4Getting Started
Introducing Blackmagic MultiView 16
Blackmagic MultiView 16 is a single rack SDI monitoring solution for displaying up to 16 SDI signals
simultaneously on a single monitor. This lets you monitor multiple video signals in virtually any video
format within studio or portable broadcast environments, for example previewing routed sources
in master control, or monitoring incoming feeds during live production. All video formats are auto
detected and can be displayed using layouts from solo, 2x2, 3x3 and 4x4 so you can view all 16 inputs
together on one screen.
Dedicated Ultra HD and HD multi view outputs let you connect the largest Ultra HD monitors and with
the 2x2 layout selected, it means up to four HD signals can be displayed in native 1920 x 1080 pixel
high definition. The HDMI multi view output switches between HD and Ultra HD based on the format
your monitor supports, so you can plug in any HDMI television and monitor your inputs instantly.
Blackmagic MultiView 16 can be operated using the built in control panel, or remotely via Ethernet or
serial connections if mounted in a location where you don’t have access to the front panel. Blackmagic
Design router controllers, such as Blackmagic Videohub Master Control and Blackmagic Smart Control
can control Blackmagic MultiView 16 via Ethernet and you can even use the powerful and intuitive
Blackmagic Videohub Control software.
Blackmagic MultiView 16 has a built in power supply with a standard IEC power connector.
Getting Started
Blackmagic MultiView 16

5Getting Started
Connecting SDI Sources and Monitors
Getting started with Blackmagic MultiView 16 is very easy. Simply plug your SDI sources into any of
the 16 SDI video inputs on the rear panel, and connect a monitor to the HD, 6G-SDI or HDMI multi
view outputs. Blackmagic MultiView 16 will automatically detect if your connected video sources are
SD, HD, 3G or 6G-SDI and instantly display them on your connected monitor. You can also connect
your sources to other video equipment via the loop outputs above each SDI input.
When connecting an HDMI monitor, Blackmagic MultiView 16 will automatically detect whether it
supports Ultra HD or HD and switch the HDMI multi view output accordingly. If you want to connect an
Ultra HD monitor via SDI, plug directly into the 6G-SDI multi view outputs. If you have an HD monitor,
plug into the dedicated down converted HD-SDI multi view outputs. All SDI and HDMI outputs can
be used simultaneously for Ultra HD and HD multi view monitoring.
Setting your Multi View Layout
Once your SDI sources and monitors are connected, select your desired multi view layout using
the front control panel buttons and rotary knob. You can choose from 2x2, 3x3 or 4x4. You can also
monitor any view in full screen mode by pressing the 'solo' and 'view' buttons. To see all you 16 views
on your connected monitor, select 4x4 multi view layout.
Step 1. Press the ' menu' button on the front control panel to open the settings screen on the LCD.
Step 2. Layout is the first setting in the menu, so it is always highlighted when you first enter the
settings menu. Press the 'set' button to edit the setting.
Step 3. Select 4x4 from the layout setting by turning the rotary knob on the front control panel.
Whenever a setting changes, you'll notice the 'set' button and the 'menu' button will start
flashing. This means a setting has changed and you can either confirm the setting change
by pressing the 'set' button, or cancel by pressing the 'menu' button.
Step 4. Press the set button to confirm your setting.
You should now see your connected SDI sources displayed on your monitor using the multi view
layout you selected. It's worth selecting the layout to best suit the number of SDI sources you have
connected to Blackmagic MultiView 16. This means you will maximize the views for optimum monitoring.
That's all you need to do to start using Blackmagic MultiView 16. Please continue reading the rest of
this manual to find out how to use all of Blackmagic MultiView 16's features.
Connect your monitor to Blackmagic MultiView 16's HDMI or
SDI multi view outputs.

The frame rate will conform to the ‘video format’ setting. For example, if 2160p29.97 is selected, the
HD output can be either 1080p29.97 or 1080i59.94 depending on whether you have chosen progressive
or interlaced. Similarly, when 2160p25 is selected, the HD output can be either 1080p25 or 1080i50.
SD Aspect
If 4:3 SD video is connected to your Blackmagic MultiView 16, check the ‘set to 4:3’ checkbox. This
ensures your 4:3 video displays using the correct aspect ratio.
If 16:9 SD video is connected, check the ‘set to 16:9’ checkbox to display the image correctly in its view.
Overlay
The ‘border’, ‘labels’, ‘audio meters’ and ‘tally’ overlay settings are also available in the front control
panel LCD menu. Check the checkboxes in the ‘overlay’ settings to enable each feature.
Overlay features are:
Borders: Lets you separate each view in a grid like pattern.
Labels: Makes 'view' labels visible or hidden. Labels can be changed using Blackmagic
MultiView Setup.
Audio Meters: Turns audio VU meters on or off for all the views. The first 2 channels
embedded in each SDI signal are displayed in each view, which means you can monitor
audio levels together with the picture.
The overlay settings in the ‘configure’ tab lets you turn overlay
features on or off such as borders, ‘view’ labels, audio meters
and SDI tally borders.
In the ‘configure’ tab you can change the ‘details’ settings
such as the layout of your multi view output, the Ultra HD
multi view video format, set the HD multi view to interlaced or
progressive, plus change the SD aspect ratio between 4:3 and
16:9 so your SD video source displays correctly.

connected to input 16, you can view tally borders around a view when its source is
switched to air. You can turn this feature on or off using the SDI tally overlay setting.
For tally to work properly, make sure you connect your Blackmagic MultiView 16’s inputs
so they match the input numbers on your ATEM switcher or tally may be displayed on the
wrong view.

