NDI (Network Device Interface)
technology provides the ability for multiple video systems to communicate via the
Local Area Network by eliminating the requirement for Video cables like HDMI, DVI and SDI for streaming providing
convenience and versatility. The technology was developed by NewTek to simplify remote connections and
streaming, capture/playback, replay and production.
NDI cameras support bi-directional communication featuring ultra-low latency and ultra-high video streams on
shared connections. Network requirements include 1GB Network using CAT5/6 cables for connectivity. Software
programs offering NDI capturing will typically require NDI plugging be installed.
Note – NDI streaming uses more bandwidth than most streaming devices using standard video cables and capture
devices. For this reason, it is recommended when using more than (2) NDI camera simultaneously it is a good idea
to implement VLAN’s. VLANS provide the ability to divide and segment Network bandwidth to optimize streaming
without sacrificing quality of the stream or possible streaming interruptions from other devices connecting to the
network. If you are having issues with streaming smoothly, this may be caused by Network traffic and a lack of
bandwidth on the LAN.
EXAMPLES of standard NDI Versus NDI| HX Streaming Bandwidth Usage:
•
1920×1080@30 fps NDI stream requires minimum of 125 Mbps of dedicated bandwidth.
•
1920×1080@30 fps NDI|HX stream requires minimum of 8 to 20 Mbps of dedicated bandwidth.
Common Software Programs supporting NDI Plugins: (These plugins will need to be download for your program)
vMix / OBS Studio’s / VLC / Wirecast / Epiphan / ProPresenter
