Welcome
Thank you for purchasing Videohub for your facility.
We hope you share our dream for the television industry to become a truly creative industry by
allowing anyone to have access to the highest quality video.
Previously high end television and post production required investment in millions of dollars of
hardware, and professional SDI routing switchers have always been way too high in cost for most
people to afford. HD-SDI is even worse and until now, only the largest post production and television
facilities could afford HD-SDI routing. Videohub changes all that and Broadcast Videohub even
enables you to pipe 2K film around your studio just like video. We hope you get years of use from it
and have lots of fun connecting everyone in your facility together!
This instruction manual should contain all the information you’ll need on installing your Videohub,
although it’s always a good idea to ask a technical assistant for help if you are not sure what IP
addresses are, or if you don’t know much about computer networks. Videohub is easy to install,
however, there are a few slightly technical preferences you will need to set after you install it.
We think it should take you approximately 5 minutes to complete installation. Please check our web
site at www.blackmagic-design.com and click the support page to download the latest updates to
this manual and Videohub software.
Lastly, please register your Videohub when downloading software updates so we can keep
you updated when new software is released. We are constantly working on new features and
improvements, so we would love to hear from you!

Introduction
Videohub is a professional routing switcher compatible with both High Definition SDI and Standard
Definition SDI video and also includes remote control routing. Videohub is designed to connect to
both HD-SDI and SD-SDI video devices. In addition, Broadcast Videohub supports 3 Gb/s SDI for
use with 2K film and HD 4:4:4 video. Workgroup Videohub includes a HD-to-SD down-converter
and a keying frame store.

Routing control of the Videohub is easy as it connects to any computer on your local area
IP based network. One computer on your network connects to Videohub via plug and play USB
connection, and shares the Videohub with other computers on your network in a similar way to USB
printer sharing.
The computer you connect the Videohub to via USB is called the “server”.
Rack-Mounted Workgroup Videohub
You don’t need to worry about technical details as most of the setup is automatically done for you
by the Videohub installer software. You only need to run the installer with the Videohub connected
to the USB port on that computer, and the software automatically knows it’s the ‘server’.
Connect the server computer to the
USB port on the rear of the unit.
How to use your Videohub
Installing a Videohub
Setting Up the Network
The next step is to install the Videohub software on the other computers used to control the
Videohub on your network. As the Videohub is not directly connected to these computers, the
software on these computers will need to talk directly to the server computer that is connected
to the Videohub via USB. All you need to do is tell the other computers which computer on your
network is the Videohub ‘server’.
Because the software application controlling the Videohub is really a client, even on the physically
connected server, the Videohub control application can be run from any computer within the
Videohub ‘network’. The IP sharing is done via the USB driver, so you don’t need to be always
running the application on the server computer. This lets you use one of your editing systems as a
server as long as the power is left on when you need to use the Videohub.
Apple Mac OS X, Windows XP or Windows Vista computers can be the Videohub ‘server’ or any
number of ‘clients’ connected to the ‘server’ via USB.
This instruction manual will cover how to install Videohub in your facility, as well as configuring
and using Videohub.

Installing a Videohub
Walk-through: Installing a Videohub
Planning your Videohub installation
You will need to leave enough space in your equipment rack to install the Videohub hardware. The
Broadcast Videohub is 8 RU (rack units) high and less than 3 inches deep. The Workgroup Videohub
is 3 RU high and less than 1 inch deep.
The Workgroup Videohub requires a single power socket. The Broadcast Videohub includes two
power supplies, with thumb screw fasteners, to ensure continued operation should one fail. We
recommend connecting and powering both power supplies at all times which means two power
sockets will be required.
Your SDI cables should have regular-sized BNC connectors on each end of the cable. Press the BNC
connector against a BNC port on the Videohub and then rotate the connector clockwise to secure
it. Attach the other end of the cable to your other SDI equipment and secure it in the same manner.
To disconnect the SDI cable, rotate the BNC connector counter-clockwise and remove the cable.
It’s easy to connect and disconnect SDI cables to and from your Videohub. However as you attach
more SDI cables, you might find it tricky to fit your fingers between the BNC connectors. You can
use a BNC Removal Tool, from third party vendors, to help make this task easy even when your
Videohub has many cables connected. The Broadcast Videohub includes a 12” BNC Removal Tool
for this purpose.
Connecting your new Videohub to a “server”
Prior to connecting any devices to the Videohub, you must choose a computer to be the Videohub
“Server”. You can use almost any computer for the Videohub Server and you don’t need a
dedicated computer for this task. If you do decide to use a dedicated computer, this could be
a great use for an old computer which is no longer fast enough for other work. Alternatively you
could use a very small computer, such as a Mac Mini, which could be hidden in an equipment
rack along with your Videohub.

