NDI (Network Device Interface) is a protocol that allows high-quality, low-latency video, audio, and metadata transmission over standard Ethernet networks. It benefits remote production by enabling seamless integration of video sources across different locations without the need for specialized cabling or infrastructure.

The hardware requirements include an Ethernet network with sufficient bandwidth, NDI-compatible cameras and devices (such as PTZOptics cameras), and NDI converters if using non-NDI cameras. A robust computer capable of handling multiple video streams is also necessary.

NDI can be used with many video production software solutions, including vMix, OBS, NewTek TriCaster, and Wirecast. Ensure your chosen software supports NDI inputs and outputs.

Connect remote cameras to your network using NDI-native cameras or NDI converters for non-NDI cameras. Ensure all devices are on the same network and subnet, and configure them in your production software to receive the NDI feeds. You can then use NDI Bridge or PTZOptics Hive to send and receive those video sources on the far end.

Use a Gigabit Ethernet network or higher to handle the high bandwidth requirements of NDI streams. Ensure all NDI devices are on the same network and subnet, and consider using dedicated network segments for NDI traffic to avoid congestion.

The bandwidth requirement depends on the resolution and frame rate of the video stream. For example, a 1080p60 NDI stream typically requires around 125 Mbps. Ensure your network can handle the total bandwidth needed for all NDI streams.

NewTek provides a suite of free applications called NDI Tools, which includes NDI Scan Converter, NDI Studio Monitor, NDI Virtual Input, and more. These tools help manage and monitor NDI streams.

NDI for Remote Production Workflow

NDI Bridge is a tool designed for sharing NDI video sources beyond a local area network (LAN) using the Wide Area Network (WAN), also known as the “Public Internet.” NDI Bridge was released in 2021 with the NDI 5.0 toolset, along with NDI for Remote Production and Audio Direct tools. 

NDI Bridge Workflow

Until NDI Bridge was released, many video productions used NDI only for LAN video traffic and relied on technologies such as Secure Reliable Transport (SRT) or video communication solutions like Zoom to transport video over the public internet. NDI 5.0 supports a technology called Reliable User Datagram Protocol (RUDP) which is a point-to-point video transport protocol that allows for high quality video transport over public networks. 

NDI Bridge is a tool within the NDI ecosystem that allows for secure, high-quality transmission of NDI video and audio streams over the internet between different locations. It effectively "bridges" separate networks, enabling remote production and collaboration.

NDI Bridge allows for seamless integration of remote video sources by connecting different network locations over the internet. This capability enables remote production teams to collaborate and manage live streams from multiple locations, enhancing flexibility and production quality.

The hardware requirements include a computer with sufficient processing power and network capabilities to handle the NDI streams. A stable and high-bandwidth internet connection is also crucial to ensure smooth transmission of video and audio streams.

Both locations connected via NDI Bridge should have stable, high-bandwidth internet connections. Proper network configurations, such as port forwarding and firewall adjustments, may be required to ensure that NDI traffic can flow freely between the networks.

Setting up NDI Bridge involves: Installing NDI Tools, which includes NDI Bridge. Configuring the NDI Bridge settings, such as specifying the IP addresses of the remote locations. Ensuring network configurations like port forwarding are correctly set up. Starting the NDI Bridge on both ends to establish the connection.

Latency depends on the internet connection quality and distance between the connected locations. Generally, NDI Bridge aims to minimize latency, but users should expect some delay, especially over long distances or less reliable internet connections.

Yes, NDI Bridge can handle multiple video streams simultaneously, provided the network and hardware resources are sufficient to manage the bandwidth and processing requirements.

NDI Bridge includes security features such as encryption to protect video and audio streams during transmission. It is designed to ensure that only authorized devices can access the streams, providing a secure solution for remote production.

The recommended internet speed depends on the resolution and number of NDI streams. For example, a 1080p60 NDI stream typically requires around 125 Mbps. Ensure your internet connection can handle the total bandwidth required for all NDI streams being transmitted.

The recommended internet speed depends on the resolution and number of NDI streams. For example, a 1080p60 NDI stream typically requires around 125 Mbps. Ensure your internet connection can handle the total bandwidth required for all NDI streams being transmitted.

NDI Bridge Host and Client Bridge

The NDI Bridge has three main components that allow users to advertise and transport NDI video over the WAN. First, users can set up their Host connection. The Host connection allows others to join the NDI Bridge that is set-up on one side of the connection. Here, you can select a group of NDI sources to be transported over the WAN to a receiving location anywhere in the world. You will learn more about setting up groups of NDI sources with Access Manager in the next chapter. Using NDI Groups, the NDI Bridge can send an entire group of NDI HB or NDI HX video sources together over the public internet.

Technical Requirements

While NDI Bridge does have some technical requirements before it can work, it provides powerful connectivity options. In comparison to established wide area network (WAN) video transport solutions like Secure Reliable Transport (SRT), NDI simplifies set-up by requiring  a single port to support multiple video channels. NDI Bridge provides the opportunity for many productions to think outside of their own local area networks (LAN) to implement video projects that incorporate video from around the world.

Additional NDI Bridge Functions

From the far end of an NDI Bridge connection, the same outside IP address and port number information is necessary to send video. Once both ends of the NDI Bridge are connected, the NDI sources available on the host side will be made available for the far end side to use just like local NDI sources. 

Tally, KVM, Metadata and more

NDI Bridge supports NDI video source capabilities including alpha channel, PTZ controls, KVM, Tally, and Metadata. Alpha channel support is necessary for many broadcast graphics applications. Graphics overlays are a use case for NDI Bridge used with alpha channel video. Alpha channel video supports a transparent background that  overlays on top of another video source. In this way, NDI Bridge allows remote productions to bring alpha channel graphics into a production environment from anywhere in the world. 

What about Remote PTZ Controls?

PTZ camera controls open up another interesting use case in which NDI Bridge is used to send video from a PTZ camera where the PTZ cameras can be controlled from a remote location. KVM, a popular abbreviation for “Keyboard, Video, and Mouse” can be used to pass along remote controls for computer screens captured with KVM support. 

NDI Bridge will also maintain support for Tally,  the technology that alerts camera operators and on-screen talent when a camera is in use. This is an interesting feature which would allow a remote production to know when a specific NDI video source is being used even from a remote production. The Tally feature of NDI will be discussed in more detail in Chapter 19. Finally, some metadata is also transported over the NDI Bridge which includes information such as NDI source-friendly names. Metadata makes NDI video more usable by providing information that compatible NDI systems can use to display relevant information to producers working with the video.