Blackmagic Videohub Ethernet Protocol v2.3
Summary
Blackmagic MultiView 16 is compatible with the Blackmagic Videohub Ethernet Protocol. It is text
based and is accessed by connecting to your Blackmagic MultiView 16's IP address and TCP port 9990.
The multi view sends information in blocks which each have an identifying header in all caps, followed
by a full colon. A block spans multiple lines and is terminated by a blank line. Each line in the protocol
is terminated by a newline character.
Lines sent to the Blackmagic MultiView 16 can be terminated with line feed, carriage return or both.
Upon connection, the multi view sends a complete dump of the state of the device. After the initial
status dump, status updates are sent every time the multi view status changes.
To be resilient to future protocol changes, clients should ignore blocks they do not recognize, up
to the trailing blank line. Within existing blocks, clients should ignore lines they do not recognize.
Protocol Preamble
The first block sent by the multi view is always the protocol preamble:
PROTOCOL PREAMBLE:↵
Version: 2.3↵
↵
The version field indicates the protocol version. When the protocol is changed in a compatible way,
the minor version number will be updated. If incompatible changes are made, the major version
number will be updated.
Device Information
The next block contains general information about the connected Blackmagic MultiView 16 device.
If a device is connected, the multi view will report the attributes of the Blackmagic MultiView 16:
MULTIVIEW DEVICE:↵
Device present: true↵
Model name: Blackmagic MultiView 16↵
Video inputs: 16↵
Friendly name:
Unique ID:
Video processing units: 0↵
Video outputs: 16↵
Video monitoring outputs: 0↵

This example is for the Blackmagic MultiView 16 which has 16 sources and 18 views including solo
which is view 16 and audio which is view 17, referred to here as outputs.

Version 2.3 of the Blackmagic Videohub Ethernet Protocol
was released with Videohub 4.9.1 software.

Initial Status Dump
The next two blocks enumerate the labels assigned to the input and output ports.
INPUT LABELS:↵
0 VTR 1↵
1 VTR 2↵
…
↵
OUTPUT LABELS:↵
0 Output feed 1↵
1 Output feed 2↵
…
↵
Note: Input and Output labels are always numbered starting at zero in the protocol which matches
port one on the chassis.
The next three blocks describe the routing of the view ports.
VIDEO OUTPUT ROUTING:↵
0 5↵
1 3↵
…
↵
The next block describes the locking status of the views. Each port has a lock status of “O” for ports
that are owned by the current client (i.e., locked from the same IP address), “L” for ports that are
locked from a different client, or “U” for unlocked.
VIDEO OUTPUT LOCKS:↵
0 U↵
1 U↵
…
↵

The last block is the configuration block.
Layout: SOLO or 2x2 or 3x3 or 4x4
Output format: 50i or 50p or 60i or 60p
Solo enabled: True or False
Widescreen SD enable: True or False
Display border: True or False
Display labels: True or False
Display audio meters: True or False
Display SDI tally: True or False
Status Updates
When any route, label, or lock is changed on the multi view by any client, the multi view resends the
applicable status block, containing only the items that have changed.
If multiple items are changed, multiple items may be present in the update:
OUTPUT LABELS:↵
7 New output 8 label↵
10 New output 11 label↵
↵
Requesting Changes
To update a label, lock or route, the client should send a block of the same form the multi view sends
when its status changes. For example, to change the route of output port 8 to input port 3, the client
should send the following block:
VIDEO OUTPUT ROUTING:↵
7 2↵
↵
The block must be terminated by a blank line. On receipt of a blank line, the multi view will either
acknowledge the request by responding:
ACK↵
↵
or indicate that the request was not understood by responding:
NAK↵
↵
After a positive response, the client should expect to see a status update from the MultiView showing
the status change. This is likely to be the same as the command that was sent, but if the request could
not be performed, or other changes were made simultaneously by other clients, there may be more

Developer Information
20
updates in the block, or more blocks. Simultaneous updates could cancel each other out, leading to
a response that is different to that expected.
In the absence of simultaneous updates, the dialog expected for a simple label change is as follows:
OUTPUT LABELS:↵
6 new output label seven↵
↵
ACK↵
↵
OUTPUT LABELS:↵
6 new output label seven↵
↵
The asynchronous nature of the responses means that a client should never rely on the desired update
actually occurring and must simply watch for status updates from the MultiView and use only these
to update its local representation of the server state.
Requesting a Status Dump
The client may request that the MultiView resend the complete state of any status block by sending
the header of the block, followed by a blank line. In the following example, the client requests the
MultiView resend the output labels:
OUTPUT LABELS:↵
↵
ACK↵
↵
OUTPUT LABELS:↵
0 output label 1↵
1 output label 2↵
2 output label 3↵
…
↵
Checking the Connection
While the connection to the MultiView is established, a client may send a special no-operation
command to check that the MultiView is still responding:
PING:↵
↵
If the MultiView is responding, it will respond with an ACK message as for any other recognized command.
