BRIDGE NDI 3G Conversion Gateway Appliance v1.0 7 www.aja.com
Chapter 2 – Introduction to BRIDGE NDI 3G
Overview
BRIDGE NDI 3G is a 1RU gateway offering high density conversion to and
from 3G-SDI to NDI and NDI to 3G-SDI for both HD and 4K/UltraHD. 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 can support workflows across:
• 16 channels of HD
• 4 channels of 4K/UltraHD
• 8 V+K channel pairs
• combinations of the above
Maximum Performance
BRIDGE NDI 3G supports maximum performance up to 16 channels of HD
p60 or 4 channels of 4K p60. Network conditions, video processing load and
other parameters may reduce channel count and/or supportable rates in some
situations.
Common Use Cases
AJA BRIDGE NDI 3G provides efficient, high-density integration of 3G-SDI and NDI
ecosystems.
BRIDGE NDI 3G makes it easy to connect between NDI environments and SDI
environments.
In some instances BRIDGE NDI 3G may be used to connect NDI production islands
to facility SDI routers (for example, a podcast room within a larger broadcast
facility). In other situations BRIDGE NDI 3G may provide a predominantly NDI
facility with its edge interconnect for SDI feeds in and/or out.
Alternatively, AJA BRIDGE NDI 3G can be used in conjunction with AJA Bridge Live
to enable moving content over private lines or the public Internet.

• On-set monitoring distribution
Post
• Share SDI channels between numerous NDI enabled NLEs
• Cost effective video monitoring
Operational Flexibility
BRIDGE NDI 3G's video channels can be used to:
1. Encode all SDI Inputs to NDI
2. Decode all NDI Inputs to SDI
3. Encode/Decode a combination of SDI and NDI.
Encode All SDI Inputs to NDI
In All Encode mode, all channels of SDI (16x channels of HD or 4x channels of 4K/
UltraHD or 8x channels of HD V+K) are encoding from 3G-SDI to NDI.
Decode All NDI Inputs to SDI
In All Decode mode, all channels of NDI (16x channels of HD or 4x channels of 4K/
UltraHD or 8x channels of HD V+K) are decoding from NDI to 3G-SDI.
Encode/Decode Combination
In Encode/Decode Combination mode, 8x channels of HD or 2x channels of
4K/UltraHD or 4x channels of HD V+K are encoding from SDI to NDI, while 8x
channels of HD or 2x channels of 4K/UltraHD or 4x channels of HD V+K are
decoding from NDI to SDI.

Chassis Power Button
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. Therefore, you must
unplug all system power cords before servicing.

Rear Panel Power Supply LEDs
On the rear of each power supply module, an LED indicates its status as follows.
• Solid Green: When illuminated, indicates that the power supply is on.
• Solid Amber: When illuminated, indicates the power supply is plugged in and
turned off, or the system is off but in an abnormal state.
• Blinking Amber: When blinking, this system power supply temperature has
reached 63°C. The system will automatically power-down when the power
supply temperature reaches 70°C and restarts when the power supply
temperature goes below 60°C.
