NDI Converters

NDI Converters: Manufactures, Types, Features & Applications

Overview

NDI (Network Device Interface) converters are devices that allow video and audio signals to be transmitted over IP networks. They are designed to convert traditional video signals, such as HDMI or SDI, into NDI streams, which can then be transmitted over an Ethernet network.

NDI converters are useful in a wide range of applications, from live events and broadcast production to video conferencing and remote collaboration. They enable users to connect cameras, video switchers, and other devices to a network, and transmit high-quality video and audio signals in real-time.

The ability of NDI converters to transmit video signals over long distances without the use of additional cabling or signal boosters is one of their main advantages. Since traditional cabling can be challenging or impractical, they are perfect for use in large venues or at outdoor events.

NDI converters also provide a high level of scalability and flexibility. They can easily be integrated with other NDI-capable devices, such as video switchers or production software, and are used to connect multiple cameras or devices to a single network.

Some popular NDI converters on the market include the BirdDog Studio NDI, the NewTek Spark Plus, and the Magewell Pro Convert. These devices offer a range of features, such as support for multiple video resolutions, audio embedding and de-embedding, and power-over-Ethernet (PoE) support.

 

Classifications of NDI Converters

Based on their features, functionalities, and form factors, NDI (Network Device Interface) converters can be categorized in a number of ways. Following are a few NDI converters’ typical divisions:

 

1. Input/output type: NDI converters can be classified based on the type of input and output connections they support. Some common input/output types include HDMI, SDI, and analog audio and video.
2. Form factor: NDI converters can be classified based on their physical form factor, which can include portable, rackmount, or desktop units. Portable NDI converters are compact and easy to carry, while rackmount units are designed for use in broadcast or production facilities.
3. Resolution support: NDI converters can be classified based on the resolution of the video signals they support. Some NDI converters are capable of supporting 4K and high frame rate video signals, while others are limited to lower resolutions.
4. Audio support: NDI converters can also be classified based on their audio capabilities. Some converters support embedded audio, while others support analog audio inputs and outputs.
5. Power options: NDI converters can be classified based on their power options. Some devices can be powered over Ethernet (PoE), while others require an external power supply.

 

Examples of NDI converters that fall into these classifications include the NewTek Spark Plus, which is a portable HDMI-to-NDI converter, the BirdDog Studio NDI, which is a rackmount unit that supports SDI and HDMI inputs, and the Magewell Pro Convert HDMI TX, which is a budget-friendly HDMI-to-NDI converter that supports 1080p video signals.

Using the Kiloview NDI Converter to Perform NDI Streaming

The general steps for using the Kiloview NDI converter to perform NDI streaming are as follows:

 

1. Connect your video source (camera, video mixer, etc.) to the Kiloview NDI converter using an HDMI or SDI cable.
2. Connect the Kiloview NDI converter to your local network using an Ethernet cable.
3. Power on the Kiloview NDI converter.
4. Install and launch your NDI-compatible software on your computers or another device, such as OBS (Open Broadcasting Software) or vMix.
5. In the NDI software, look for the Kiloview NDI converter in the list of available NDI sources. It should appear with a name that matches the model of the converter.
6. Select the Kiloview NDI converter as the video source in your NDI software.
7. Configure the settings for your stream, including the resolution, frame rate, and bit rate. You may also need to configure your audio settings.
8. Start the stream from your NDI software.
9. If you want to view the NDI stream on another device or in another location, you can use an NDI-compatible media player or decoder to receive and display the stream.

 

Remember that depending on the model and software you are using, the precise configuration procedures for the Kiloview NDI converter and your NDI software may change. To ensure successful NDI streaming, it is crucial to refer to the user manual for your equipment and carefully follow the instructions.

SDI Vs. NDI

SDI (Serial Digital Interface) and NDI (Network Device Interface) are two types of video technologies that serve different purposes.

 

Uncompressed video and audio signals are transmitted over coaxial cables using the SDI digital interface.  In the broadcasting and expert video production industries, it is a widely used standard. Widely used in post-production and video production workflows, SDI signals deliver a dependable, high-quality video signal over a manageably short distance. Cameras, switchers, and other video production equipment are frequently connected using SDI cables.

 

Contrarily, NDI is a network-based video technology that enables the transmission of video and audio signals over Ethernet networks. The NewTek-developed NDI protocol is a proprietary one that streamlines video production processes and eliminates the need for physical cabling. Multiple video signals may be transmitted over a single network connection using the high-quality, low-latency NDI video protocol. It is excellent for live video production and streaming applications because it supports real-time video, audio, and metadata transmission over IP networks.

 

NDI’s adaptability and scalability are two of its main benefits. A single production workflow can easily incorporate multiple video sources thanks to the network connectivity of NDI-capable devices. In situations where cabling is difficult or impossible, NDI also supports wireless transmission, which may be helpful.

 

Finally, it can be said that SDI and NDI are two distinct video technologies with distinct uses. While NDI is a network-based video technology that enables the transmission of video signals over Ethernet networks, SDI is a trusted and widely used digital interface for transmitting video signals over coaxial cables.  NDI is increasingly being used in live video production and streaming applications in contrast to SDI, which is frequently used in professional video production workflows because of its flexibility, scalability, and low-latency performance.
