Welcome to VDO360, your trusted source for advanced video solutions! Are you wondering about the difference between NDI and NDI HX? Look no further for the answer! Our comprehensive understanding of these technologies provides us with the insights you need to make an informed decision.

NDI (Network Device Interface) and NDI HX (High Efficiency) are revolutionary technologies enabling high-quality video streaming and communication over IP networks. While they share the same underlying principles, some key differences are worth noting.

NDI is a versatile IP video protocol that delivers low-latency, high-quality video, and audio signals over standard Ethernet networks. It offers exceptional video clarity and can handle resolutions up to 4K, making it an ideal choice for professional video production and broadcasting.

On the other hand, NDI HX is a more bandwidth-efficient variant of NDI. It utilizes advanced compression algorithms to deliver excellent video quality while reducing the required network bandwidth. NDI HX is specifically designed for applications with bandwidth limitations, such as wireless or internet-based streaming, which are a concern.

The main difference between NDI and NDI HX lies in their bandwidth requirements. NDI HX allows for smoother video streaming and reduces the strain on your network. It is an excellent choice for situations where network resources are limited or when streaming over wireless connections.

Both NDI and NDI HX offers numerous benefits, including low latency, high-quality video, and flexible integration with a wide range of devices and software. They revolutionize how video is transmitted, making it easier to create professional-grade video productions.

In this article, we’ll examine the differences between NDI Hx and how they differ from each other. Before we go any further, let’s briefly explain the purpose of each encoding type. In addition, we’ll examine how NDI encodes video. NDI HX is intended for use with video production software such as Adobe Premiere Pro.

NDI vs NDI HX

NDI enables local area network devices to transmit high-quality signals over the same channel. Both NDI HX support multiple simultaneous streams. NDI has a low end-to-end delay, typically less than 100ms, while NDI HX has a larger delay of up to 300ms. If you’re evaluating the benefits of NDI for your organization, make sure to compare the differences between the two protocols.

While the two protocols are very similar, NDI uses more bandwidth, while HX does not. NDI uses 150 Mbps for 1080p60 transmissions while NDI HX uses only one to 50 Mbps. However, NDI HX has improved its compatibility with ARM-based devices, and the latest version of NDI supports H.265 codecs.

NDI HX is a higher-efficiency NDI specification. H.264 compression chips are integrated into NDI HX devices, making it easier for more hardware to support the standard. NDI HX has the benefit of low bandwidth requirements and supports multiple video streams on a simple network. It is also less prone to jitter, and its H.264 codec is faster.

NDI encoding

NDI encoding and NDIDex are standards that allow the exchange of video and audio over a network. This protocol carries both audio and video in one packet, and enables the exchange of metadata as well. NDI supports both asynchronous and synchronous streams. The protocol allows metadata messages to be sent in both directions and supports a large number of simultaneous streams. Furthermore, NDI encoding and NDIDex support a wide variety of different combinations of streams, including audio-only connections.

NDI encoding and NDIDex use different video compression standards. NDIHX is a compressed version of the standard, using GOP encoding, whereas full NDI uses I-frame encoding. In addition, NDIHX has higher latency and one-frame video delay, while NDIDex uses H.264 video compression. However, NDIHX requires less bandwidth than NDIDex. Full NDI requires 125 Mbps of dedicated bandwidth for a 1920×1080@30fps NDI stream, while NDIDex needs eight to 20 Mbps of dedicated bandwidth.

NDIHX is the latest version of NDI. It has more powerful built-in h.264 compression chips, and is more flexible than NDIHX2. In addition, NDIHX allows for multiple video streams on Gigabit networks. NDI is NewTek’s innovative Network Device Interface technology. It provides a connection between compatible systems and applications over an IP network. StreamStar and LiveStream Studio are both NDI HX compliant applications.

For 1080p60 streams, Full bandwidth NDI® utilizes about ~150Mbps with latencies of ~16ms, whereas HX can use anything between 1~50Mbps with latencies ranging between 80-200ms depending on the equipment used.
