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.
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.
They 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.
