NDI® Bridge Overview

NDI® Bridge Settings

NDI® Bridge links two or more NDI® networks over the internet. For reliability you’ll need high bandwidth and low latency at each site. The Bridge service supports NDI® High Bandwidth and NDI® | HX streams.

Typical bitrates (1080p30):

  • NDI® | HX: ~10–40 Mb/s
  • NDI® High Bandwidth: ~100–140 Mb/s

Host networks require port forwarding to accept Bridge connections.


Settings

Transcoding mode

  • HX / High Bandwidth / Do not transcode
    For stability and lower bandwidth, NDI® | HX is recommended. High Bandwidth can increase quality but needs much more bandwidth and CPU.

Codec

  • For NDI® | HX, select H.264 or HEVC.

Graphics Adapter

Pick the GPU used by Bridge. Recommended: NVIDIA Quadro ADA2000 in the AXIS unit.

Compatibility

  • NDI® 4 Compatibility – rarely needed; limits output to 2 audio channels.

Quality slider

Drag the Quality slider to increase or decrease visual quality (and required bandwidth).

Throughput note: In testing, an MMG AXIS can send up to 12× 1080p30 NDI® feeds over Bridge.

Host

  1. In Settings → NDI® Bridge, set Mode to Host.
  2. Configure:
    • Bridge Name – the group name shown to remote users (must be unique on your network).
    • Encryption Key (optional) – all Join clients must use the same key.
    • Port – forward this port from your router to the AXIS.
    • Groups (Access Manager) – optionally restrict which NDI® groups are shared.
  3. Click .

Join

  1. In Settings → NDI® Bridge, set Mode to Join.
  2. Gather details from the Host:
    • Public IP address of the Host network
    • Port number the Host forwarded
    • Encryption Key (if used)
  3. Configure your Bridge Name (must be unique on your network) and any Groups to share back via Access Manager.