Installing a Videohub
When launching the Videohub application for the first time, after installing the software, the
“Welcome to Videohub” window will appear. This window prompts you to choose which view of
the Videohub you would like.
If you are configuring the Videohub software on a client computer, choose either “Simple” or
“Personal Router Control” to only see your video routing connections.
If you are configuring the Videohub Server, it would be best to choose the third option, “Main
Router Control” so you can see every option and every connection in your facility.
You can click on the view which you prefer or press the shortcut key combination. You can easily
change this later by pressing the shortcut keys or by choosing the router view from the Window
menu in Mac OS X or the View menu in Windows.
The respective shortcut keys for Simple, Personal and Main Router Control are:
• on Mac OS X; Comand 1, Command 2 and Command 3
• on Windows; Control 1, Control 2 and Control 3.

Installing a Videohub
Configuring Videohub
Renaming of labels for Videohub inputs and outputs, or changing routing settings is done via the
Videohub router control software. This acts as a client and talks to the USB server that’s connected
to the Videohub. All computers on your network communicate with Videohub through the
Videohub control software.
This client control software is network enabled so it allows either Mac™ or Windows™ computers
to control the Videohub regardless of the operating system the server is running. Every computer
on your network that is running the Videohub control software will automatically update its status
when another user makes a connection or label change. This allows any number of users to control
the Videohub simultaneously.

How to use your Videohub
Installing a Videohub
All Videohub preferences are configured through the Videohub control software, regardless of
whether performed on the Videohub server or on a client computer. The Videohub preferences
can be found under the “Edit” Menu in the Windows™ software or under the “Blackmagic Design
Videohub” menu in Mac OS X™.
13
The preferences are split in to two sections, Videohub Server Preferences and Customize Labels.
1. Videohub Server Preferences
The Videohub Server computer will need a “static IP address” so that the other computers
on the network can always find it. Please discuss this with your network administrator who will
probably want to configure this for you. Avoid using DHCP on the Videohub Server computer
as this will potentially cause the IP address of the server to change and the Videohub clients
will lose communication with it. DHCP (dynamic allocation of IP addresses) can be used on
any other computers on the network which are running the Videohub software as a client.
You should make a note of the static IP address on the Videohub Server computer as you
will need to enter this address in to the “Videohub Server Preferences” on each of the client
computers which are running Videohub software.
On Mac OS X, go to System Preferences>Network and look at the IP address in the
configuration information for your Ethernet or Airport network. Ensure the network
configuration is set to either “Using DHCP with manual address” or “Manually”.
Network PrefPane in Mac OS X 10.5 set to “Using DHCP
with manual address” to provide a static IP address.
On Windows XP, go to Start menu>Control Panel>Network Connections. Right-click on your
LAN connection, which is usually “Ethernet” or “Wireless Network Connection”, and choose
Properties. Select “Internet Protocol (TCP/IP) and click the Properties button. Ensure “Use
the following IP address” has been chosen.
On Windows Vista, go to Start menu>Control Panel>Network and Sharing Center. Click
“View Status” next to your connection. Click on Properties. Select “Internet Protocol Version
4 (TCP/IPv4)”. Click on Properties. Ensure “Use the following IP address” has been chosen.
The “Videohub Server” preferences are used to specify the address of the Videohub server.
This can be accessed through the “Videohub Server Preferences” window in Mac OS X and
Windows. If you are configuring this preference on the Videohub server computer, enable
the option to “Use Locally Connected Videohub”. This will automatically enable the correct
network settings, on the server computer, based on the Network control panel .
When the Videohub Client is first started, the “Remote Videohub IP address” field will be
set to “localhost”. All clients will need to specify the address of the server before they can
connect and control the Videohub. Ask your network administrator for this information and
then enter the IP address in to this field, eg 192.168.1.100.
How to use your Videohub

Once each client computer has the address of the server, the software interface will become
active and it will be able to control the Videohub.

