1. Firstly let’s review what’s NDI technology.
Network Device Interface (NDI) is an IP network device interface protocol.
The NDI protocol is an open protocol for video sharing over a local area network.
Compared with coaxial cable transmission, the transmission of NDI is more price-competitive, more stable, and more resistant to interference.
NDI transmission technology is a high-quality, low-latency, multi-channel IP video transmission standard pioneered by NewTek.
Multiple broadcast quality signals can be transmitted and received in real time over an IP network.
A device in the LAN can output or receive multiple NDI signals through one network cable.
No complicated wiring is required, and it can be used directly in the original network environment and deployed quickly.
- What can NDI do?
Now many devices in broadcasting industry have already supported NDI. NDI does not need a professional switch. Gigabit network switches can be used. It is possible to have 100 high-definition NDI streams in the network at the same time. You can freely deploy NDI sources from the switch through network protocols. The architecture of the entire system integration is much simplified.
Principle of NDI transmission technology.
NDI is used in countless devices, allowing multiple video systems to recognize and communicate with other systems via IP. In addition, it encodes, transmits and receives a wide range of high quality, low latency and frame accurate video and audio in real time. This will benefit any video device connected to the network, including video mixers, graphics systems, capture cards, and a host of other production devices. In addition, it can dramatically increase the number of sources used for real-time production switching without having to connect directly to the device, change locations, or invest in expensive high-bandwidth networks, simply replacing it with an SDI-based workflow.
- What problems can NDI solve?
NewTek’s NDI transmission protocol solves the IP network problem well and can satisfy the TV station’s program requirements by using the existing network system. With Gigabit Ethernet, you can do 4K and HD programming, and you can use the existing network system to meet the TV station’s program needs. At the same time, the use of ordinary networks can also achieve satisfactory results, and truly achieve low cost and good results.
The biggest advantage of NDI: The NDI standard is open and can be used with confidence. Now many equipment manufacturers of radio and television have already supported NDI, which is compatible with traditional radio and television equipment. The architecture of the whole system integration is very simplified and compatible.
NDI can convert various signals into NDI network signals for all devices in the network to call. At the same time, the NewTek signal monitoring and monitoring system not only has 16 channels of signal switching, but also has hundreds of signal monitoring calls. This is very difficult to do in the traditional way.
The camera is set at different angles and positions, and one network cable realizes remote control of the equipment room. Let the broadcast-quality TV bloom more new ideas, and let the creative staff behind the scenes not be so hard!
