BRIDGE NDI 3G is housed in a compact 1RU chassis and yet 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.

Remote or Local Control

BRIDGE NDI 3G can be controlled locally using a mouse and keyboard with the appropriate VGA-capable monitor. All functionality of BRIDGE NDI 3G is also accessible remotely, allowing easy control via the same intuitive UI.

Video and Audio Support

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, with 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.

SDI Outputs can Freerun or use an External Reference for timing. System wide audio default can be set for 2, 8, or 16-channels of audio across SDI and NDI I/O.

Operational Flexibility

BRIDGE NDI 3G offers enormous flexibility in how all 16-channels can be utilized:


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 Decoded Output via dual 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.
