BRIDGE NDI 3G Conversion Gateway Appliance v1.7 7 www.aja.com
Chapter 1 – Introduction
Overview
BRIDGE NDI 3G is a 1RU gateway offering high density conversion to and from SDI
to NDI and NDI to SDI for UltraHD/4K, HD, and SD signals. Designed to drop into
any existing NDI or SDI workflow as a plug and play appliance, BRIDGE NDI 3G is
easy to deploy and administer.
BRIDGE NDI 3G brings immense conversion power and flexibility, fully
controllable remotely for AV use, security and surveillance, broadcast, eSports,
entertainment venues, and a wide range of other facilities needing high quality,
efficient NDI encode and decode. Set and forget, or use more dynamically as
project needs dictate.
BRIDGE NDI 3G can support workflows across:
• 16 channels of HD and SD
• 4 channels of 4K/UltraHD
• 8 V+K channel pairs
• combinations of the above
NOTE: Total channel count and/or supportable rates may be reduced in some situations,
due to network conditions, video processing load, and other parameters.
NOTE: In this manual and the BRIDGE NDI 3G UI the term ‘HD’ can refer to all SDI
formats from SD to 3Gb.
Features

UltraHD up to 60p as standard
• Bidirectional encode/decode SDI to NDI, NDI to SDI, with a combination of SD
through 3Gb or 4K/UltraHD video
• Confidence monitoring

Technical Description
Engines and Banks
Engines control whether BRIDGE NDI 3G is converting SDI to NDI, or NDI to SDI,
whereas Banks control the configuration of the Inputs or Outputs (Channels or
Groups).
BRIDGE NDI 3G's internal signal processing is structured as two Engines and four
Banks. Engine A is associated with Banks 1 and 2, while Engine B is associated
with Banks 3 and 4. Each Bank has four bi-directional SDI channels with
corresponding small Din 1.0/2.3 slip-on connections on the rear of the chassis.
• Bank 1 consists of Channels 1, 2, 3, 4 (Engine A)
• Bank 2 consists of Channels 5, 6, 7, 8 (Engine A)
• Bank 3 consists of Channels 9, 10, 11, 12 (Engine B)
• Bank 4 consists of Channels 13, 14, 15, 16 (Engine B).
Each Engine also has an external reference connector.

BRIDGE NDI 3G Conversion Gateway Appliance v1.7 9 www.aja.com
Each Engine can be configured to either convert SDI to NDI, or NDI to SDI. Each
Bank determines the configuration of the Inputs or Outputs (Channels or Groups)
of that Bank's rear SDI connectors.
Grouping Channels within a Bank
Each Bank can be independently configured for one of the following:
• Four separate HD Inputs or Outputs
• Two Video and Key Input or Output pairs (two groups)
• One 4K/UltraHD Input or Output (one group)
NOTE: Groups cannot span multiple Banks.
Input and Output Configurations
If both Engines are set to convert in the same direction (SDI to NDI, or NDI to SDI),
then all four Banks will be available for a total of up to 16x individual HD channels,
4x 4K/UltraHD Groups, or 8x V+K Groups, or some combination thereof.
If one Engine is set to convert SDI to NDI, and the other Engine is set to convert
NDI to SDI, then there will be two Banks available in each direction, for a total of
up to 8x individual HD channels In and Out, 2x 4K/UltraHD Groups In and Out, or
4x V+K Groups In and Out, or some combination thereof.
Network Capabilities
BRIDGE NDI 3G ships configured for DHCP operation.
Media vs Control Networks
BRIDGE NDI 3G is equipped with two internal Network Interface Cards (NICs), each
10GigE capable, supporting simultaneous operation over two separate networks
(Media and Control).
The Media Network can be a dedicated NDI network that carries just the NDI
traffic. If you are working in a single network environment, you can use the Media
Network for both NDI traffic and system control.
Using a separate Control Network allows you to connect your BRIDGE NDI 3G to a
general facility network without the concern of swamping that network with high
bandwidth NDI signals. This method allows you to safely access BRIDGE NDI 3G
from anywhere in your facility or Virtual Private Network (VPN).
Unicast Supported
BRIDGE NDI 3G supports Unicast. Multicast is not supported.
NDI Support
BRIDGE NDI 3G is compatible for NDI input (receive) and output (transmit)
with both NDI 4.x and NDI 5.x software/hardware. For NDI input, NDI HX is also
supported.
Chassis Description
The BRIDGE NDI 3G has a 1RU height rack mountable chassis with hot swappable
redundant power supplies.

The main power switch is used to apply or remove power from the power supply
to the system. Turning off system power with this button removes the main
power but keeps standby power supplied to the system.

Cabling
NOTE: SDI connections, including input or output signal direction, are affected by the
current BRIDGE NDI 3G's system configuration settings.
The SDI connectors on the cards in the chassis are associated with the following
Engines, Banks, and Channels (see Table 1). Each Engine can be configured for
either SDI input or SDI output.