2a. Customize Labels - Router Input, Output and Monitoring
The “Customize Labels” preferences are used to specify the labels assigned to each port.
These labels are saved on the Videohub server and will be seen by all clients. This is where
you enter labels for each device you connect to the video ports on the Videohub.
For example, you might have a Digital Betacam™ deck connected to ‘Input 21’ and ‘Output
21’ of the Videohub. In this case you could change the label to “Sony Digibeta” or even
“Doug’s Deck”. It really doesn’t matter what you label the inputs and outputs, but remember
that everyone on your network running the Videohub software can see the labels. This is
because label changes are system wide and are reflected on all clients.
If you’re working in non-Roman character set languages such as Japanese, Chinese, Korean or
Middle Eastern languages, then you can enter double byte unicode labels. This is supported
on both Mac™ and Windows™ based computers.

Installing a Videohub
2b. Customize Labels - Remote Connection and RS-422 Port Direction Settings
“Customize Labels” is also used to specify the labels and directions assigned to each RS-422
serial port. You can label these ports in a similar way to the video ports .
Remote “Out (Deck)” specifies that the port is connected to a deck that will be controlled
from another editing or design workstation.
Videohub can change serial port directions so you can connect both decks and workstations to
any port on the Videohub. Decks need to be set to Remote Out so they can be controlled.
Sometimes if you’re running deck to deck editing, the deck with which you’re editing and
setting in and out points, becomes a controller which controls another deck. In this case the
deck with which you set the in and out points becomes a controller device, so you would
configure this deck as Remote “In (Workstation)”. That’s because this deck is now controlling
another deck. Deck to deck editing is not as popular as it once was but with Videohub it’s
still easy.
Remote “In (Workstation)” specifies that the port is connected to a workstation that will send
data through its RS-422 port so it can control decks and other devices. A good example of
this is a capture card running in a Mac or Windows computer. It needs to capture clips from
in and out points on a tape deck, so the capture card will send remote commands through
the Videohub. This is why you need to choose Remote “In (Workstation)” when connecting
a workstation such as DeckLink™, Multibridge™, Avid™ or Discreet™ to Videohub.
RS-422 port directions are set in the Customize Labels window (Windows View)

Using Videohub
To control Videohub from computers other than the Videohub server, you should install the software
on to each client computer.
The first time a client is started on a machine its interface will appear disabled and it must be
configured with the server IP address. The interface will also be disabled whenever the Videohub is
physically disconnected from the Videohub server.
Choose between Personal, Simple or Main Router Control depending upon how many connections
you want to see.

Blackmagic Videohub supports “one-to-many” routes. This means that any video input, such as a
HD deck, can be sent to one or more monitoring outputs. On the Workgroup Videohub, one input
could be sent to as many as 12 monitoring outputs, while on the Broadcast Videohub, one input
could be sent to as many as 72 outputs!

Using Videohub Main Router Control
The RS-422 port on the deck can be routed to the another RS-422 port of opposite direction on
the Videohub (for example to connect a deck to an NLE workstation). Unlike the video, RS-422
control is point to point, so when you connect two devices together, one will disable so it cannot
be accidentally connected to another port. To change the control port connection, just change the
connection to another port. Or you can choose to Disconnect the RS-422 port completely.
The figures to the right show the Remote 19 RS-422 port being routed to the
Panasonic D5 Deck. Due to the direction in which the ports have been configured,
RS-422 commands will now be sent from Port 19 to Panasonic D5 via Videohub.
Note that changing an RS-422 deck control route will affect other ports involved in
the routing - if Port 1 and 2 are connected together, and you connect Port 3 to Port 2, Port 1
will become disconnected.
Note: RS-422 ports must be configured in opposite directions (“Remote In” or “Remote Out”) to
be allowed to connect.
•
Remote “In (Workstation)” specifies that RS-422 commands will flow into the Videohub
from a connected device. This configuration direction would allow an NLE workstation
to send control commands to a deck.
•
Remote “Out (Deck)” specifies that RS-422 commands will flow out of the Videohub to
a deck connected to the Videohub. This configuration direction allows a deck to receive
control commands.
Remote In control ports can only be connected to Remote Out ports, and Remote Out ports can
only be connected to Remote In ports. If you cannot set two devices to connect together, then you
might need to check your Remote In/Remote Outdirection settings in the preferences.

