Using Videohub Routers
Compact Videohub
Compact Videohub is a small router and is perfect when you need a bigger router in a small size, such as
in creative post facilities and broadcast trucks. It features 40 SDI inputs, 40 SDI outputs, reference input,
redundant power supply connections and powerful Videohub routing control software.
All SDI connections support auto detection of SD, HD or 3G-SDI, and reclocking on all SDI inputs.
Simultaneous routing of 2K, HD, SD video and DVB-ASI are supported with Compact Videohub.
Remote router control is performed via 10/100Base-T Ethernet, serial or USB 2.0 and then shared over
an IP network in much the same way as USB printer sharing. If router control is performed via Ethernet,
the integrated “Videohub Server” is used and you need only provide an Ethernet cable to connect
Compact Videohub to your Ethernet network switch.
If router control is performed via USB 2.0, you must nominate a computer to be the “Videohub Server”
and to perform Videohub sharing via USB. You can use almost any computer for the Videohub Server and
you don’t need a dedicated or powerful computer for this task. However the Videohub Server computer
must remain powered on at all times so that Videohub settings can be modified. You will need to provide
a standard USB 2.0 type A-B male cable to connect Compact Videohub to the server computer.
The same USB cable can be used for applying occasional internal software updates. Videohub Setup
will prompt you if an update is required. The utility runs on the Videohub Server computer and uses the
USB 2.0 connection to update your Videohub.
Third party router controllers can control Compact Videohub via Ethernet, or as an RS-422 slave device,
for router crosspoint switching. The Videohub Ethernet protocol, RS-422 protocol and RS-422 pinout
diagram are documented in the Developer Information section of this manual.
Compact Videohub is 2 rack units high and less than an inch thick. You will need to leave enough space in
your equipment rack to install the Compact Videohub hardware. You can rack-mount Compact Videohub
facing forwards or reversed, or even mount it in the rear of the rack to leave space for other equipment.
If you don’t have a rack, then you can leave it in a safe place on the floor!
The Compact Videohub includes one universal power supply for use in all countries. A second power
supply can be purchased to ensure continued operation should one fail. You will need to provide a
standard IEC cord with a C13 connector for each power supply. We recommend connecting and powering
two power supplies at all times, which means two mains power sockets will be required. A third power
socket will be required if you decide to use a dedicated server computer.
