UNIQUE TECHNIQUES
By definition, DSVP works with RGBS or
RGBHV video—signals where the sync is
run separately from the video—by
scanning all sync inputs, and obtaining the
frequency of the horizontal and vertical
sync signals. This information is then
transmitted to a computer, touch panel, or
other display system via RS-232 or
ethernet. DSVP technology is built into
Extron Matrix 12800 Series Matrix
Switchers and CrossPoint Plus Series
Matrix Switchers. The Extron VSS 100
Video Sync Separator can be used to
separate composite TTL level sync output
for DSVP verification when using video
formats with embedded sync such as
RsGsBs, RGsB, component video, S-video,
and composite video.
Problem Finder
With DSVP, problems can be tracked
down much faster, even from remote
locations, saving time and unnecessary
maintenance calls. Monitoring a complex
A/V system is easier with DSVP as any user
or technician can quickly determine which
inputs on the matrix are actually receiving
signals and what type/resolution of signal
is on a particular input.
E
xtron offers a variety of technologies to enhance and improve video images, but there’s one that actually goes
inside and helps troubleshoot a system, providing proactive service and support capabilities: Digital Sync
Validation Processing (DSVP™).
Using RS-232 or a computer running
the Extron matrix control software, DSVP
can help to determine if an active signal is
actually on an input, what the frequency/
resolution of a signal is on a particular
input, if a source has dropped out, or if a
source has been changed. With such
information, it is much easier to locate the
cause of a lost signal. If DSVP shows that
the signal at the source has dropped out,
then the user knows the source side is the
problem. If there is no signal at the
projector and DSVP shows there is an
active source on the input, then the
user/technician knows the problem lies
after the input of the matrix.
Consider the value of knowing that a
different source is on an input than was
expected. In big matrix systems, signal
changes are often made without all the
users or technicians being notified. Being
able to find this information out via DSVP
can save considerable time during
troubleshooting.
System Monitoring and Active
Updating of Touch Panels
DSVP can be used in conjunction with
other information sources to allow a
user to monitor and troubleshoot a
complex matrix system with ease.