Using Videohub Locking
Often you may not want other people in your facility to change the route of a signal you are
working with. This is important when outputting a master ot tape, and you don’t want anyone
changing the input of the deck from your setting.
Videohub supports locking to prevent people on other workstations from changing your routes.
To lock an output, simply click the “unlocked” icon next to the port’s drop-down list. The icon will
change to a “locked” image and other people are now unable to make changes that impact your
port.
After you have locked a port the interface of other clients will change so the port becomes “grayed out”.
If ports on your interface appear grayed out it simply means that another user has locked the port.
If you have locked a port it will become unlocked as soon as you change its route. You may then
relock the port if you wish to prevent further changes by other users.
The Videohub control software running on the Videohub “server” can unlock any locked output. If
you wish to over-ride someone else’s lock setting, simply make the change on the Videohub server.
This is nice if someone is controlling the Videohub from their notebook, and they leave the office,
with a destination locked!
Note: Locking serial ports can have far-reaching effects as any new serial route involving your port will
be disallowed for other users. For example, if Serial Port 1 is connected to Serial Port 2 and you lock
Serial Port 2, no other users can establish a route to Serial Port 2, even though you locked Serial Port 1.

Workgroup Videohub (only) - Real Time Down Conversion
The Workgroup Videohub contains two Real Time Processing Units currently setup for HD-to-SD
Down Conversion and a Keying Frame Store.
22
The HD Down Converter can be used to convert an HD signal to any of the Videohub inputs to an
SD signal to be routed out to any monitoring or output port.
To use the Down Converter:
•
First you need to send an input into the down converter. To do this, select an input from
the Processor>Down Converter Video menu (see “Step 1”). This input needs to be an
HD source.
•
Next select “Down Converter” on any output menu. The output of the down converter
is available in the menu on all Videohub outputs, and can be selected and sent to any
or all outputs. (see “Step 2”)
Only one source HD signal can be down converted at a time because there is only one down
converter in the Workgroup Videohub. The down converted signal can be routed to any number
of output ports. In some cases where you want to impress your clients, you could run two monitors
from the Workgroup Videohub into your edit suite, and have both HD and SD video monitoring
at the same time.

Workgroup Videohub (only) - Keying Frame Store
The Keying Frame Store is used to key a user-supplied image onto one of the input video signals.
23
Note: The dimensions of the image should match the input signal resolution as listed below.
NTSC 720 x 486
PAL 720 x 576
1080 HD 1920 x 1080
720 HD 1280 x 720
Images of invalid dimensions will be cropped or appear only in the top-left corner of the output.
Input images can be supplied in many formats including Photoshop, Bitmap, PICT, Targa and
others. The image should contain a valid alpha channel. Simply copy images you wish to alphablend into the “FrameStore” folder on the Videohub “Server” machine.
•
•
Under Windows XP and Windows Vista, the “FrameStore” folder can be found in the
“Server” subdirectory of the folder you installed Workgroup Videohub at (normally C:\
Program Files\Blackmagic Design\Blackmagic Videohub\Server).
Windows view
Under Mac OS X the “FrameStore” folder can be found at “/Library/Application
Support/Blackmagic Design/Videohub”
The pictured example on the right shows “No Image” indicating that there are no images available
on the server. If multiple images are available, the “No Image” text will be replaced by a drop
down menu containing the names of the images.

Workgroup Videohub - Keying Frame Store (continued)
Framestore images can be copied into this folder at any time. Once the Videohub has
recognized the images they will be immediately available for keying. Videohub will recognize the
images immediately when they are placed in the folder, so you just need to copy them into
the correct location.
24
To use the Keying Frame Store:
•
Select the video signal you wish to key against from the “Frame Store Video” dropdown menu under the “Processing” menu. This will also determine the video format of
the output of the frame store.
•
Select the image you wish to key onto the signal from the “Frame Store Graphic” dropdown menu under the “Processing” menu. This will then download the image into
the frame store on the Workgroup Videohub, and allow this frame to be output to
any other output on the Workgroup Videohub. If you look at the image as it is being
loaded, you will see it download into the Workgroup Videohub.
Select “Frame Store” from the drop-down list on any monitor or video output port on the
Workgroup Videohub. You can output the frame store to any or all of the video outputs on the
Workgroup Videohub. (see “Step 3” image below)

Troubleshooting
Q:The client software interface is always disabled.
A: This could be for several reasons –
The client is not connected to the Videohub server.
In this case, check the Question below titled “The client software cannot connect to the
Videohub server”.
If this is not the cause, then the Videohub might not be physically connected to the host
server computer. In this case, try the following:
The client interface is always disabled when the Videohub is not connected to the server via USB.
Ensure there is a USB connection between the Videohub and the server computer.
When the USB connection is running the light next to the USB connector on the Videohub will
blink intermittently indicating the USB is communicating correctly.
If this does not solve the problem, then the Videohub might not have been detected by the
Videohub server. Try the following:
1.
Ensure the drivers have been installed on the server by running the installer.
2.
Disconnect and reconnect the Videohub’s USB connection, on reconnect it should be
detected by the server – allow any uninstalled drivers to be installed.
3.
Uninstall the server software and repeat the installation process.

