Digital Sync Validation Processing (DSVP ™) (computer video group) —
In critical environments or unmanned, remote locations, it may be vital to
know that sources are active and switching. Extron’s DSVP confirms that
input sources are active by scanning all sync inputs for active signals. DSVP
provides instantaneous frequency feedback for composite sync or separate
horizontal and vertical sync signals via the switcher’s RS-232 ports or
Ethernet port. The frequency information can be displayed on any control
system or in the Windows-based control program on a LAN or Internet
Protocol (IP) connection (figure 1-2).

RGB Delay (computer video group) — The switcher can briefly blank the RGB
video output while it switches to the new input’s sync source, and then
switches the RGB signals. This allows a brief delay for the display to adjust
to the selected input’s sync timing before displaying the new picture, which
will appear without glitches. RGB delay, also known as Triple-Action
Switching
™
or video mute switching, is user selectable from 0 to 5 seconds, in
half-second increments.
