Digital Sync Validation Processing (DSVP ™ ) (CrossPoint 450 Plus sync BMEs) —
In critical environments or unmanned remote locations, it may be vital to
know that sources are active and switching. The DSVP feature 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 serial ports or LAN
port. The frequency information can be displayed on any control system
or in a Windows ® -based control program on a local-area network (LAN) or
Internet (IP) connection (figure 1-2).

RGB Delay (CrossPoint 450 Plus sync BMEs) — A switcher that includes a
CrossPoint 450 Plus sync BME 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 appears 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.
Rooming — Each switcher can be programmed to group multiple outputs to
specific “rooms”, allowing each room to have its own presets.