Troubleshooting
Q: The client software cannot connect to the Videohub server. In this case, check:
1. Is the Videohub server computer turned on? The Videohub server computer must
be running for clients to control the Videohub.
2. Ensure the IP address of the Videohub server is correctly specified in your preferences
on each client computer on your network.
3. Check that you have network connectivity to the Videohub server.
4. Ensure the Videohub server does not have TCP port 9990 blocked by a firewall. This
port is automatically opened by the installer if possible. It may have inadvertently
been closed by server software updates or user intervention.
5. Is the server service running on the server computer (Windows XP and Windows
Vista)? Check:
•
•
•
Double-click on “Administrative Tools” in the Control Panel (ensure you have
“Classic View” enabled)
Double-click on “Services”
Ensure the word “Started” appears under the “Status” column for the
“Blackmagic Videohub Daemon” service. If it does not, click on the service and
select “Start the service”.

or becomes noisy. Broadcast Videohub will continue to work even if the fan stops running.
However a working fan will help to extend the life of Broadcast Videohub for many years and we
recommend the fan be replaced if it should ever stop running.
The fan is designed to be replaced without needing to switch off power to the Videohub. Remove
the four screws on the fan cover and lift up the cover gently. You will see the colored power
cables connecting to a plug on the Videohub. Gently remove the plastic plug from the Videohub.
Remove the two screws which attach the faulty fan to the fan cover. Replace the faulty fan with the
spare fan by following this process in reverse. The spare fan should immediately start running.

Videohub Workflows
This example shows Workgroup Videohub connecting to other SDI equipment including an SDI
deck, CRT and DVI monitors and video capture cards. Broadcast Videohub connects in exactly the
same way. Analog equipment, such as a Betacam SP deck, can be connected to Videohub via a bidirectional SDI-to-analog converter, such as Broadcast Converter or any Multibridge.

Blackmagic 2K Format
The latest Blackmagic Design products use the new 3 Gb/s SDI video, which allows twice the data
rate of traditional HD-SDI video. We thought it would be a really nice idea to add 2K film support, via
this new 3 Gb/s SDI technology, so we could simplify feature film workflows. With the popularity of
Blackmagic Design editing systems worldwide, now thousands of people can benefit from a feature
film workflow revolution.
This information includes everything product developers need to know for building native 2K SDI
equipment. Of course, all Blackmagic products can be updated, so if the television industry adopts an
alternative SDI-based film standard, we can add support for that too!
Frame Structure
‚‚ Transmitted at 23.98 or 24 frames per second as a Progressive Segmented Frame.
‚‚ Active video is 2048 pixels wide by 1556 lines deep.
‚‚ Total lines per frame : 1650
‚‚ Words per active line. One word consists of a sample on both data streams:
3072 (2048*3/2). See following page.
‚‚ Total active lines : 1556
‚‚ Words per total line : 3750.
‚‚ Fields per frame : 2, 825 lines each
‚‚ Active lines located on lines 16-793 (field 1) and 841-1618 (field 2).
Transport Structure
‚‚ Based on SMPTE S425M mapping structure 2.
‚‚ Timing reference signals, line number and line CRC insertion is the same as above.
‚‚ Optional ancillary data is inserted into both virtual interfaces.
‚‚ At present, only audio data is included: as per standard HD audio insertion (SMPTE S299M) the audio
data packets are carried on data stream two and audio control packets are carried on data stream one.
‚‚ During active video, 10-bit Red, Green and Blue data is sent in the following sequence:
Data stream1: Green_1, Red_1, Green_2, Green_3, Red_3, Green_4,…,Green_n-1, Red_n-1, Green_n.
Data stream 2: Blue_1, Red_2, Blue_2, Blue_3, Red_4, Blue_4, …,Blue_n-1, Red_n, Blue_n.
Diagrams on the following page show the vertical timing details with line numbers and Field, Vertical and
Horizontal bits for the Timing Reference Signal codes.
Final diagram shows the data stream formats around the optional ancillary data section of the horizontal
line. Note that each active pixel takes up three samples.
