To distribute digital signage over
coax, an HD encoder/RF modulator
converts the output of a digital signage
player into an HDTV channel.
That channel is broadcast over coaxial
cabling, and tuned in by HDTV
tuners built into the displays—no
set top boxes required. Since each
media player/modulator pair has its
own channel, any HDTV can tune
in any player’s output and display its
This distributed system using HD
encoder/modulators and coax saves
money three ways when compared to
a typical player-at-display system.
Save On Implementation
Binga’s Stadium sports bar in Portland, ME, uses ZeeVee ZvPro 250 to distribute HD video
and digital signage content over coax.
Player-at-display system: By placing
a media player at each display, it’s
possible to deliver unique messaging
to each. However, typically several
displays will share messaging, meaning
they could also share a player, but
that savings isn’t realized because the
system architecture requires a player
at each display.
Distribution via coax: Using encoder/
modulators and coax, one player can
serve an unlimited number of displays
by broadcasting its output to all
of them as a unique HDTV channel.
Additional players are assigned their
own HDTV channels, allowing all
players to serve all displays.
Save On Expansion
Player-at-display system: Adding six
displays requires six new players, and
home runs of cabling to each new
Distribution via coax: Using coax,
the six new displays may receive
their messaging from existing players,
meaning no additional expense
for media players. Wiring the new
displays means splitting the nearest
cable run, and adding lengths of coax
Save on Maintenance Costs
Player-at-display system: In a hightraffic
location service work on a
player located at a display is either
disruptive to business, or done after
hours at greater expense. That display
may be dark until repairs are
made, adding soft costs.
Distribution via coax: Players in the
coax system can live in a back room,
where service work is less costly. The
display associated with the failed
player can be switched to another
channel, eliminating downtime.
These savings make distributing
digital signage over coax a compelling
solution. In an installation where
coax cabling is already in place (virtually
eliminating wiring costs), its
value is remarkable.
