This guide is intended to describe
installation options you would use in commercial
installations (such as a sports bar). For installations
with less than 16 displays that will be
used at the same time, please see our

A NetPlay distribution system is a
"virtual matrix" switch. You can
add as many sources and displays as
Live HDMI Sources:
NetPlay AV uses the VTX encoders to
bring all your "live" HDMI sources into
the matrix system. This will be
any source device with a HDMI output
that does not fall into the directly
integrated categories below.
Camera Sources: IP
cameras and most NVRs can be directly
integrated in the matrix system without
needing VTX encoders for these.
File Sources: File
sources such as movie/music
libraries, digital signage videos, and
promotional videos can also be directly
integrated in the matrix system.
Standard TV Displays:
Standard TVs will use the VRX decoders
to provide HDMI video, audio, and
Mobile players: Mobile
devices (such as tablets and smart
phones) can play back NetPlay video
sources directly. You will need to
purchase the mobile streaming license
for the system (one license per system,
not per player). If you need to
support a large number of mobile
devices, you will need the multicast
license and a multicast capable wireless
To determine the equipment required,
simply purchase enough VTX encoders for
all your "live" HDMI sources and VRX
decoders for your standard TV displays.
audio for video distribution:
In most commercial installs, your audio speaker solution will consist
of a few audio zones (usually defined by
seating areas) which are powered by
speakers wired back to a central
equipment rack. We refer to this
as "centralized audio".
You may also have some rooms where the
audio is driven by speakers attached to
the TV. We refer to these rooms as "distributed audio".
You can also use a combination of these
if needed in your installation.
For "centralized audio", you will use
our CMX-A2 DSP audio switch in your
equipment rack. This switch will
handle all the digital and analog audio
switching, volume control, and lip sync
correction. The outputs of the CMX
switch will be routed to your fixed gain
power amps and then speakers. The
CMX digital outputs can also be sent to
multichannel amps in your rack.
With "centralized audio", we also
support audio return channel (ARC) via
network. This allows you to use
your centralized speakers to play the
audio from apps on your smart TV.
Simply connect the optical audio output
of the TV to the optical input of the
VRX to enable ARC back to the CMX-A2/NAB
For "distributed audio", the audio will
be directly provided in each room from
the HDMI or analog outputs of the VRX
decoder. When using speaker bars
or surround sound receivers it is
usually better to route the HDMI from
the VRX to the TV and then use the
optical output of the TV to the audio
Mobile players will receive the audio
directly with the video stream.
NetPlay Audio (music)
All NetPlay AV solutions support NetPlay
Audio functionality for every room.
Stream music from your mobile device,
listen to a cloud audio service, or
playback audio files from a local
network library. For public
venues, it is important that you obtain
the proper licensing for commercial use
of music. Pandora for business is
a simple way to cover this and is
supported on our devices.
For "centralized audio", all the NetPlay
Audio features will be provided by the
NAB100 card inside the CMX-A2 DSP audio
switch. This card can provide
mobile streaming, cloud audio, and file
audio for up to 8 users at the same
For "distributed audio", all the NetPlay
Audio features will be provided by the
VRX decoders in each room. If you
have rooms that are music only (no
display), you can use NBX022 instead of
VRX. Each VRX can provide a
independant or synchronized music stream
to the user in that room.
NetPlay AV provides IR, RS232, and CEC
control for all your connected source
and display devices. This control
is provided via network from your
control system without the need to
additional IR or RS232 ports or
Each VRX decoder can control the
attached TV and receiver/speakers via
IR, RS232, or CEC.
Each VTX encoder can control the
attached source via IR or RS232.
NetPlay network and wiring
NetPlay will be integrated on the
commercial standard network. We
recommend that the NetPlay video system
runs on separate switches that are tied
to the rest of the network at a single
The network switch or switches will need
1 port for each VRX decoder and 1 port
for every 2 VTX sources.
The network router will need a DHCP
server enabled (this is default on
nearly all routers). You must make
sure that the DHCP range is sufficient
for all devices.
The network switch ports connecting to
VTX devices should be 1000mpbs capable
(and use Cat6 cables).
The ports for VRX devices should be
100mbps or higher. Most switches
support both speeds.
All NetPlay devices should be on the
same subnet if possible. If this
is not possible, routing rules must
exist between the subnets. VLANs
are not required or recommended.
Devices should have access to the
internet for firmware updates or cloud
Because there are more than 16 displays,
all network switches that will carry
video traffic must be IGMP snoop
capable. You must also have 1
switch with IGMP query capability.
We recommend using 1 Cisco SG300 switch,
with additional Cisco SG200 switches as
Wiring can be via any combination of
ethernet technology. Cat5/5e/6 is
the easiest and should be used whenever
possible. For retrofit application, you
can use existing RG59/RG6 coax via MOCA
ethernet over coax. We recommend
the ActionTec ECB2500 adapters.
Wireless ethernet can be used as a last
resort, since interference can degrade
picture quality. NetPlay video
streams are ~20Mbps each.
NetPlay Mobile or DTV Game control
restaurant or sports bar applications.
They provide full system control via
your iPad or Android device including IR
control for all your TVs and sources.
Any of the supported control systems
(seen at the bottom of the page) can
provide commercial system control.
NetPlay equipment ordering list:
