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.
