What Is NDI FHD 4K Live Streaming IP PTZ Camera?
NDI is the abbreviation of Network Device Interface, which is a network device interface protocol launched by NewTek in 2015. After the audio and video signals are NDI encoded, they can transmit and receive multiple broadcast-quality signals in real time through the IP network. At the same time, they have the characteristics of low latency, accurate frame video, mutual recognition of data streams, and communication. NDI is an open protocol that enables video-compatible products to share video through the local area network. It makes the simple and efficient transmission of video in the IP space a reality. This feature and application will largely replace the current industry-specific wired connection and transmission. (Such as HDMI, SDI, etc.).
What Can NDI Bring To Us?
Replace complex connections and quickly build a studio
Using NDI network interconnection, traditional SDI/HDMI video signals can be reliably transmitted to IP-based on-site production equipment, such as various software and hardware production equipment, video mixers, image systems, etc., without the need for complicated connections. You save complicated equipment costs and maintenance costs.
You don’t need to be affected by physical factors such as space, distance, and access rights. You don’t need to lay audio and video cables between different locations. You don’t need a professional engineering team. As long as the IP network, you can connect to various production equipment in different locations and build quickly. Your lightweight studio.
Make real-time produced signal sources richer than ever before
Another significant advantage of NDI is multi-channel transmission. Each signal source can be used as multiple sink targets. The NDI data stream of any device can also be interconnected, which greatly increases the number of on-site production switching. The number of signal sources makes real-time program production more colorful.
In addition, for complex multi-process program production workflows, after deploying NDI, each work link can be processed online and distributed in parallel, which greatly improves the efficiency of program production. For example, for an event program, real-time event analysis, player statistics, media interaction, real-time playback, slow-motion playback processing, and more screen processing, etc., can be produced online and in parallel at the same time.
Comparison Between NDI|HX And FULL NDI Transmission Broadband
NDI (Network Device Interface) is an IP network device interface protocol. NDI can transmit and receive multiple broadcast-level quality signals in real time through an IP network. It can transmit high-quality audio and video signals, metadata, and control signals in a local area network with ultra-low delay. A device in the local area network can output or receive multiple NDI signals through a network cable, without complicated wiring, and can even be used directly in the original network environment for rapid deployment.
Many radio and television equipment manufacturers now support NDI. NDI does not require a professional switch, just a gigabit network switch. There may be 100 high-definition NDI streams in the network at the same time. Through the network protocol, you can freely deploy the NDI signal source from the switch. The architecture of the entire system integration will be simplified a lot.
NewTek released the NDI 4.X SDK at the 2019 IBC exhibition to support both NDI|HX and FULL NDI.
FULL NDI is a frame high bit rate protocol with ultra-low latency and almost lossless advantages. However, FULL NDI requires a lot of bandwidth.
FULL NDI bandwidth:
A single 1080P60 NDI stream requires 125Mbps,
A single 4KP60 NDI stream requires 250Mbps.
Users can transmit multi-stream high-definition NDI streams in a gigabit network environment, and FULL NDI is widely used in on-site production solutions.
FULL NDI delay: FULL NDI end-to-end delay is within 80ms;
NDI|HX is a low-bandwidth version of NDI, a compressed version of the long GOP H.264 variant, with the advantage of low bandwidth requirements.
NDI|HX bandwidth:
A single 1080P60 NDI stream only needs 10Mbps,
A single 4KP60 NDI stream only needs 20Mbps.
Therefore, video can be transmitted in a wireless network environment with a small bandwidth, and NDI|HX is widely used in application scenarios in various industries.
NDI|HX delay: NDI|HX end-to-end delay is about 100ms;
What is NDI|HX2?
NDI|HX2 is the next generation of efficient NDI protocol, it also uses H.264, although it can also use H.265 (HEVC). The main difference compared to NDI|HX is that NDI|HX2 is a true native NDI stream, from the source device all the way to the destination. This means that it is a “cleaner” implementation than NDI|HX, and can provide more reliable, lower latency and more flexible connections. It shares all the general features of NDI, such as 3 different discovery options (mDNS , NDI access polling and NDI 4 discovery server), the ability to carry arbitrary NDI metadata, and the same control over low-level network transmission (TCP, UDP, multicast, and mTCP).
With higher bit rates and HEVC options, NDI|HX2 can provide FULL NDI-like picture quality through WiFi. The NDI delay largely depends on the codec implementation in the sending and receiving devices, but in theory it can be as low as a few frames.
Thousand Vision NDI|HX codec equipment can be smoothly upgraded to NDI|HX2 version.
Principles of NDI Technology
NDI is an IP transmission technology provided by NewTek’s official website. It is used to transmit video and data through a standard network in both directions. In a single or interconnected production environment, any device can be connected to all other devices, and each signal source can also become At the target location, NDI® also provides a wealth of digital media production capabilities, improves the quality and efficiency of video codecs, uses IP for transformative media collection, capture and recording, and discovers devices across multiple networks with only one cable Can simplify the video production process.
NDI technology is simple and easy to use
NDI is a standard for IP streaming. As long as the NDI technology directly adds code to the software to output NDI or after the audio and video signals are NDI encoded, it can transmit and receive multiple broadcast quality signals through the IP network in real time, whether at home or at home. It is an office place. Using NDI® is equivalent to adding interconnected devices to the network. At the same time, it has the characteristics of low latency, accurate frame video, mutual recognition of data streams, and communication.
NDI low-cost deployment
NDI does not need to purchase patented hardware equipment and high-bandwidth networks, nor does it need to invest a lot of manpower and material resources to upgrade NDI. NDI can easily meet multiple NDI® videos as long as it is connected through a shared connection in the Gigabit Ethernet network infrastructure. , Audio and metadata streaming requirements, some designated products are even compatible with WiFi. So don’t worry about the high cost of transitioning to IP.
NDI workflow
With the help of NDI’s emerging IP mode, whether it is cameras, video converters, video capture cards, broadcast equipment, etc., can realize interconnected production workflows. NDI transmits audio and video signals through the network, and can flexibly obtain any signal input and Output. Any manufacturer or developer can integrate NDI® into the product immediately. Mainly download the NDI software, integrate the equipment and applications into the workflow, and you can effectively transmit in real time.
