Explain the application of NDI transmission protocol technology in detail

What does NDI mean?
What is NDI? It is the abbreviation of Network Device Interface, which is an IP network device interface protocol.
NDI is an open protocol that enables video-compatible products to share video over a local area network.
The detailed explanation of the NDI protocol is that in a single production environment, any NDI device can be connected to all other devices, each signal source can be the target location, and NDI will be able to flexibly obtain any signal input and output. It is a completely innovative IP working mode.
Newtek NDI Protocol The
NDI protocol can transmit and receive multiple broadcast-level quality signals through the IP network in real time. At the same time, it has the characteristics of low latency, accurate frame video, mutual identification of data streams, and communication.
Many foreign TV stations have converted the traditional SDI/HDMI video transmission form to NDI network transmission. NDI is a new network application field that simplifies the signal transmission of the system.
NDI makes system design, integration, application, maintenance, and function expansion simpler and more flexible in signal, call, and multiplexing.
Features of NDI:
1. After NDI encoding, NDI audio and video signals can transmit and receive multi-broadcast quality signals in real time through the IP network.
2. At the same time, it has the characteristics of low delay, accurate frame video, mutual recognition of data streams and communication.
NDI application scenarios:
NDI can directly hot-shoe cameras, can encode SDI or HDMI video sources into NDI protocol streams, transmit video through wired or wireless WIFI networks, and transmit video through wired or wireless WIFI networks, reducing wiring costs and The deployment time satisfies the needs of studios and on-site multi-camera video production.
Advantages of NDI encoder:
Built-in 5G enhanced WIFI module, which can realize more stable wireless transmission, and supports USB expansion for wired network transmission;
Built-in large-capacity lithium battery power supply, also supports 5-16v external mobile power supply, no need to consider wired power supply;
active heat dissipation design (built-in fan), adapt to high temperature working conditions, stable and reliable operation;
portable and compact, weighs only 380g, comes with Hot shoe, easy to install the camera integrated;
support the use of mobile phone/PAD terminal APP for wireless remote management, convenient operation;
support dual stream output, the main bit rate supports 1080p60Hz video encoding, and the sub-stream supports 720p 60Hz video encoding, It can stream to two platforms at the same time;
comes with SD/TF card slot, supports local recording, and supports NAS network storage at the same time;
supports 1080p60Hz video format, output resolution can be customized;
adopts imported chips and H.264 video encoding technology, At the same time, combined with technical processing such as video dynamic noise reduction and image enhancement, it can realize low bit rate encoding and guarantee high-definition picture quality;
