Overview
BRIDGE NDI 3G is a 1RU gateway offering high density conversion from 3G-SDI to NDI and NDI to 3G-SDI for both multi-channel HD and 4K/UltraHD. Designed to drop into any existing NDI or SDI workflow as a plug-and-play appliance, it's 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.

Remote or Local Control
BRIDGE NDI 3G is accessible remotely using a web browser. Alternatively, BRIDGE NDI can be controlled locally using a mouse and keyboard with the appropriate VGA-capable monitor. In either case, the same intuitive UI allows easy control of all BRIDGE NDI functionality.
NDI Network Discovery
BRIDGE NDI 3G has a dedicated Source/Destination interface for viewing and managing your NDI network and its available sources. BRIDGE NDI scans the network and enumerates NDI sources. Different discovery modes can be used to reduce the burden of updating in very busy environments.
This powerful toolset allows a birds-eye view across the NDI network, including searching, naming, and even favoriting. It is also at this place in the interface where users can choose to make use of an external discovery server. When doing so, the BRIDGE NDI Source/Destination interface will continue to update, but now based on the information flowing from a dedicated discovery server, which is best practice when dealing with high volume NDI networks.
Professional Video and Audio Toolset
SDI I/O: BRIDGE NDI 3G supports YCbCr, 4:2:2 10-bit video with up to 16 embedded channels of audio, up to HD and 4K/UltraHD 60p. 4K/UltraHD SDI I/O supports either Square Division or 2SI.
NDI I/O: BRIDGE NDI 3G supports UYVY, 4:2:2, 8-bit, or P216, 4:2:2, 16-bit (support for output only), again with up to 16 embedded channels of audio, and up to HD and 4K/UltraHD 60p.
Genlock: SDI outputs can Freerun or use an External Reference for timing.
Audio: System wide audio can be set for 2, 8, or 16-channels of audio across SDI and NDI I/O.
Timecode: Use Auto mode to make life easy, or dial in specifics if you are looking for VITC1, VITC2, LTC, or Time-of-Day.
Blackout/Disable: Individual video channels/groups can be blacked out (video mute)
Mute: Individual video channels/groups can have audio muted
Test Patterns: Send out test patterns during installation or studio setup
BRIDGE NDI 3G Supports Full Raster DCI 4K
BRIDGE NDI 3G supports up to the full 4K (4096x2160) DCI (Digital Cinema Initiatives) raster dimension. The full DCI raster is important to cinema workflows and to anyone looking to get the highest quality out of every pixel.
DCI over SDI in BRIDGE NDI 3G is supported by maintaining the native raster/aspect ratio of a film and centering the image on black, ensuring the final raster size for a given digital cinema project will utilize either the full width or height of the DCI raster.
A few examples are 1.85 Flat @ 3996x2160 and 2.37 Scope @ 4096x1716, both of which are delivered as a 4096x2160 raster with black padding.
Operational Flexibility
BRIDGE NDI 3G offers enormous flexibility in how all 16-channels can be utilized:
HD I/O
All HD channels can be used to encode from SDI to NDI or decode from NDI to SDI.
HD Video and Key I/O
HD channels can also be allocated into V+K groups enabling dual V+K SDI signals to be combined and encoded into a single NDI output with alpha channel. Conversely, a single NDI input with alpha channel will be decoded and output as dual V+K SDI signals.
4K/UltraHD I/O
HD channels can also be placed into 4K/UltraHD groups enabling dual or quad SDI signals to be used for 4K/UltraHD encode from SDI to NDI, or decode from NDI to SDI with support for both Square Division and 2SI.
Simultaneous Encode and Decode
BRIDGE NDI 3G is also able to encode SDI to NDI and decode NDI to SDI simultaneously, offering a gateway conversion that can connect SDI and NDI work areas with ease.
All Encode
BRIDGE NDI 3G can be configured so that it encodes all incoming SDI inputs to NDI outputs. This mode supports the following:
Number of Simultaneous 3G-SDI Inputs
-
16x Simultaneous up to 60p YCbCr 4:2:2 10-bit
Simultaneous Encodes for Individual HD Channels (1080p)
-
16x Simultaneous up to 60p
Simultaneous Encodes for HD Video and Key Pairs (1080p)
-
8x Simultaneous up to 60p
Simultaneous Encodes for 4K/UltraHD Groups (2160p)
-
4x Simultaneous up to 60p
Supported Encoded Output via 10GigE
-
NDI UYVY, 4:2:2, 8-bit, or P216, 4:2:2, 16-bit
BRIDGE NDI 3G can accept up to 16 incoming HD baseband video signals via 3G-SDI and apply NDI encode to each, allowing up to 16 individual HD NDI channels to be output via 10GigE. Those 16-channels of 3G-SDI can also be utilized to enable eight dual channel Video and Key Groups to NDI outputs or four quad or dual channel 4K/UltraHD Groups to NDI outputs.
All Decode
BRIDGE NDI 3G can be configured so that it decodes all incoming NDI inputs via 10GigE ports directly to the SDI outputs. This mode offers the following:
Simultaneous NDI / NDI HX Inputs
-
4, 8, or 16x Simultaneous up to 60p, UYVY, 4:2:2, 8-bit
Simultaneous Decodes for HD (1080p)
-
16x Simultaneous up to 60p
Simultaneous HD Video and Key Decode Pairs (1080p)
-
8x Simultaneous up to 60p
Simultaneous 4K/UltraHD Decodes (2160p)
-
4x Simultaneous up to 60p
Supported Encoded Output via 10GigE
-
YCbCr 4:2:2 10-bit
Up to 16x NDI or NDI HX inputs can be decoded to uncompressed baseband HD video for output via 16x 3G-SDI outputs.
BRIDGE NDI can also decode up to 8x NDI streams plus alpha channel for conversion and output as 8x dual 3G-SDI HD Video and Key channels. And when decoding up to 4x 4K/UltraHD NDI streams, the 16x connections can support either Square Division or 2SI for SDI output.
Encode/Decode Combination
It’s also possible to utilize the BRIDGE NDI 3G to provide a combination of both decode NDI to SDI and encode SDI to NDI.
For an all HD workflow where both encode (SDI to NDI) and decode (NDI to SDI) are needed simultaneously, BRIDGE NDI 3G supports 8-channels in each direction.
Hardware
BRIDGE NDI 3G is housed in a compact 1RU chassis and offers high density I/O with 16 bidirectional 3G-SDI connectors as compact DIN 1.0/2.3 spigots for all baseband video inputs and outputs. Included with BRIDGE NDI 3G are 18x DIN 1.0/2.3 to BNC connectors to make installation into an existing SDI infrastructure easy. BRIDGE NDI 3G boasts dual 10GigE ports for control and all NDI I/O, providing support for up to 16-channels of incoming or outgoing NDI streams.
