signal processors, scalers, or display devices in a system. For these situations, the DVS
605 offers an additional 0-255 millisecond static global audio delay which can be set via SIS
command (see
Configuration
page 110) to eliminate audio "lip sync" issues.

Advanced Configuration

The following flowchart provides an overview of the Advanced Configuration submenu
The options are Auto-Image (on or off), aspect ratio (fill or follow), auto memory (on or
off), overscan (none, 2.5%, and 5.0%), switch type (dissolve or cut),
page 25, OSD duration, temperature (device reading only) and factory reset.

Auto-Image
Use either Adjust knob ([ {) to turn Auto-Image on or off (default).
When enabled and a new input frequency is detected, the DVS first applies an existing
Auto Memory for the signal (if Auto Memory is enabled), or, if no entry exists, performs an
automatic Auto-Image on the new signal. This automatically attempts to size and position
the image to fill the screen, with respect to the current aspect ratio setting.
With Auto-Image disabled, the DVS 605 applies default values to a new input if
Auto Memory is enabled but no Auto Memory exists.
Threshold settings
By default, the Auto-Image function considers any analog video with a >25% brightness
to be active video. Some video sources, such as dark PC backgrounds, or dark borders
around a presentation, may require a lower "Auto-Image threshold," to ensure incoming
video is properly sized and centered by the Auto-Image function. Other scenarios, such
as upstream analog twisted pair extension products, may require a greater Auto-Image
Threshold setting in order to allow the DVS 605 to ignore extraneous sync pulses that may
have been embedded in the RGB signals.
A global analog video Auto-Image threshold value can be set via an SIS command or using
internal web pages.
The range is 0% (black / ~0.0 VDC) to 100% (white / ~0.7 VDC), with a default value of
25%.
NOTE: The Auto-Image threshold setting affects only analog input signals, and has no
effect on digital inputs, which are sized and centered automatically.
